From what I've heard about the forward-assist from friends is some people use it, most don't, some use it professionally, some people like to pretend they're professionals and use it & some people like the idea of having in case they need to use it.
When I was in the Army in 69/70 we used a combination of the M16A1 & its predecessor. Both seemed to jam to easily, despite our efforts at trying to keep them clean. We used a silicone-based lubricant/cleaner called LSA that we carried in little plastic squeeze bottles for cleaning during disassembly. I field-stripped both models but don't recall the bolt carrier on either model being hard-chrome plated, looked like plain steel to me at the time.
The one in this vid has the forward assist. The main reliability problems of the M16 was the shitty ammo they were initially provided with in the beginning, fouling and dirtying up everything, making it prone to jam and overheat, true to any m16.. The 3 round burst A2 does not jam more than any other M16 rifle, but if you release the trigger before the 3 round burst operation is fully completed, and then pull the trigger again, it will fire semi, then pull the trigger again, it will fire burst.
@pred123424 nice response, but there is some mistakes on it, the m1 garand used 8 round clips and there is a modern version of the m16 that fires full auto, you know that the US military adopted 4 basic variants of the m16, the m16a1, the one used in vietnam, with full auto capability and 20 round mag well know as a unreliable weapon, the m16 a2, an enhanced version, with heavier barrel and better reability and 3 round burst, the m16a3, basically a m16a2 with full auto capability and picattiny
@doctorwho0077 I don't remember the XM16E having a forward bolt assist. The M!^A1 that we also used did have one, but not it's predecessor. In any case, the forward bolt assist never worked for me when my gun jammed, which was often. I almost invariably had to break the rifle down to clear the jam.
@THX14438 Wrong. There was always a buffer. They didn't issue cleaning kits. The barrel, bolt, barrel extension, and bolt carrier were not chrome-lined and finally, the stretched out and re-heated the buffer springs.
very informative learned things i never realized i just wish i purchased a surplus when younger befor price got high never saw prices on m1 but the users were on sale when Woolworths sold firearms went for something like $35.00
@cbb8991 Didn't have the dyes for stamping out the aluminum and plus it would cost just a little bit more than Macnamara buggeted for because it has to have an anti-tilt follower, a longer spring, and more metal on the lower portion of the magazine. Plus, the original intent was to be able to get to the ground as low as possible.
I like how some people who have never served let alone issued this weapon system know everything about it, and tell people with experience that they are wrong. from one veteran to another, thanks for your service Alien. ---------------------------------------- P.S. if you got to 1776PatriotTeen's page there are video's of this tool that will make you laugh
Can't you just picture yourself sitting in a dark smelly room watching this training video, bored out of your mind, smoking a cigarette of course, and only thinking about what bar you were going to hit with the boys that night. :)
The m16 jammed so much because they didn't know how to lubricate it properly and told solders it didn't even need to be cleaned which made it jam constantly. later they found out this stuff and it wasn't so bad and today the A2 and A4 versions are some of the best guns today
@vettelover2009 The military never went back to stick powder and the M-16 still uses ball powder..They switched to ball powder because the stick powder could not meet velocity requirements while keeping the chamber pressure to spec..The ball powder changed the bolt velocity ( too high of a cycle rate) as ball powder creates a higher port pressure. They changed the buffer to slow the bolt velocity, prevent bolt bounce malfunctions, chrome lined the bore and chamber and strengthened the extractor tension..They also lowered the calcium carbonate in the powder to lower the carbon fouling..Yes and they trained the soldiers to properly maintain their weapons..
@vettelover2009 A lot of misinformation has been spread throughout the years about the M-16. One of the best sources for the history of the M-16 is (The Black Rifle)..It chronicles the development and history..
@vettelover2009 First off, the book is the Black Rifle written by Blake Stevens and Edward Ezell who also wrote the book Kalashnikov, the arms and the man. He was a renowned gun writer who went to the Soviet Union during the cold war and was allowed to interview Kalashnikov.. Chris Bartocci wrote The Black Rifle 2... Edwars Ezell is the person doing the interviews on the Stoner videos recently released....I have also read The M16 Controversies by Thomas Mcnaugher, The Great Rifle Controversy by (once again Edward Ezell) and Misfire by William Hallahan.. So no, your information was not corroborated by other arms historians..The other powders used to replace the IMR 4475 was Dupont CR8136 and finally WC846.. I thought you or others who read your botched history lesson might be interested in the facts, since there has been a lot of misinformation put out by people who are mistaken. Instead you took it personally for some reason and called me a bum..Enough said..Have a good night..
@vettelover2009 I corroborated nothing, you were wrong. The military dropped the IMR 4475 powder right away and never used it again, just as I stated..No, the information has not changed in that time frame anymore than your ignorance..Watching you come unglued over an exchange of information that proved you wrong is hilarious..How dare anyone correct you..I never thought I would trigger you about this, amazing....You are quite entertaining, but sad and pathetic at the same time..Seek help..
Everyone assumes the M-16 is the same as the original issue. It has been improved and modified as a result of lessons learned in battle. In fact several years ago the AR-15 took two 1000yd trophys at Cp. Perry. The argument that one is better than the other is now irrelevant. Korentokulla is right its the skill of the shooter.
Straight trigger finger is a relatively new principle. GIs were not trained on that in the era of this film. I believe it was Law Enforcement that began that practice but I could be mistaken.
@ChrisPenta I read an article in the latest Esquire Magazine that suggested there were problems with the M-16 that were more severe than improper cleaning and lack of kits for cleaning. Have you read the article? According to your knowledge was the article inaccurate? I am just now learning about the History of the M-16 and I would appreciate your input?
@Marine17inlove Some bean counter decided a cheaper powder would save some money and its what lead to all the malfunctions with the early versions..Stoner got most all of this except the gas tube right the first time..Honestly for what it was intended the gas tube is still pretty smart. Yes smokeless powder has been around for over a 100 years..This issue was a stick vs. ball powder or rather mainly the texture which effects the burn rate of the powder.
Always inspect a newly given assault rifle or any other types of firearms make sure you clear the rifle and preform immediate action (sports) if the weapon has a stoppage (malfunction) preform remandile action generally disassemble and clean and lubracate the weapon to prevent sluggish operation after that assembly and operation and function test
Yes. Failure to extract as it's know today. Sometimes the case will split and the rear or case head will be ripped off and the mouth of the case will remain in the chamber rendering the weapon inoperable until the remaining piece of the cartridge is removed by way of a specialized tool appropriately called a broken case extractor.
@dellefranz i actually just bought a original pre-ban olympic arms XM177(M4 commando) copy of COLT M4 with the 10.5" bbl and 5.5" flash suppresor and all for 900$
@ehukai26 They only jammed because they were not issued cleaning kits nor trained how to properly clean the weapons. It was a failure of command, not the weapon itself.
@esh325 Agreed, the other rifles had different tolerances, but as I mentioned the m16`s are more prone to fouling with ball powder, a lesson hard learned during nam :(

The story of the first M16 rifles that were in the hands of Marines in Vietnam is fascinating and tragic. The weapon was not ready for war and jammed all of the time. By some accounts 80% of the rifles in Vietnam in 1967 were condemmed because of the jamming problems. Meanwhile the enemy's AK47 was very reliable and deadly. Those first guns never should have been put in our Marines' hands before the jamming problems were worked out
Look up the HK416 heckler and kosh fixed this problem all they did was use a short stroke gas piston instead of direct impingement...preventing fouling from fired rounds and prolonging parts they had a shoot off in an extreme dusty environment with the M4,SCAR,XM8(cancelled),and the HK416 XM8: 127 stoppages SCAR: 226 stoppages HK416: 233 stoppages M4:......882 stoppages
@AlienZygote010 No they didn't. They always had 30-rounders because it was based off of the StG-44/Mp43. That rifle had a thirty round magazine. The only AK variant that was ever issued with a 20-round magazine on the AK platform was the AMD-65 so the paratroopers still had good fire power but could get lower to the ground and have clearance for their forward-reversed pistol grip.
Biggest problem with them is that the use of a gas tube deposits all the crud right back into the action - no wonder they jam so bad. I see some enterprising folks are straightening out that little problem now - going to a piston system: the guns are cleaner & far more reliable.
i still wondering why woudld you use full auto in a real combat situation, im not aginst it, im just want to know, if some one there is on the military or something... i would like an answer
Wow, I didn't really realize that I've never heard of the M16 when it was experimental. I guess since it's such a...normal...weapon today, I took it's early stages before the M16A1 with a grain of salt.
@ehukai26 The biggest problem was that the M16 was a precision weapon with a high degree of precision in the mechanism. Therefore, any dirt, mud, sand, etc in the mechanism would cause it to jam.
My dad called this guy a jamming piece of turd. He told me that when he went into combat, he killed one enemy soldier, took his ak and fired back and used that through out the war. He told me that he barely used his M 16, or in order words he only fired about 50 before he gave it up.
I own and use both. They have both malfunctioned. I have had more serious malfunctions with Romanian AK47 style assault rifles than any other rifle I have ever shot.
They thought of them -- plenty of other weapons had them -- just not for this rifle. Gene Stoner's Stoner 63 system, which was being used by Navy Seals and others at the same time this film was made, had 30 round magazines. The AR-15/M-16 was a scaled down AR-10, and that weapon had been limited to 20 round magazines -- but this wasn't a problem because a thirty rounder in 7.62mm NATO was just too long and created difficulty shooting from the prone, so the magazine well limiting you to shorter, straight-walled magazines was not an issue. It only became an issue when they went to 5.56mm and people started wanting the extra capacity that the smaller cartridges permitted. The early M16s were stuck with 20 round magazines because they still had the AR-10's straight-walled magazine well. A straight-sided 20 round magazine works fine, but at 30, you have to introduce some curvature to cope with the taper of the cartridges (the French FAMAS has a 25 round magazine because that's as high a capacity as you can go without adding that curvature). They had serious reliability problems with early attempts at 30 round AR-15/M-16 magazines because the top part has to be straight-sided to fit in the mag well, and getting the follower to work right with a a part-curved, part-straight magazine turned out not to be so easy. The problem never was completely solved until the changeover to polymer mags made it possible to design a sturdy magazine with a constant curvature on the inside, and keep the straight-walled top part outside. Stoner always hated the 30 round AR mags because they were a kludge and suboptimal for reliability. He was able to use a 30 rounder with no problem for the Stoner 63 system because he wasn't limited by a legacy straight magazine well, and could make magazines with a constant curvature, so they always worked just fine.
@@Hibernicus1968 I am 10 years older and actually a m16 certified armorer now. I learned about several of Eugene's designs in that class. I don't think we talked about the magazines though.
no, it works. and full of mud, water, and sand it still works. the m-16 had major troubles during its first war usage. look it up. you basically have little knowledge of weapons if you think that the ak is cheap.
@curseofa5r5a at the time they were testing this weapon they were fighting the Chinese. The chinese were attacking in waves of hundreds of people. They didnt have this weapon at the time so they were using the m1 Grand. That weapon had i believe a 10 round clip and was only semi auto. The m16 could use full auto to stop the waves attacks. Now a days the m16 is not full auto. its semi or 3 round burst.
"Rifle 5.56, XM16E1 Operation and Cycle of Functioning" Well the cycle of functioning of that first model could be crammed in a 2 second tear filled video.
Thank you for this vid! I'm in the process of building an M16A1 from a parts kit, this video helped to answer a handful of questions I had.
I remember watching this movie in basic training at Ft. Gordon in 1969.
I'm glad the public has access to this training video. I always wondered what the forward assist is for
Your kidding?
No I'm serious. I've never owned or fired an AR 15 type rifle before.
From what I've heard about the forward-assist from friends is some people use it, most don't, some use it professionally, some people like to pretend they're professionals and use it & some people like the idea of having in case they need to use it.
That guy's eardrums were probably begging for mercy by the end of this shoot.
All you heard when firing an A1 was the bolt and buffer cycling. Sprang!
I'm so glad that I have ear protection!
When I was in the Army in 69/70 we used a combination of the M16A1 & its predecessor. Both seemed to jam to easily, despite our efforts at trying to keep them clean.

@ehukai26 I haven't read the article, but perhaps switching weapons in the middle of a war was inadvisable in any situation.

Or yank the charging handle till your arm fell off
Always keep the dust cover closed, sweet carrying handle.

Despite it's age this video is actually excellent.
@FRVSniperNI
You're right.
M16 had no forward assist. XM16E1 (M16A1) has the forward assist and shell deflector.
This is the rifle I carried when I first went in,,,although mine didn't have the forward assist...
these archive films are so cool
This takes me back.

Very interesting to see the original video.

Also makes for a nice little instructional video for one's first AR build, sans the full auto selector.

i cant believe that the us still uses the m16a4 and m4, it jams all the time. you can clean your rifle all the time and i still jams!
@AlienZygote010 That was a prototype. Still never issued with 20-rounders. You must be thinking of the SKS.

@AlienZygote010 ok
i always thought they never had it... but they hardly used it correct?
Does the 20-round magazine have a problem feeding if fully loaded like the 30 rounder?
@magzire it is MAGAZINE fed and gas OPERATED, not gas fed
Nice lesson there. Under what circumstances will an empty case ejection fails? there was a firing and the empty case remained in the chamber.
Yes. Failure to extract as it's know today. Sometimes the case will split and the rear or case head will be ripped off and the mouth of the case will remain in the chamber rendering the weapon inoperable until the remaining piece of the cartridge is removed by way of a specialized tool appropriately called a broken case extractor.

Why did it jam so much?

@curseofa5r5a at the time they were testing this weapon they were fighting the Chinese. The chinese were attacking in waves of hundreds of people. They didnt have this weapon at the time so they were using the m1 Grand. That weapon had i believe a 10 round clip and was only semi auto. The m16 could use full auto to stop the waves attacks. Now a days the m16 is not full auto. its semi or 3 round burst.
why is it in metric system not in imperial?
Because NATO, that's why. All things standardized by NATO are in the metric system.
