- Along with our standard RISII rail system we are also excited to bring back the RISII FSP Rail! while many of the steps for the standard installation are the same, there are a few differences with the FSP rail. In this video Joe explains how to easily install the RISII FSP Rail.

Is it possible to attach a barrel mounted m203 grenade launcher with this rail
I have a pinned and welded FSP...can the RIS II or RIS III be installed without unpinning the FSP?
Most front sight posts aren't welded, though they are pinned. Mine was a pain to unipin and reipin but I got it done. If your muzzle device is pinned and welded this won't work, because you need to be able to fully remove the front sight post.
First step use the torque wrench incorrectly ✔️
If you aren't approaching maximum rated torque, it doesn't matter unless you absolutely want to only apply a known torque, so no, not used incorrectly.
Jim Knowlton then why use the torque wrench? like using a ruler with the wrong measurements on it.
@@jimknowlton342 Civil engineer here: wrong is wrong. No justification for something like that from Daniel Defense
Also there was no seasoning of barrel nut threads, no oil on them or fsb taper pins, and no loctite on handguard screws.
@@monocogenit1 set the torque wrench to max spec and use up as much as you need.
When will the MK18 FSB cut out rail be available again?
Literally never
real question is do I use any type of loctite on the barrel nut itself and do I need to do variable torque like from 30 to 40, before reaching final torque specs of 50?
No, you do not use loctite on the barrel nut. Some kind of grease is generally recommended, though. I tend to use Aeroshell 33ms. As for torquing the barrel nut down, it's generally good practice to just go for the torque spec (in this case, 50 ft/lbs) and back it off two or three times (not using the torque wrench to break it free, as that's bad for your torque wrench). This allows the grease to really get worked into the threads so that you don't experience any kind of seizing etc. Then just tighten the barrel nut to spec and you're good to go.
Hope this helps.
Ive had one since August 30 for a Colt OEM 1 build to Block 2 clone and I still haven't installed it. I need a couple more tools ideally but Im not as confident about the install as I should be. Im unsure about removing the fsp and reinstalling it correctly without damaging anything. I'm a novice on my best day. I gotta get it done though.
Couple day install if you’re taper pins won’t come out then you’re stock barrel nut is seized 😂
Can this be used with a gas piston upper like the stag model 8? Thanks
So if I got an upper with a preinstalled fsp gas block and gas tube, I would have to remove them to install this rail, then reinstall the fsp gas block and gas tube?
Anthony Cardoza yes
Damn that sucks
Monstrum has one that you can install with the site still on the gun. Idk about their quality
Or just cut above the gas tube slide the rail on and get a new front sight
So the two steel tabs on the inside are just there for looks or what?
Its for a m203 grenade launcher
Can these railsgo on bcm carbine length fsb uppers?
Yes
Improper use of torque wrench
Some of these comments are hilarious, afraid of a little work boys?
Sad isn't it? They wouldn't know how to maintenance a lawn mower.
Would this rail be able to attach to an m4v7p?
Your barrel would be super exposed if you did.
@@MandoOutdoorson a 10.3?
will this work with a 12.5" barrel?
Yes but your rail might completely cover your barrel.
I’m curious. What is the point of this setup? Why not install the RISII with a low profile gas block and a DD fixed front sight attached to the rail? Is there a benefit other than personal preference here? It seems like having the ability to move your front sight around would be beneficial.
It’s just cool, man! 😂 plus, FSBs are literally bomb-proof.
This was designed to go onto the military m4 so they made the cutout
Number 1 is that they are made for military guns…and Number 2 is because the standard taper pinned front sight base is absolutely the most most solid option for a front sight.
Is it possible to install without the DD Bolt Up wrench?
How do you have a job for DD. Ball end wrench? Wtf is a ball end motor or a hollow ground? Do helicoils actually hold this rail together?
What size is that
The handguard is 12.25" long, so the barrel might be a 14.5
This is why I just buy complete uppers.
Because it takes 30 minutes to install a handgaurd?
@@juliannatale6743 time is money, that 30 minutes could be spent on anime hahahaha
What's up with such a respectable company producing high quality American made guns but using cheap foreign tools and toolboxes?
So THATS why they are so damn expensive
Why
Why?
I hate these rails I have 4 of them I hate them because I keep reverting to these damn things I had a knights urx3.1 clone I sold the rail to swap a ris 2 just this week
Literally the WORST rail design ever. Why would you make it so I need to remove my muzzle devise and gas bock in order to remove the rail.
Don’t remove the rail, then.
It’s pretty simple.
You're not really supposed to take the rail off
USSOCOM must like the worst rail ever then 🤷🏻♂️
It's gonna be pretty shit for civil applications, yes. Heavy, expensive, hard to install and disassemble. But this shit is made with two purpose in mind: Retain PEQ and optic zero, and mount an M203 all day, fire it all night, and not flex around.
This, is the product of that requirement. If it doesn't suit you (which it probably won't - it's a niche product in the commercial market), don't buy it. Don't use it.
No, not practical, unless you are a hardcore enthusiast. It's expensive, more difficult to install and remove, and no one will use all of the rail space. Even for SOPMOD the KAC RAS would be just fine.
