@@homevalueglass3809 I run the SMB H2 with my 10.5" AR pistol in 5.56/ .223. Works like a charm. It's obviously much more expensive, relatively speaking, than your run-of-the-mill spring and buffer combo, but I really did notice an immediate difference once I installed mine and got to the range with it. Worth every penny in my opinion.
I’m running the srs because I’m planning on running suppressed but works great unsuppressed in my 11.5. I also have a jp h2 in my 12.5 aero. Cant beat these for the price
Great looking product. I'm building an AR in a 7.62X39 platform using a BCA complete upper assembly. Could you confirm what weight buffer would be correct for that setup? I am leaning towards the SRS configuration.
Ever since HK came up with the dual spring concept (HK USP?), I am surprised that it isn't more popular on PCCs and rifles. Looks like the patents expired long ago, so there is nothing stopping this to become more popular outside pistols.
My AR has a 16" barrel with a .750 mid-length gas tube, and I got the carbine weight SRS for it, but it was not able to return to battery very frequently when I release my bolt for reloading (this won't happen if I hand charge it). I kinda solved it by putting two quarters behind the SRS in the buffer tube to give it a higher force when releasing the spring. If I wanna change to a proper weight, which would you recommand?
That is strange. I would make sure your BCG is locking back on the face of the bolt and not the BCG. That will tell us if it's fully cycling to the rear on last round hold open.
@@armaspecusa It does lock back fully to the face of the bolt carrier and so do I when manually locking it back, yet this problem still exists. I have to frequently use to the forward assist to push the bolt back to battery after releasing the bolt. (I use Sharps XPB carrier group and Strike Industries buffer tube if this can help you guys to determine the problem)
Good day all, I was considering picking up a Gen3 carbine SMB. Can the SMB be used in any type of buffer tube or are all buffer tubes similar? Thanks for reading.

SRS on carbine gas I would go with Carbine or H no heavier. with SMB you could do H or H2. SMB are easier to tune a rifle but offer less recoil reduction from our SRS. The SRS has duel springs so is best for suppressed guns and recoil reduction but is harder to tune your gun for it. Both great just depends on what you are looking for out of your build.
I have a Savage MSR 15 Recon. The buffer weight is 3oz. I run it suppressed and it’s super gassy. Ejecting at the 2 o’clock position. Well technically the 10 o’clock position. We’ll see who understands that. Now to the question. Not sure is I should go with the SMB 3.8 or 4.7? Or the SRS 3.8?
to answer the riddle part. the clock it on the same axis/orientation as the ejection port. So if you go SMB go with the H or H2. The SRS because the dual springs I would do the carbine if you run it suppressed. The srs is less forgiving when it comes to tuning. the SMB is simple and thus easier to work with in most cases. but offers less recoil reduction
@@armaspecusa ok cool. And the answer was it’s left handed. So you are correct. Depends on the ejection port. But I knew if I said 10 o’clock everyone would question it.
The only thing completely provable would be the noise reduction. Everything else is subjective without creating some sort of fixture with force sensors to objectively measure felt recoil with and without it. I own the SMB GEN 3 in H2 and love it. The gun shoots flatter and follow up shots are much easier to me, especially with an upgraded trigger of your choosing. The best you can do is watch reviews and take other people's word for it. It's a nice upgrade, but I wouldn't call it an absolute must. It's more of a quality of experience kind of thing. If you like your current set up with a standard spring and buffer combo, then save the money. Nothing wrong with that.
I’m looking at running SRS on 12.5” 5.56 and 9” 300blk both full time suppressed. Anyone have best guess on weights? Was leaning towards carbine since they say to drop down weight. TIA
I couldn't figure out how to make it work in 9mm. It has the pin in the center so the 9mm solid back bolt can't come rearward. I tried to remove the weight and had an opening for the pin but no pressure to hold the bolt closed. I think I just pissed away money and ended up with a lot of frustration. Best of luck if you try to use one.
@@anthonyschwemm I have a regular spring and a heavier longer buffer. I forget the exact weight. It works great. The smb is in my toolbox of spare parts.
@@LV_223 I think I have the 9mm one I'll get around back to it sometime. Went ahead and used a spring and heavy extended buffer. Thanks for the response.
@@armaspecusa appreciate the feed back I switched back to the C weight . I’m gonna go from there. I’m using a BCM mk2 14.5 upper in my experience c or h work and with the info you’ve given I feel C for this is the smarter move at least starting out.
I'm running these in all my ARs, love them
Thank you. Glad to hear.
Will you do a video on how to tune by cutting the main spring?
Is the main spring the skinny or fat one?
Do you make an adapter to work with the A5 system?
Which one feels the most like the JP SCS?
Great product , I’m running the SMB in a 10.5 AR pistol and it’s amazing !
By any chance did you run it suppressed ?
@@mid305 unfortunately I can’t afford a suppressor. Maybe in the new future if it’s still an option
Yo, what caliber and what buffer weight?

I would try the H first and if it's still cycling to aggressive try the H2.

Yes they sell spacers 3 per package.
Compatible with rifle length AR15? if so which one.

Thanks for reading.
The SMB can be used in Mil spec buffer tubes. if you are running an A5 or Rifle buffer tube you will need a spacer we sell on the web site.
Thanks
Better customer service a phone number would make everything better
And products that are available and made to actual specifications.
I cancelled order after endlessly waiting and would probably avoid the brand all together
So if i want to do a direct replacement for a milspec ar which weight do I pick ?
carbine
@armaspecusa I have a PSA Blem Ar-15 model. Which weight do I get for the SRS and SMB? Thank you!
Barrel length? Caliber? Subs or supers? Suppressed? Gas length system? All of those are important to determine buffer weight.

I have an SBR 10.5 300 blackout I run a h2 buffer tube, would I switch to a ARMASPEC smb h2 ?
correct. with the SMB run the weight you currently have. If you run the SRS system go down in weight.
I have a 300 blk 16inch barrel which one should I get ?
Should I use the buffer retainer pin or no? Looks like the retainer pin will eat up the rubber ring . But I really don’t even know how to take it out.
you can use it with or without. But we recommend removing it.
It just sits in there with a spring underneath.
Pull it out with needle nose pliers.
@@hansblitz7770 thanks for the reply. But from what I’ve seen you have to take the buffer tube off in order to get it out.
I have the arm253-bb can I just change the weight I needed the h3 not the bb or do I have to buy the other complete one?????
The BB and AR-10 can not be changed. You need a new SRS in H3
How backed up is shipping still? Order placed well over 2 weeks ago & no tracking numbers.
Same but finally got it after like 3 weeks
Same here. No shipping notification still...
3-5 days quickly turned into 3-5 weeks…
Took 5-6weeks to get mine (this is like 10days ago )

Ah Nice lol. I thought you were rotating the clock so 12 was 3 on a right hand gun. Let us know if you need anything else.
What are some of the provable benefits to this system Over milspec?
Smoother recoil, more firm chambering in adverse conditions, less noise.
The only thing completely provable would be the noise reduction.

I’m looking at running SRS on 12.5” 5.56 and 9” 300blk both full time suppressed. Anyone have best guess on weights? Was leaning towards carbine since they say to drop down weight. TIA
That should be good to go on 556. I would probably use the SMB on the 300blk with H weight.
I run the H weight smb on a suppressed 12.5" 556 rosco barrel and it works great. Definitely smoother than a normal spring setup.
Has anyone run SMS on 10.3 AR pistol with suppressor and what weight do you have on it?
SRS I would run H. with SMB you could probably run H2 depending on the ammo.
Which one to run for a 9mm PCC?
Our 9mm offerings
Where's the link to buy them? Can anyone link me pls
just "google" armaspec
Which one will work with an ar9?

They have a specific model for the AR9. Just look at their website. You'll see it in the drop down when you select your buffer weight.
@@LV_223 I think I have the 9mm one
I'll get around back to it sometime. Went ahead and used a spring and heavy extended buffer. Thanks for the response.
Mine sounds horrible in my gun way worse than the spring! I've tried everything to fix it so I'm going back to the spring! Sad
Did you lube it liberally? It should sound super quiet. I have one in a MK18 and it is buttery smooth and quiet.
Shit I just battled to get the h weight on my srs because that’s what I normally use now I see this and the c was good enough? Dang lol
Yes we recommend springing down one. And the SRS is best with suppressed guns. But if the H runs fine stick with it.
