If Kavanaugh gets confirmed and I combine this with a 40 or 60 round magazine, will I cause a rift in the space-time continuum?
BillyBadassBgRg on Sep 11, 2018
BEST ANSWER: Yes, but the rift will only occur if you use a 1:7 twist barrel and premium ammunition that exceeds 3000 fps at the muzzle. I may have to recommend at least an 18 inch barrel to ensure velocities that will disrupt the time-space continuum under stated conditions given this formula: f ′ = 2 π ℏ ( E ′ 1 − E ′ 0 ) = f ( 1 − G M R c 2 )
Will this bolt turn my ar into a full auto gun? Or what else would I need to make that happen. New to this and was just curious thanks!
Mckay B on Apr 13, 2018
BEST ANSWER: absolutly. ALSO, I understand that taking out your buffer spring will help your bolt carrier move much faster back and forth. It would also help prove you shouldnt own a gun faster.
Will it make my M4 automatic?
Little Joey on May 27, 2018

Looking to replace factory tiger ar556 bcg with a full auto bcg for reliability and fast firing. Will it work?
James H on Apr 14, 2018
BEST ANSWER: Where do you guys come from? Just funny to read some of the questions. You got no business with a MSR.
will this also work with .223 wylde?
edge1916 on Apr 16, 2018
BEST ANSWER: .223 wylde, is a description of a chamber profile...It is not a caliber of ammo....This BCG, will work with.. .223...5.56mm, and .300 blackout ....You do have to have a different barrel, for the .300 blackout.....all the other AR-15 parts will work with all 3....
Can I get this without the logo?
DeanM on Nov 1, 2018
BEST ANSWER: Yes, The part number is 39339.
Will this work the same for 300 blackout as well as 556?
Madison B on May 13, 2018
BEST ANSWER: Yes, a 5.56 BCG will work in a .300 (Obviously, use a .300 barrel.) The rest of the AR can use standard 5.56/AR parts. Check out this article on alternative AR calibers:
Check out Pew Pew Tactical's read on "Best Alternative AR-15 Cartridges and Calibers"

Who makes these carriers and bolts? Thanks
Mandrin S on Aug 21, 2018
BEST ANSWER: The largely subjective, but widely accepted answer is Toolcraft. PS has brought a lot of companies in to the fold over the last few years. As they are not publicly owned, there is no way to know for sure. That being said, I absolutely do not believe PSA would try and and claim that a bolt was HPT/MPI when they sell so many that aren't. Point being, who makes it is irrelevant so long as it's a quality product.
Question Would a fotech echo 2 trigger work with my current bolt carrier or do I need buy this auto bolt carrier?
Mitchell B on Sep 19, 2018
BEST ANSWER: This totally depends on which echo trigger you have, the early version required a special bcg that was notched and the new one just requires a plain fa bcg.

Titt. on Oct 15, 2018

Are these checked for correct headspace ?
Raymond B on Sep 27, 2018
BEST ANSWER: Head Spacing is specific to your barrel and the bolt. You will need to check it with your barrel receiver. Most if not all New Barrels and New Bolts will be fine.
How does this differ from a standard bolt carrier?
Gavin E on Oct 22, 2018
BEST ANSWER: it doesn't. same thing.
Can this replace just a normal semi auto bolt carrier. I'm getting deep sc
ratches on my round when my carrier slides over the shell in the mag ?
Mike B on Oct 10, 2018
BEST ANSWER: Yes this can replace a "normal semi auto bolt carrier," although I suspect that if you're scratching your brass it may be due to.something else. I recommend you check your mag and mag release to ensure they aren't the issue before you replace the BCG.
Will it work with a semi auto?
MartyG on Nov 17, 2018
BEST ANSWER: Absolutely. Being a full auto bcg means it is designed to be strong enough and capable of being used in a fully automatic version also. I've used two of these in separate builds. And, they function flawlessly.
Do I need to buy a firing pin for this ?
Brian on Nov 21, 2018

Andrean D on Dec 1, 2018

Will this BCG or a nickel boron bcg work with 7.62 x 39?
Ronald P on Nov 26, 2018
BEST ANSWER: You can just use the bolt carrier with a 7.62x39 bolt and extended firing pin. Though i would probably just buy a dedicated 762 bolt.
Will this BCG work with my AR chambered in 7.62x39?
Michael G on Nov 19, 2018
BEST ANSWER: No it will not case diameter is different
Adding this BCG to a standard AR, will it be necessary to have an adjustable gas block?
Alberto M on Dec 8, 2018
BEST ANSWER: Nope, should work just as any other bcg does. Mine is in a pistol and does just fine
So I have a Aero Precision upper and lower. How well does this bolt work with other manufacturers parts?
Krazee M on Nov 16, 2018
BEST ANSWER: The AR15 is extremely modular. Quality parts from Aero and Palmetto will work perfectly fine together.
whats the difference between a full auto and semi auto bcg. Will this bcg work with either?
Jerry G on Oct 26, 2018
BEST ANSWER: Because this BCG is full auto it is a little heavier than a sporting or light weight BCG. The extra weight gives a slightly longer lock up time. Because it is full auto if you had a legal full auto lower you could use this BCG in that lower and it would be capable of full auto fire in that mode.The bottom rear ( front )of the BCG is not cut out.
Will this work in my Colt SP1 chamber for 223?
Tim M on Sep 24, 2018
BEST ANSWER: yes, colt sp1 or sp2... these fit and function great.
Is this better than the nickle boron bolt?
sheldon F on Dec 3, 2018
BEST ANSWER: I personally use the PSA full auto BCG's in all of my AR builds. I have never had a problem with them. I also like them because they aremil spec "military specifications". I know people that have the nickel boron and they have had no noticeable increase in functionality or reliability. I hope this helps. I believe this is a great deal. If I needed another BCG I would buy the PSA premium full auto BCG.
Is this legal in jersey? I’m building my own and I can’t gave a full auto gun here
Chris S on Dec 1, 2018
BEST ANSWER: A bolt carrier group shouldn’t be illegal but check with your in-state gun shop. I live in a different state, it’s not illegal for me to order gun parts.

Ok
The bcg itself is good the packaging was not so good, the first one I ordered came crushed from UPS, not PSA fault but they did just put in a bag to ship it. Customer service was okay. Got a replacement that had clearly been used but, it looks and feels good so I'll use it

Why Spend More
I have not once, had an issue with these BCG's They run like a top in every gun I put them in. They even are chrome lined. For the price you honestly cant beat this. You're getting mil spec, and I would consider these the cheapest trustworthy BCG period. I never have second thoughts about them. I like not stressing and fretting over questionable parts, and Palmetto has my trust here.
