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: No this will not turn the AR into a full auto. You have to add an auto sear to the lower reciever. However if youi do this you will risk jail time and and a hefty fine ffrom the ATF. All full auto weapons to be legal must have an AFT Form 4 tas stamp. The advantage of the full outo bolt is the weight. It assists with smoother cycling.
Will it make my M4 automatic?

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 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:

I'm very new to this but could you tell me if that includes a firing pin?
Michael K on Jun 5, 2018
BEST ANSWER: Any complete AR-15 Bolt Carrier Group (BCG) from a reputable seller includes a firing pin & firing pin retainer. PSA BCGs are excellent. I have several in use and have no complaints.

My bcg has performed perfectly out of the box.
I have seen smoother bcgs and a couple that were rougher.
I wanted a sturdy part with a durable and corrosion resistant finish, in other words a mil-spec bcg and that’s what I got.
I’m happy and would purchase another for a future build(s).

Gritty bolt. Not good.
The carrier was excellent, the bolt was terrible. Even sent it back for replacement and they sent me same one back all lubed up. Finish was horrifying, looked as if it was left in the parkerizing solution for way too long. Felt rough like sandpaper to the touch, gritty as all get out. I do not recommend this product if you need a complete BCG. It was on sale and cheap enough for me to keep carrier and get a different bolt from another mfg but I will never make this mistake again.

Great BCG
Advertised and priced as BLEM but no blemishes were found. Fits and functions well, no failures on initial run of 100 rounds. PSA items have proven reliable at a reasonable cost. Can not say that about some other brands, even some that are quite pricey.

Good quality mil-spec part
I picked up two of these and both run great. I find little difference in performance with these compared to several of my other OEM Colt BCG that I own. Machine work looks good as does the staking of the gas key. I would have preferred they didn't come with the logo but it's not a huge deal. PSA makes it a point to explain in the description that they will arrive bone dry however mine were drenched in oil! Personally, I would rather see them covered in oil during shipping and storage to prevent rust or corrosion. No records were set in regards to shipping speeds but I'll live with the wait for the quality and prices that PSA has been providing.
