Is this a full auto bolt?
Donald C on Apr 16, 2018
BEST ANSWER: Yes, rear under cut is M16 full auto.
Will this BCG function with a .300 Blackout upper?
Ron P on Apr 18, 2018
BEST ANSWER: Yes, a 5.56/.223 bolt will work with 300blk being that 300blk is based off the necked up 5.56/.223 case. So bolt, mags and lower are interchangeable, just different barrel.

John C on Dec 30, 2018
BEST ANSWER: Just turn it around backwards and it should work fine for left-handed uppers. Where did you get your left-handed upper?

Kevin F on May 28, 2018

I have recently purchased a PSA-15 5.56 pistol. Will it fit in my AR pistol?
(just want to make sure it is compatible in a AR pistol setup.)
Thank you.
Tim H on Jul 22, 2018
BEST ANSWER: The receiver is no different for an AR pistol than for a rifle. What makes the difference in an AR pistol is the manner in which the receiver is originally stocked. That being the case, there are no changes made to either the upper or lower receiver that would require a different BCG than is common for a rifle. That being the case, this BCG will function properly in an AR pistol chambered in 5.56.
Will this work in a DPMS Oracle 5.56?
Huntindad80 on Jul 10, 2018
BEST ANSWER: Absolutely! Best buying decision I have ever made on a BCG. Quality is excellent, well worth it. I use my old BCG as a backup and this is now my primary. Smooth as butter!
I see that the bolt is listed as a full auto, new to an AR platform, must I fire in full auto?
larry I on Feb 10, 2019
BEST ANSWER: Full auto bolt just means that it is mil-spec. Some manufactures cut the underside rear off the bolt to make it unable to be used for full auto firing. This bolt could be used in a gun that was capable of firing full-auto, provided it was accompanied by full auto trigger group and auto Sear. Unless you have those parts, and a stamp from the government, your gun will NOT fire full auto
Does it work with piston driven actions?
Andy H on Jun 20, 2018
BEST ANSWER: This BCG will not work with piston system.
I have one of your nickle Boron .223 / 5.56 bcg already for my .223 . Great bcg. Will this bcg work with 300 blackout as well ?
Tim C on Apr 30, 2018
BEST ANSWER: Yes, any standard 5.56 / .223 BCG will work in your .300 blackout.
Can this work on 224 Valkyrie?
Said S on Dec 28, 2018
BEST ANSWER: No the bolt face is larger in diameter than a 5.56 bolt. .224 Valkyrie uses a 6.8 cartridge that's necked down to .224. The carrier is the same, however the bolt would not work with .224 Valkyrie.
Is this a semi auto or full auto bcg?
Randy J on Dec 12, 2018
BEST ANSWER: Full Auto.
J
semi Auto application ok?
Nathan on Sep 18, 2018
BEST ANSWER: I have this BCG in four AR 15's semi auto's with no firing or cycling issues (about 500 rounds per rifle).
Can this be used with a 223 wylde barrel?
Zion R on Feb 15, 2019
BEST ANSWER: I have it on my wylde 11 in barrel and it works great. Get some steel wool as it shows every spec of carbon fouling. I also notice I have to clean it every time I shoot it. Crud gets in there deep if I don't. So don't sight rifle for hunting trip and not clean it before you go. I do lover the clean look. I run one on my .300 blk pistol as well.
Witch bcg is better? This one or the PSA one? I think the PSA one has a better bolt right?
Jason S on Jan 2, 2019
BEST ANSWER: They are essentially the same except one has a logo and the other has a nickel boron coating. The nickel boron has a less porous finish and is easier to clean and maintain.

Can anyone tell me what the difference is between this bcg and the other nib bcg?
Jay K on Jul 20, 2018

Awesome BCG. Highly recommend.
Love this bcg. I don't have to run my AR wet and it cleans with just a wipe off a towel. I have these for all my rifles.

Can't beat this BCG
It would be really hard to find another comparable BCG for this price and quality. I have purchased 4 and could not be happier. Can't really find a reason not to have a few extras. BTW, bought a Lantac BCG from another vendor and while it was new, scored the ramp area in only 21 rounds of M193, Maybe I just got a bad one but this has not been an issue with these PSA Premium NiB C158 groups. Sent the Lantac back after not getting a response from their Product Manager. Thank You PSA for great products, service, and support!

Works well
This BCG is a very nice addition to my rifle. It looks great with an all black rifle and I’ve not had any issues firing
