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: 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 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....

Will it make my M4 automatic?
Little Joey on May 27, 2018
BEST ANSWER: Only if you have the shoulder thing that goes up. Also, it may require you to make pew noises to jump start ot.
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"
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.
Does each part in this Premium BCG meet or exceed mil. spec.?
jay G on Jun 7, 2018
BEST ANSWER: Much better than "mil. spec. I have bought @5 of these...They are great....
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.
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: Yes, this assembly includes the Firing Pin, the Firing Pin Retaining Pin, the Bolt and the Bolt Cam Pin.

Cody P on Aug 21, 2018

jonny on Oct 14, 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.
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: From my understanding the Clot SP1 is a unique BCG . SO no. THIS BCG would work with any a full auto M16 or M4 lower. If you had the bucks to buy a full auto gun.
Is this better or as good as the Nic. Bor. BCG?
Titt. on Oct 15, 2018
BEST ANSWER: the C158 NiB version is easier to clean after use but feature wise, they are nearly identical.
fwiw: PSA offers 3 different NiB bcgs.
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: Works flawless in my ballistic advatage as well as my anderson uppers. If your aero is mil spec, should work fine.
Does this include a firing pin or will that need to be ordered separately?
Jon C on Oct 9, 2018
BEST ANSWER: The firing pin is generally considered as part of the BCG. Simple answer: 'Yes'.
...if you look closely, you can see the tail of the pin in one of the photos.
Is this the same BCG that comes in the PSA Freedom upper?
EricB on Nov 16, 2018
BEST ANSWER: Looks like it to me
Is the firing pin shrouded by the bottom of the BCG or is it exposed?
Jeffrey P on Nov 16, 2018
BEST ANSWER: Shrouded. Excellent BCG and great price.
Can I get this without the logo?
DeanM on Nov 1, 2018
BEST ANSWER: who cares?
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.

I only run semi-auto, so I can't comment on the functionality in a fully automatic firearm, but so far it has worked fine for me.

This Bolt can be used in a .300 blackout or a 5.56 upper. Full auto or semi, it will hold up to any thing you can throw at it.
