What's the difference between this Toolcraft NiB BCG and the PSA LOGOED PREMIUM 5.56 NICKEL BORON BCG - SKU 516446450?
SkipS on Oct 4, 2018
BEST ANSWER: I have both and they're identical besides the Logo. I own several Toolcraft BGC (.458 SOCOM, 7.62x39, 6.5 Grendel, 5.56) and this is the first time seeing their Logo etched on one.
How does the finish hold up?
Robert on Oct 6, 2018
BEST ANSWER: As long as you clean it, it will always look like nickle Barron. I have been shooting with this bolt for two years and it still looks as it did when I installed it.
Is this a full auto bcg?
shawn p on Oct 5, 2018
BEST ANSWER: Yes, has auto sear catch intact.
so this means the internal surfaces of the gas key is NiB as well?
Joe M on Oct 13, 2018
BEST ANSWER: The gas key looks grey/white inside, but not shiny like the outside.
Do these come from Toolcraft with the Nickel Boron plating or is the Nickel Boron added after they leave Toolcraft?
D h on Oct 12, 2018
BEST ANSWER: The TOOLCRAFT logo appears to be on the NiB finish, etched on the finish, along with "PA-15" on the bolt carrier only.
Is there any particular cleaners not to use on this finish, like Ballistol?
Brian L on Nov 14, 2018
BEST ANSWER: The only gun cleaners I suggest not using on NiB are heavy bore cleaners or copper solvent cleaners. As these type of products are very very strong and should only be used in the bore and chamber, and no where else on the gun. But any other CLP type cleaners/lubricants will not affect the NiB coating, ballistol included.
Will this work with .300 blackout?
BobbyC on Oct 16, 2018
BEST ANSWER: All 5.56 bolts will work with .300bko.
gerald s on Oct 14, 2018
BEST ANSWER: I don't think it is. Doesn't look like it.
Is the bolt NiB finished too?
Ruel D on Oct 13, 2018
BEST ANSWER: Yes it is.
Is it illegal to have a full Auto BCG in a semi lower?
Leeybarra92 on Nov 27, 2018
BEST ANSWER: No. The “full auto” designation pertaining to the BCG only indicates that it will function properly in an AR-15 with either a registered drop-in auto sear or an existing full-auto lower receiver. A full-auto BCG will in no way make an AR-15 fire full-auto by itself and is therefore
completely legal to possess by any person.
Will this assembly work in a psa 10 upper?
William M on Oct 25, 2018
BEST ANSWER: Absolutely NOT!! You need the appropriate AR10 carrier and bolt in the caliber to match your barrel (308, 6.5 Creedmoor, etc.). Big size difference in AR15 and AR10 BCGs.
Is the bolt an OEM or the bolt is made by TC and installed by them?
MichaelDiggs on Feb 13, 2019
BEST ANSWER: As far as I know it’s oem
does anyone know the full specs?
ALONSOZ43 on Apr 30, 2019
what does PA-15 Engraving mean on the bolt carrier group ?
bfet62 on Apr 2, 2019
Is this BCG entirely made in the USA?

Worth every penny and then some...
Using this in a 300 Blackout build and couldn't be more impressed. The NB finish is flawless and the rifle cycles
as smooth as silk. Look no further than PSA for a quality
NB bolt carrier group at this price.

Step #1 for your boogaloo build
Starting with the best bcg that you can buy should be the first step in any build. This is the only way to go. Toolcraft is known for making the best of the best. I haven't regretted this purchase. In fact, I bought 2 more for my brothers-in-law!
I could buy 87 of these things! Colonel_Angus
