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
what does PA-15 Engraving mean on the bolt carrier group ?
bfet62 on Apr 2, 2019
Is this BCG entirely made in the USA?

Awesome Nickel Boron BCG
Being my first Nickel Boron BCG, I was thinking for the price that for some how I wouldn't be pleased with the overall quality. But I took the chance anyway. I was very impressed when it arrived. the look, feel and action cycles smooth, and clean up is not much more than a wipe of the rag. I bought Mothers mag & aluminum polish thinking it was going to be dull, it was not, it even came oiled. I am so glad that I made the purchase.

Excellent BCG with amazing price!
The Toolcraft BCG performed very well. Shot the first 500rds with 0 fails. Then ran another 500rds the following week without cleaning or lubing, with the same results. 0 fails

Smooth action
This was my first NiBor bcg, and I was very pleased with the overall quality, look, and feel. The action cycles smooth like butter, and clean up is not much more than a wipe of the rag. I will be picking up a few more of these for other builds.

Smooth as glass
You can feel how much smoother the bolt is simply by charging the rifle. The NiB finish is stupid easy to clean and has had 0 feeding issues so far. Can't beat it for the price

Other than being slow on returning the new part it's been a good experience
Reason I'm giving this a 3-star review is because the Machining process toolcraft apparently try to bring it out of the milling machine to quit and cut part of the lower rail off bolt carrier group just waiting for Palmetto State to return a new one they were very fast on get me an RMA to exchange it but just a slow process of doing so and receiving the replacement bolt carrier group

Great bolt for the price.
Bought this bolt wanting to upgrade from PSA's standard parkerized bolt. Oiled it up and dropped it in, and it easily runs twice as smooth as the standard. I have shot several hundred rounds through it and so far have had no issues.

best is have see and almost any price point.
if i could give 6 stars i would!!! this is a crazy good bolt. the finish is mirror like and and machining is very good and the edges feel Hey ben chamfered. I remember when I got out of the military in 2004 a bolt like this would cost about 250 to 300.
