ken e on Oct 2, 2018
BEST ANSWER: Yes, based on the profile of the BCG..
If I use this to replace my existing PSA BCG, do I need to have headspacing checked? Should it just work?
GAdog on Sep 29, 2018

Will it work on the 224 Valkyrie?
Gataor on Sep 28, 2018
BEST ANSWER: Yes and No... The carrier will work but you'll have to swap out the bolt itself. You need to use a 6.8 SPC bolt to use it with .224 Valkyrie
On this psa logo'd nickel boron 5.56 bcg is the bolt stamped with mpi and hpt ? Anyone notice ? Thanks
Ken W on Dec 8, 2018

Will this BCG work with my Panther Oracle 223/556 AR 15?
Joe M on Oct 2, 2018
BEST ANSWER: Yes it will.
So this bcg will definitely work with the 300 black out??
Trucker on Nov 29, 2018
BEST ANSWER: Yes, the bolts are the same for either 223/5.56 or 300 AAC Blackout. Generally, if bolt and barrel are new, headspace should lock up correctly. But a new bolt in old barrel or vice versa, better check for proper headspace.Enter

BEST ANSWER: Yes, I have it on a 10.5 pistol

Will it work on the 224 Valkyrie?
Gataor on Sep 28, 2018
BEST ANSWER: The carrier will work but you will have to swap the bolt out with one fitted for the 6.8 spc, it’s the parent cartridge of the .224 Valkyrie.

Well machined BCG
The purchase was straightforward and without complications. The BCG is the perfect BCG for my new build. I’ve been to the range twice and ran about 250 rounds without a hiccup. Thanks.

Once again...
PSA provides top notch quality at a price-point other companies wouldn't even imagine. Staked perfectly. Came lubed - but I took that off and frog lubed it. BCG ran great and once again I just love PSA!

Very good BCG but staking of screws is not very good.
BCG runs very good and cleans up easy. I knocked off one star because of the staking. It was not done well, I had to restake it because one screw was loose and required more dimpled stake.

Awesome quality.
Put it into a PSA I'd been running their stock freedom bolt in. Just wanted something easier to clean. Shoots great and takes seconds to clean. Everything I coulda asked for.

Top drawer
My son, son-in-law, and I built guns as a pre Christmas activity. These BCG’s have all of the most desirable features. They are good looking and just drop dead rock solid. All three guns performed well and were quite easy to clean up after our sight-in session. IMHO you put your money into the BCG and the barrels for the best results. You can spend some crazy money if you want, but I’m not sure that you can do any better than these BDC’s.

after about 3,000 rounds, my gun show cheepo bolt was causing many malfunctions. someone recommended this bolt and carrier, so i ordered one. 1,500 rounds later i haven't had a single malfunction except those induced for training.

Own 2 of these and will purchase again for next build
Fired 150+ rounds through new build without a failure. This bolt is in a 223 pistol build.

I use Gibbs lubricant after cleaning and it runs smooth and looks good.

Great value on a sturdy BCG
Bought this for a 300 BLK pistol build. Always amazed how little carbon is on it when I clean the gun. Works flawlessly and I plan to buy a few more.

Great BCG
Top of the line for the price! I've compared this one to several other NB BCG at twice the price, you can't tell the difference. No machining marks, smooth and very slick. A little EWG and you will have a hard time holding onto this one. Very pleased with this purchase.
