[ARCHIVED THREAD] - PSA 5.56 Premium Full Auto Bolt Carrier Group - No Logo - Shot Peened HPT/MPI Bolt Carpenter 158

Posted: 4/16/2017 2:57:47 PM EDT

I am looking at this PSA bolts assembly Cat 39339.
I looks perfect from a specification point of view and its $89.99.
Any thoughts or recommendations?
Thanks

I have several of them and have never had problem with any of them, the Premiums should be made by Toolcraft, I have one that has over 30K rounds on it, with no problems at all.

Gtg. GREAT BCGS. Carriers are Toolcraft made, bolts are undisclosed thus far.

I have 2 that run issue free.

Toolcraft nitrided BCG from Monmouth Reloading, 79.95. Got one a few weeks ago. Fast shipping.

Love my Toolcraft BCGs.
Monmouth has them at a great price.

I've also been fairly impressed with Right To Bear as well.

Gtg but come heavily soaked in cosmolin so will require good cleaning and lube job

Thanks! I just ordered. I went with the PSA because of the 158 Carpenter Steel and HPT/MPI

None of mine have come with cosmolin on them, I normally just wipe them down and put a few drops of oil on them and shoot them

Same. Drop it in some Mobil 1 and wipe it down. Run it wet.

My 7.62x39 bolt is PSA. No issues with it so far, from a caliber that is known to punish bolts.

Mine has been trouble free, NiB coated PSA BCG.

Just to be clear, I'm fairly certain the only difference is the better coating (Nitride) on the Toolcraft, and the test results on the PSA Bolt (HPT), with PSA is selling theirs $89.99 and Monmouth Reloading is selling the ToolCraft for $79.99.

redtruck90: Thanks, looks like you are right. The PSA I am referring to is simple phosphate finish. By the way, the Toolcraft bolt (alone) looks very nice as well and is well priced @$52.00. Toolcraft states they make over 6,000 bolt carriers/week! Impressive.

I have about 1000 rounds on one of mine. I have had to replace the gas rings and that is it. No problems at all. GTG.

They good, run it.

Can anyone confirm that these particular BCG's have a bolt with the MPI/HPT markings? Just wondering?

I have one of their premium BCG's with logo, stock #8779, and it has the MPI/HPT markings on the bolt.

8779 is the bcgs I buy there...Premium hpt/mpi and PSA logo marked.

Hard to tell from their site on the other cat. #

Mine (PSA Cat. 39339) just came in. The bolt barrier is bone dry, the bolt somewhat lubed (the whole assembly needs a good lube).
They look gtg for me and I am very satisfied. The Bolt is HPT/MPI marked as on their website photo.
