excellent
Came in a nice hard cardboard tube. Stamped both mpi and hpt. Ive heard these are made by FN. So far approximately 7000 rounds amd still going. Normal wear marks and have replaced the gas rings twice. Gas key staked very well and the chrome looks good. I got this when on sale for 69$and its just as good as both my bcm and toolcraft bcgs.

Disappointed
The price is fantastic and the material itself appears to be well made however I have been having issues with it cycling. The bolt seems to lock up and I am unable to pull it back without dissembling the upper from the lower receiver. One friend thought the gas rings may be too lose causing excessive friction while another thought the tolerances were too tight. Safe to say I am disappointed in this BCG because it does not function correctly. Gun smith here I come...

Fit and finish excellent!
I bought last week on sale 69.99 free shipping how can you go wrong at this price for a full auto bolt very impressed with quality and packaging I have yet to install or test fire I'm sure based on reviews it will run flawlessly I will mate it to my Anderson lower and the psa upper wich I plan to order soon thank you psa for a great product!!

It even has the PSA logo on it for once!
This BCG is perfect for anyone that is starting out and is willing to CLEAN there rifle after every shoot. If you are NOT going to CLEAN your rifle after you shoot. spend the extra money and get one of the higher grade finished BCGs

I purchased this as the combo deal BCG & Charging handle.

I have a half dozen orders with 20 plus items from PSA. Two snags to date But well worth the savings!
Customer Service is acceptably OK! It can take a few days to get a reply some times.
(There staff go to appointments and take vacations just like the rest of us!)

Low quality replacing immediatly
Bolt locks into rearward "locked" position in carrier when not in battery and refuses to move causes failures to feed eject etc. Very unsatisfied with this low quality product. If this is the "Premium" product I would hate to see what the regular bolt carrier group is like.

Good price-free ship-works great
I just received my PSA BCG (8779) yesterday. I did a complete cleaning as per instructions. I had it apart so I applied FrogLube. I apply FrogLube to all my guns. Try it you will like it. Tested the headspace with a go gauge in a PSA upper. All was good test shot today-worked as expected. Happy with both items.

Excellent
Had a lot of issues with extraction with the bolt that came in my rifle (Not PSA) had a lot of catastrophic failures on the range... I wasn't betting my life on my rifle I tried different types of ammo nothing new extractor pieces got me to about 70% reliability. SWAPPED THAT BOLT FOR THE PSA PREMIUM BCG AND IT FUNCTIONED FLAWLESS. Thank you PSA this product has made me confident with my rifle and your BCG ate any type of rounds that i put through it like a monster. I am 110% satisfied with it.

Very nice
Ordered on Friday morning it was delivered the following Tuesday. Finish is great. I can't wait to get my dissapator upper to run it in.

Good Product
Palmetto State Armory sells good products at good prices but their customer service is awful and if you make any mistakes in the ordering process they will make you pay dearly.
