Not as good as other Bolt Carrier Groups that I have purchased from PSA and very expensive shipping
This is the 4th Bolt Carrier Group that I have purchased from PSA. Screws in this one were not staked as good as they should be but I can fix that. I used to be able to order parts from the PSA website and pick them up at a local PSA store to save the shipping costs. Not anymore unless I order a complete firearm. Shipping cost is now $8.50 from the other side of town to my house. I also have to pay South Carolina tax because I live the state where PSA is located. This will probably be my last on-line order from PSA.

bad quality control
purchased this bcg to finish a build. works and functions however it is scratched up and beat up. there's tool marks and scratches all over. hopefully this bcg will last and not fail prematurely.

Finish on bolt assembly marginal
During last few weeks I've bought 4 bolt carrier groups. Previous 3 are excellent finish wise. The last was not the premium BCG but fully tested unit. Nothing wrong with it except finish looks like black oxide and faded. I'm sure it is fully functional and appearance will better with a coat of oil. I recomend buying the premium BCG over this unit as you will be much more pleased. If you are on a limited budget this BCG will get the job done though.

This is a good BCG
I now have 500 rounds on this BCG and its been perfect no failures. This is a quality product at a great price.

For the price you cannot go wrong here.
Just be sure to do a disassemble when you get it clean it and do a good lube job on this BCG. It was gritty for me and I don't like that. Aside from that I would buy another one.

Works as it should
Zero problems on a 300 Blackout pistol with an Anderson 10.5" upper. The only reason I gave it 4 stars for quality was a small rough gouge on the carrier that looked like it happened during machining. It was not in a vital area and a pass with file took care of it. First time at the range went through 200 rounds of Remington 120 grain without a failure. Would definitely purchase this BCG again!

Works well in new 300 Blk Build. Finish and fit very good to excellent.
Used this BCG in a new 300 Blk Out build. Fit was very good. Good finish chromed areas are excellent. Staking is very good firing pin very good finish. Worked 100% with 150gr Supersonic and 220gr Subsonic. For $79.95 and free shipping IMO it was a real bargain much better than some other basic BCGs I have had/seen. You could easily spend double or more than what this cost for a higher end BCG. It seems to be good quality for a milspec BCG. I could have given 5 stars for quality but since I only have 100 rnds on it I don't know yet how it will hold up. But finish is holding up well so far.

Refuses to go into battery with PSA Freedom Upper
Purchased this for a PSA Freedom build I was doing. After thoroughly cleaning and lubricating both the bolt and the upper I assembled it. This BCG simply will not go into battery without me hitting the forward assist or using the scallop. I have tried racking it and using the bolt release. It just sticks right before battery. Even while firing it refuses to cycle completely. Unimpressed.

Comment by PSA: Your PSA upper and BCG have a lifetime warranty against defects. If you have an issue please contact Customer Service directly for repair or replacement.
