Fast shipping, excellent customer service, will continue toorder from PPrimary Arms
Good product, good price
Good looking product, staking could have been a little bit better. This was my first purchase from Primary Arms. Excellent shipping, good communication. Very pleased and will buy from again.
Perfect for the Price!
Got it on sale for $109 for my new built; took it to the range and what a difference. Runs and cycles without issues and very smooth operation.

Great product fit perfect would highly recomend
Have run this BCG in my RRA LAR15 for years so when these went on sale I jumped on one to complete an upgrade project on my 20+ year old EA-J15 which is now range worthy again.
High quality product, slipped right in. Can run without lube (I ran 500 rounds just to test it out and it ran fine), and wipes clean with a cloth. Extremely fast shipping, and great price. They cost more straight from FailZero and this is the lowest price I've found. I'll never use any other BCG's in my AR's.

I bought this for a new SPR type build I have not yet installed it but it looks to be of good quality. I will report back once I get to use it.As always PA was quick with the delivery. Keep up the good work.
