Battle arms is a great company. The bcg is quality and already comes staked. Finish is nice. I ran 500 rounds on my rifle with it so far and have zero issues. I would buy another one on my next build.

I have not had a chance to put any rounds through my rifle yet so I don't have any info on how the BCG operates but the craftsmanship is right in line with all other parts from the this company. Will update when I have put some rounds through it.

***Update from my previous 2 star review for poor customer service***I have previously sent them a picture of the BCG in the original package that I still have and did not see a response. I sent message to them on their website and they responded saying that they had replied and requested original proof of purchase. It took a month on my end to respond. I had to track down the receipt and sent if off on February 2nd, 2022. As of February 8th, 2022, no response and I sent another message asking if there is anything else needed on the 8th.I have dealt with several firearms companies and this is the least desirable experience I have had.

I purchased this BCG and out of the box I inspected it and took off the factory lube. The finish was quality was not disappointing at first glance and have high confidence that this is a quality BCQ regardless of my less than stellar experience. While disassembling, I found that the firing pin retaining pin is difficult to take out. The milling on the hole for the firing pin retainer pin was milled too small. I sent a message on Battle Arms website to advise them of my issue. In that message I advised that the firing pin retainer pin was extremely hard to remove and it required pliers to remove. Below is the response email I received several days later."The tolerance for that pin is supposed to be tight. This is to keep it from walking out during the vibration caused by firing.Proper removal is to use the tip of a bullet or small pointed object like a pick to leverage the head upwards and then once you can grab it to twist and pull at the same time.The procedure is reversed for insertion and requires you to twist it back into place to fully seat it again.Sent by Battle Arms Development using Odoo."I have since tried responding to the email and it does not allow replies. I again sent a message on their website and am waiting the several days for a response. In my second correspondents with Battle Arms I explained that I am a Colt Armorer and have worked on hundreds of Colt M4 rifles and have not experienced this issue. We will see and I will try to update this review.
