Flawless

Everything you would expect from a $200 BCG for less than $100. Over 200 rounds on the first day and zero issues. Will update if it performs less than expected, but I don't foresee any issues.

Perfect

Updating my review. I've had this for about 7 months as of 3/06/19. I have about 800 rounds cycled so far with this BCG and I have not had a single malfunction. This is paired with the Bear Creek 7.5 inch nitrided barrel. Again... the machining and finish are perfect. Been recommending this BCG to everyone. Unless you want something really fancy or gotta have a specific logo, I see no benefit in spending more on other brand names when you get the same quality for less.

Will update if I have any issues but upon initial inspection this is a very nice BCG. Mine has absolutely no tool maks, the nitride is smooth and looks really nice. BCG is in spec compared to other BCG's I have. I'm happy with this purchase.

Awsome sales experience and great product

This item was an add on option to the Bear Creek Arsenal 16" Mlok 300 AAC Blackout upper assembly I purchased to add functionality to my home built 5.56mm AR. This is a melonited (Nitrided) BCG. After a day at the range, I came home and cleaned the upper. The melonite finish makes cleaning a very easy task. This BCG functioned flawlessly. I'm really impressed with the speed that Primary Arms had the upper with options delivered on my doorstep only 3 days after I ordered it.Great product at a great price. Thanks Primary Arms!
