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!
