Rise armament bcg - RISE Armament AR-15 Bolt Carrier Group (BCG)

I needed a new BCG for one of my rifles and decided on the Rise Armament BCG Black Nitride since it was in the price range I was looking for and I know Rise makes quality products. The first one I received came broken as it was missing a gas ring, was very lose and failed the gas ring test. It also looked like it seen 10000 rounds due to all the carbon build up and how dirty it was. I RMA'd it and OP sent me a brand new Rise BCG within a matter of 2 days (excellent customer service) and this time I received an actual brand new BCG. The tolerances were tight and it passed the gas ring test with flying colors. The staking on the gas key were excellent too so I decided to throw it in the upper that was in need of a new BCG, took it to the range and shot 200 rounds flawlessly. I am glad I waited to write the review; until I got the new one. Let's say I was not thrilled with the first one I received and would not even attempt to put it in any rifle due the condition it was in. I think I received a broken and used BCG by mistake the first time but the second one was perfect. I would definitely recommend it and would buy it again. Thanks OP for coming through!
