Nice over all fit and finish - RISE Armament RA-1010 AR-15 Low-Mass Bolt Carrier Group (BCG)

Over all on my 300 blackout it's been great but the extractor springs were already no good on the new bolt. I am going to replace the spring to see if that fixes the issue. The bolt work3d ok on .223 and 5.56 but the 300bo It had a lot of failure to extract. I swaped to one of my other bolts off one of my 5.56 and it worked flawlessly. It has to be the bolt in some way fingers crossed it's just the spring as it seems weak.
