Complete Nickel Boron Full Auto Bolt Carrier Group 300 Blackout BCG – Recently purchased this bcg along with a sledgehammer charging handle and not only was it easy to install myself but gave it a much cleaner look for my 300 blk out pistol. Haven’t taken it out to shoot yet to test it out but when I get the chance I hope to be pleased with the results. Lastly the fast shipping and well packaged items were appreciated!
items were appreciated!
sound of freedom – This was a great set up. I loved being able to customize the set up. Only issue I had was my own fault as a newb to building these. I used a heavy barrel in a slim hand guard. It makes adding attachments tough with clearances. Hoping someday to also get an AR10 from here.
