Great Bolt Carrier! – The Microbest Bolt Carrier is made from high-grade Mil-Spec materials and manufactured using precision machines.
When I received my bolt carrier, I was happy to see that the gas key used Ned Christiansen’s OCKS to secure the gas key. Additionally, I gauged the bolt shoulder, gas ring, and bolt tail and was happy to see that the carrier was gas efficient.
I will definitely come back and get another one in the near future!
#1 in the USA for 24/7 support. – I emailed the manager at 10 pm. He responded back within 15 minutes. This company takes care of their customers.
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.
