Well, thanks for all the input guys, I got some help with it at Stumpy's Custom Guns in Swansboro NC. Turns out that they milled a couple thousands off of the inside of the bolt carrier. It functions perfect now, I do like the Velocity trigger and have one in a long range AR-15 with a 24 inch bull barrel. As to the small carry handle, I have looked for the AR-10 model and have yet to find one. It shoots accurate out to 150 yards which is all I have to work with at my friends' farm. Too many trees and brush in eastern NC. Sorry it took so long to follow up. Keep your powder fellows, you never know when we might need it. Tony

Hello, new member here with my first AR 10, this the quote from gunbroker where I purchased it "Custom Matrix-Aerospace AR-10 Rifle Matrix Aerospace custom Upper & Lower receiver. Barrel match 16” Armalite 7.62 MM NATO CR-MO CL 1x11.25 Matching Armalite bolt carrier CMMG Lower Parts kit MK3, 308 15 Round Armalite magazine Armalite free floating forearm. Armalite Flash Hider ATI Stock and hand grip" Now my problem is the rifle refuses to cock after firing..it feeds, fires, extracts, ejects, feeds, and nothing. I can manually cock with charging handle without ejecting the new round. Then it fires, and same thing happens again. I pulled the CMMG lower parts kit and installed the Velocity 4 lb steel case trigger and an ambidextrous safety lever and its acts the same when dry fired. If the trigger is pulled, the hammer does not reset, if the trigger is released, the hammer resets. Can this be a bolt issue? It's the only thing that touches the hammer, could the grip screw be too long and mess up the trigger? Help! Thanks in advance.
