I'm new to this, this CM was going to be my first build but did a 223 to get my feet wet before diving in.
This was a DPMS build kit from Moriarti armaments, the upper was a completed one--didnt want to get into all that yet. The 22" SS fluted barrel is from ballistic advantage. Not sure about the BCG. The lower is an 80% which actually sparked the build,,i just had a feeling Pa. was going to jump on board with Va. ( they did, and hopefully that went away for a long time). Milling with the 5d tactical multi platform jig was fun ! Im hooked.
I have two issue with this build.
#1 the bolt catch wont catch the bolt ( so i guess at this point its just a lever) The pivot action of the lever doesn't have enough travel to go high enough to catch the bolt. I either have to mill out a little in the lower or take off a little of the lever's backside. OR there is another lever i dont know about out there. Im sure others have had this issue, hope someone can help out.
Empty mag doesnt activate it either of course.
#2 I placed A zooms in the mag to see how it cycles ammo. Pulled the charging handle and left go, went to pull it out and it was stuck. Had to put it on the floor an push down with both hands and came out. You can see in the photos there are markings on the bullet and shoulder of the cartridge. I figure that has something to do with it, none of my other firearms does anything like this. The scrapes in the bullet can easily be felt as is the one in the brass. I ran a camera up in the chamber to see if there was a burr or any signs of why this would be doing this but didn't see anything. I oiled up the A zoom and bolt parts that would possibly be a problem. It got to where i could get it out with one hand but it was very tight. Any help would be awesome
