The carrier was one of the $18 demilled ones off of gunbroker a while back. The top two carriers are the demilled ones, and the one in the middle is the one I made into the short carrier. I also used two recoil springs that could collapse over one another to take up less space. The mag in the picture above is a Bulgarian 10 round mag that was converted to use the straight walled cases and then blocked to reduce capacity to meet the hunting regs. The performance is on par with a 35remington with the same barrel length.
