The build was a fun test on how well I could problem solve a decently complicated project. The buffer tube, for example, stuck out too far for me, so I made a modified version of the butt plate that is extended, and when I was ordering parts, Ohhunts ran out of gen 1 rails and I never realized how different gen 2 rails were, so I had to modify the locking block and spent way too much time filing. It at least fires sometimes! I just would like to figure out why it fires on safe and the trigger dies after every shot.
