hello guys! i've been amazed after reading "the holy grail of building your aeg dmr" and well i decided to try my own project
so i have a combat machine m4 (363mm barrel) and i was hoping to make it into a dmr.. i'm limited to 400fps and a pretty tight budget... probably no more than $100... any suggestions on what upgrades to get? as of now i've only decided on a tightbore and the SCS nub.
