I just finished up a trigger guard for my Talondor. I made it from a piece of aluminum channel with only hand tools. I wanted to be able to use an AR15 grip and stiffen up the frame to eliminate any flex. After completing it I primed it with Rustoleum aluminum primer then Rustoleum truck bed coating. I think I did pretty well.
Really nice, I also made a pair for my condors, I live in Mexico city and “AR15” is a dirty word aroun so no (AR15/M4)parts can be legaly obtained around here, I mill the trigger guard and made the stocks of leftover wood stipple it and finally painted, photo shows left condor (.30 cal)done and the right condor (.25) in the process, supressors are also DIY projects and they work fine
