I started a DL-21 build today. I bought an old charter arms ar-7 receiver from a gun dealer, and a real sterling grip. The receiver was missing the barrel nut, so I found one online. I also have a magazine on order.
I fiddled around a bit with how to attach the grip, and I finally settled on using a piece of threaded rod with some crafty geometry to line it up with the bottom mounting hole in the grip. I added a coupler nut and a black socket cap screw so it could be attached from the outside. For the barrel, I just took a piece of pvc pipe and tapered it down a bit towards the end. I’ll finalize that a bit more once I get my casting of a 2” mortar fin, unless I find a real one! I have a single point scope replica on the way and picked up some reasonably similar scope rings and a dovetail rail. I’ll post more pics as I get more parts and work done!
