I have 2 of the new Rhineland Arms MP5 SD 10/22 kits, so I left one alone and kinda re-worked the other one.
It won't appeal to everyone, but I really like it. You know me, I like to share

I added a M4 style stock....it just screws in.

I added a Rail on the bottom of the forearm

I added a G27 grip (alot of work....arghhhh)

I added a cap for the end of the shroud (it covers about 3" of the barrel, and there is holes in the shroud......Jr. ATF agents..relax)

And the bolt-ons.....Aimpoint clone, front and rear folding BUIS's






And never fear...this one is still in-tact as well.
