Wow! That looks pretty sick! I might have to do that with my longshot! But that would mean lengthening my under-the-bed defense against marauding little bros... Maybe I'll get the recon
. In terms of the forgrip, CaptainSlug did a nice job of making a cheap and easy pump. You could get the same result with 2 pieces of wood a couple of nuts and bolts, and a slot cut near the front of your rifle...
Cheers!
