So just got a new KP-3 in, but the feedneck was replaced with a feed off a 68 magnum. Feedneck's loose so I was thinking about getting a new feed system. I'd actually prefer a spring-fed over a DF, and I happened to have a couple of the Spec-Ops longbow mags lying around and got to thinking. Do you think it'd be possible to mount a rail around the slot in the body to accept the reciever for the Specops mags?
Pics are kind of crappy, but you can see how the reciever mounts on a rail, directly over the slot for the feedneck.
