I知 not planning on breaking any federal laws. I said in my second post that it would be registered on an ATF form 4 (I actually made a mistake, it will be on an ATF form 1).
I have done my research. NFA weapons are not new to me. I already have half a dozen silencers, a machine gun, and 40mm grenade launcher. To the best of my knowledge there are no federal laws preventing either of us from doing anything we want (except for manufacturing a new machine gun). You can make a long gun in to a handgun, or a shotgun into a pistol or anything you can dream of. You can have it in any configuration, with any barrel length, mount a grenade launcher underneath it, and top it off with a silencer. It痴 all perfectly legal; or I would have been in federal prison a long time ago.
I知 actually thinking now of buying (as others here have suggested) a TC Encore pistol receiver for my project. As coyotejoe said, it is made to be a pistol. I need to look at available holsters or Encore pistols since I壇 like to have that option. I think that this is my best bet.
I guess I値l send this extra H&R receiver in for a .357 mag barrel and make up another silenced .357 mag rifle.
I値l keep you guys posted on the TC forum of my progress. As of right now I知 thinking stainless TC Encore receiver on a form 1, with two 8 inch barrels, one in 12ga and one in 20ga. When all the cutting is done I値l hard chrome the receiver and barrels including the bores. Might even do screw in choke tubes.
Thanks to everyone for the help. More to come!
