Hey guys...
First post here, but this something I actually know about.
The Wise Lite Carbine is a copy of the Sterling Mk VI. It's similar in most ways to teh Mk IV's used for teh E-11's in ANH, but it has a couple differences (besides being semi-automatic only).
1) It does have a bayonet lug.
2) (and this is the big one), the muzzle cap is cimpletely different. In a Mk IV sterling, teh barrel is secured tot eh muzzle cap with two screws, that screw into a trunion on the front of the barrel (behind the cap). In addition, the Mk IV has a distinctive boss on the front for use in mounting the bayonet. The Mk VI (and the Wise Lite variant) doesn't have the boss on the front, and it has a wider opening for the larger 16" barrel. It has a large barrel nut which is used to secure the barrel in place.
Even if you SBR'd the gun (got all the paperwork, etc.)you would have to make significantt modification to the muzzle to get it close to accurate in appearance.
You COULD of course, simply remove the barrel, and modify teh weapon using "greeblie" attachments to get it to the correct appearance. This would likely make the weapon unusable as an actual firearm, but it WOULD make an outstandng base for a blaster. If you intended to use it in public, you'd probably want to ensure that it was obvious form a cursory inspection that it was no longer a real firearm (fake barrel tube or something.)
But beleive me... I've considered this approach.
