Here is one you don't see very often - the MechTech Carbine Conversion Unit. CCU.
These are made to use with different pistols. This one is 1911/9mm.
The complete pistol frame is slid onto rails on the bottom of the housing, and secured in place with the slide catch.
This one was acquired used. It was very accurate, but prone to stovepiping. Different ammunition, different ejectors were tried without success, and it was packed away. Time passed, and eventually MechTech was contacted. There was an ejection problem with 1911/9mm units, and a new boltface insert had been developed to address the issue. Once installed, the unit ran like a top. And as mentioned, it is accurate. Other CCUs made for the Glock, etc. didn't have the ejection problem. If you search, you will be able to find Hickock45 demonstrating them.
Originally, the butt was a piece of flat strip steel. A new housing was installed with the fittings for a M-4 carbine type stock.
Some details:
Function of the pistol portion is unchanged, except the slide catch doesn't catch anything. The action can be mechanically locked open by pushing the cocking handle sleeve in.
The bolt assembly extends forward and around the barrel. The recoil spring is an extension, not a compression spring.
Stripping the upper unit requires an Allen wrench and the following of instructions. The screws securing the barrel block and forend grip are removed, and the barrel and bolt are drawn out to the front. Keep the recoil spring under control! Cleaning can be accomplished without disassembly, apart from removing the pistol frame, which is very easy.
As I mentioned, the CCU is accurate, and very comfortable to shoot.
The pistol frame is restricted, so this applies to the assembled carbine. Barrel is 16".
The Leupold 1X Prismatic suits the carbine very nicely. Most any reflex, dot sight or low magnification scope would be appropriate.
The muzzle unit is decorative, non-functional.
