Non-reciever machine guns

I'm aware of Lightning links and RDIAS for AR-15s, but what else is out there?

HK Sears, FN Sears and M2 carbine conversion kits come to mind of what I have had or fired of friends.

The HK sears only work in the 90 series roller lock HKs (HK91, HK93, HK94 etc.).

Are the M2 conversion kits themselves the registered part on the rifle?

Yes, they are.

Sort of. They work in all of the HK roller locked guns, not just the 90 series guns.

Oh man, that's a sweet looking piece of hardware. Damn you William Hughes.

Tittle II M2 carbines can be a registered receiver, registered part (the trigger housing was always a nice touch to form 1 in the old days) or a registered kit, often with one part having the serial number and that is the part you can't replace. The HKs are similar .....

Sort of. They work in all of the HK roller locked guns, not just the 90 series guns.

The majority of German HK roller lock guns came in as the three common HK90 series guns (i.e. 91, 93 and 94) plus the SP89 (only one short of ninety ;-) and now days there are a lot of US made "clones" including Mike's MM23eK in the photos. "90 series" and "roller lock HKs" are really close to the same, just trying to separate from the newer "AR" based HKs. I think we are both in the same chapter if not on the same page.

Yes, they are.

Depends, there were several ways to register M2's.

Question, where can one go to see diagrams, or possible videos of how an automatic weapon works. Anyone know if public library would have literature on this?

There is tons of stuff on youtube and elsewhere.

Skip to half way through and there is a diagram.

Some Uzis were done as "registered bolt" guns.

Interesting, so was the bolt altered in any fashion in the conversion?

Yes, they are slotted to clear the bolt blocking rail and milled to clear the barrel restrictor ring, both items are present on a semi gun to prevent an SMG bolt from being used.

What HK roller lock gun isn't 90 series ?

Good catch and there might have been some trigger pack or sear Uzi's ... but don't know what got forced married later.

What HK roller lock gun isn't 90 series ?

Maybe a SP89 or HK21e/HK23e .... however, I have always lumped them in.

There are also some registered Uzi sears around. They are the least desirable as far as the Uzi family is concerned.

 

[alfahornet]

Yes, the full auto bolt was slotted so that it would fit into the semi receiver without the need to removed the bolt blocking bar that on the right sight of the receiver.

I am guessing you are looking at a "system" gun, which is limited to two and a half choices, M16 based, HK based and Uzi based (half choice since limited to pistol calibers).

The uppers on the M16 based is lower cost, some question if you can use the parts in the larger 308 receiver "AR's (legal not technical), however, more choices for belt fed uppers, in particular in 308, in the HK and for subguns the MP5 is a little nicer IMO than a M16 9mm.

There are other variants that are not 90's numbered guns. I'm aware of a 33 and a 53, plus the above mentioned belt-feds.

I guess I should've clarified that the sears are not limited to JUST 90-series MARKED guns, but also with the other HK roller-locked guns.

THe 32's, 33's and 53's are mostly custom-made guns produced now, not your typical stuff you can buy in a gun shop.
