The gun in reference is an HK93

I do understand that C&P is just an aesthetic modification to fill the pin holes on a lower, however my question is why isn't there just a hole there for a regular pin to go through?

 

[ts160]

Normally a hole would be there and the shelf would not. The shelf is there so that a semi auto trigger pack has something to engage. Clip and pinned trigger packs give the look of a full auto to a semi auto.

Copy, so instead of clipping and pinning does anyone just make plugs for the holes?

ive never seen um listed i dont really get the whole pinned idea either causse its fake they sell usa made triggerpacks that do not have holes in them, might try your hardware store or carplace maby.

Plugs can be made from two pin heads, a little easier to glue in than the front end of the pin.

The reason why there isn't "just a hole there for a regular pin to go through? " is because ATF has deemed having the capability of affixing a swing down lower on this type of gun to be too easy to make into a machine gun and thus verboten.

Wow, that's another pretty dumb one there. I don't know much about these style weapons, but that seems too similar to an ar15 style gun and a hell of a different opinion.

Not sure I follow your comment...

On AR-15, the lower receiver is the gun for legal purposes. If you have a lower that is drilled for an auto sear, then it is a machine gun. On an HK, the upper receiver is the gun for legal purposes. You can have all the full-auto capable lowers you want. No problem. If the upper can accept a full-auto capable lower, then it is a machine gun. The shelf welded into the upper prevents it from accepting a full auto lower. The shelf actually occupies the space in the lower where the auto sear (and take-down pin) need to go. I guess you could in theory drill a hole through the shelf to accomodate a pin, but I'm not sure the shelf is really big enough for the hole. I don't have a gun in front of me. Either way, I wouldn't suggest taking innovative approaches to this stuff. It's not worth it.

Clipped is a functional modification. Pinned is cosmetic.

Hk roller locked guns dont have uppers and lowers. They have a receiver and a trigger housing.

Is having a clipped and pinned trigger group illegal?

 

[frogman342]

No.

Is having a clipped and pinned trigger group illegal?

Is having a clipped and pinned trigger group illegal?

No it is not illegal to have. UNLESS you've modified a full-auto pack to fit onto a semi-gun, then you've made an illegal machine gun. If you first convert the pack to semi-only, then it is ok.
