G3 pistol part kit question

[moto.x]

Hi all, are we allowed to purchase a G3 parts kit? I'd like to build a pistol but I'm not sure about the legality of a G3 parts kit.

You sure can. Or a SBR.

Parts is parts, a wise man once told me...

I see fair enough, would I be able to build a G3K as a pistol? I'd like something like the PTR K3P but with out the rails.

You can build a pistol or SBR.

I think you're fine legally. Sourcing or bending the receiver may be the tough part. I'm a bit interested myself. Do you have the receiver figured out? Barrel?

I like the PTR stuff but I think they only make them in 8in versions now which is a bit short for a 308 in my opinion.

What about just building a G3K with a 16” barrel? The shortened bolt carrier won’t interchange with a regular one.

Ken,
Good info!

So, the pistols take a shortened bolt?
Different receiver also?
I know little about the pistol versions of that platform.

I think the SBR route is the best way to go. I have a receiver. My plan is a 15.9” barrel. An extra $200, but I’ll have the gun I want.

Correct me if I’m wrong, but why couldn’t you register a SBR and then put on a 18” barrel. It would still be registered as an SBR. Or is this one of those MD confusing gun law loop holes?

Good question. I don’t know

Found out. No. If you put an 18” barrel on it, it is banned….lol.

Yes, that rod portion of the bolt carrier is shortened for the shorter cocking tube. The G3K uses a 33 length cocking tube. The really short pistols are based off the HK51 builds using basically an MP5 length cocking tube.

SBRs partially falling under the state definition of a handgun is what keeps them out of the enumerated banned assault long gun category. The state definition of a handgun is barrel under 16” or something like that.

I guess you could do a G3K consisting of the 17.7” full length barrel, but 33 length cocking tube and bolt carrier.

Forgive my ignorance, I'm just now getting into HKs. I thought I just needed a standard G3 parts kit, a G3k cocking tube and G3k barrel? Where did I go wrong?

Im going for a clone of the G3KA4 which uses a 12.4" barrel. But in pistol version.

Whoops, I remembered incorrectly. The G3K uses a regular G3 bolt. The cocking tube support is shorter to allow the G3 bolt to fit in a shorter tube.

Guess you’re set.
