80% Single Shot question

[NPC_Tank]

Sorry if this is redundant thread but I looked and the only things I could find regarding single shot stuff was with regards to purchasing them from Shops...

I have three 80% lowers from Tactical Machining that are in line to be milled out... (eventually as time provides...) My question was this. If i wanted to make an AR pistol "legally" you must have a lower that was DROS'ed as a AR pistol and not rifle. If I am completing this lower with the intention of registering it as a pistol will I run into any problems legally? Originally I bought these with the idea of buying an upper or two that have their own source of magazine and did not use the normal magazine that the AR15 has. An example would be the AR57. If I wanted to buy a AR57 12 or 6 inch barreled upper to make a pistol... yes one with only 10rnds and something I could shoot legally here in CA without getting in trouble with anyone... you know ... all that about them thinking an upper that is shorter than 16" is a SBR and all...

Just want to play by the rules and avoid getting in trouble... Please if anyone knows anything about this LMK.

Thanks everyone

Anybody?

once you complete the lower, you can let it be a pistol or a rifle, up to you, no registration required.

Say for example I am caught with a 6 inch barrel upper (which would be for this lower)... how am I to prove that the upper is for my Single shot lower and not a SBR if its not "on record" anywhere as being deemed/DROS'ed one. That was my question in a nutshell I suppose... Thank you for the reply though.

"I think", to be safe, you might want to finish the pistol lower first, then buy the pistol upper and keep it attached to the lower.

Thanks for the reply man. I was going to do just that.. anyone else have any ideas?

Funny, I just posted something up on the gunsmiting forum regarding a single shot conversion, or single shot sled. I too am interested in putting together an AR pistol.

Keep the gas system off at first so it's single shot...
When done you do not have to register it unless you want to..
You can put the gas system on later and make it a semi...
But you cannot have over a 10 rd mag ever and must have a bullet button..

presence, or lack thereof, does not make it a single shot. Plenty of SSE pistols are made and sold with functioning recoil/extraction systems. Its a single-shot if it can only hold one round of ammo.

The AR57 is blowback operated, so there isn't a gas tube you can disable. As mentioned above, you need to build it with a single shot sled initially and then it can be used with CA legal mags.

Build the pistol lower to 100%. If its the only ar lower you have you can get the upper ahead of time, if you have lots of rifles you should probably hold off on getting the upper until the lower is done. When you have it done and complete, volreg the single shot pistol. Now it's registered as a pistol and you can make it a mag locked semi auto...

I agree with you I guess I was not thinking enough on that... Thanks for catching that.

Thank you everybody for the replies! I have a couple AR's (A stag and a Black Rain Ordnance) and a bunch of 80%ers. I only have one completed 80%er at the moment which will being anodized some time next week if all goes to plan. I just got in a Single shot lower (80%) which is why I brought up the legality issue here. Thank you all for the help everyone :-)
