2017 AR pistol thread (master)

[Ivleaf]

Hello. First time poster here. I have a couple of questions similar to Kelton's a few posts back. My upper is a side pull single shot. I want to use a standard 10rd mag fixed by an ARMaglock. Is that ok to do or do I still need to fix a Bob sled in place making it single cartridge manual feed. 2nd, I'm having trouble finding a 10.5" unported barrel. A friend told me that I might be able to take a ported barrel and to turn the gas block around. I don't think that would comply. Or does it? Thanks for your help.

Since your AR pistol is manually operated (straight pull bolt-action), it can legally utilize detachable magazines.

There's nothing that prohibits making a bolt-action single-shot pistol into a bolt-action detachable magazine fed pistol.
^Operating system did not change, only the ammunition feeding system and there's nothing prohibiting the change of the ammunition feeding system on bolt-action firearms.

So, legally a bolt-action pistol can go from a fixed 0 round magazine/sled that can not be removed without disassembling the firearm's action to a detachable magazine that is released by a standard magazine release.

2nd, I'm having trouble finding a 10.5" unported barrel. A friend told me that I might be able to take a ported barrel and to turn the gas block around. I don't think that would comply. Or does it? Thanks for your help.

Yes.

Thank you Quiet. Clarifies so much.

[Kelton]

Yep - helpful as always.

I may have gone overboard, but I built my pistol with a Bob Sled held in place using the Hogue Freedom Fighter kit (which is also what I'm using on my one "full-featured" carbine to avoid registering). It's good to know I can swap in a detachable mag. For now I'll leave it as-is since it's just a range toy for now... plus 458 SOCOM ammo is $$$ (even when I reload!).

Ivleaf, I contacted a manufacturer who made the barrel I wanted and asked if they could do one with the gas port started but not drilled through. It was no problem. So now I have something that can't possibly be interpreted as a converted semi-auto, but if I'm ever in a situation where I can convert to SA, I'll just need to drill and add a gas block and tube.

Hey Kelton. I've tried 3 different barrel manufacturers with no luck. Each said they were not taking custom orders or too busy to do so.
Could you tell me the name of the manufacturer you went to and how much you paid?

[franklinarmory]

In the process of manufacturing, we drill the barrels last. We could probably accommodate this request if there were 10 or more people interested.

[Ivleaf]

Bummer. My barrel was from Tromix. They specialize in big-bore, so it’s 458 SOCOM. Shot it for the first time on Friday. It was intense

Maybe a standard barrel plus JB weld? Or tap the gas port and put in a plug screw?

New Frontier Armory explicitly lists gunsmithing as a service, maybe try them?

Good luck!

Thanks Kelton! I found a company online that does custom orders with 10wk turnaround. Can finally get my build completed.
I just saw a youtube review on a 458 SOCOM rifle by Sooch00. Awesome! Diffinitely on my list of future builds. Thanks again

Ok. I'm about ready to purchase the barrel. One last question. Can the barrel be threaded so long as the pistol is in SSE2 configuration?

Thanks

[zeroman03]

IMO, it can. Since your build has to be in single shot configuration, the AW features that apply to semi auto pistols, one being a threaded barrel, will not be applicable to yours.

Threaded barrel is only a problem for semiautomatic without a fixed magazine.
SSE is not semiautomatic, therefore, not a problem.

If you do convert it to semiautomatic, then it will have to be fixed magazine since the magazine is not contained within the pistol grip, therefore, threaded barrel is still not a problem.

I thought that once a single shot is forever a single shot due to a redefine of "home built firearm"?

Also. I plan on vol reg'ing my firearm. Do I file it as single shot handgun or handgun other if it turns out to be legal to convert it to semi auto fixed mag?

[quiksilvern7]

I’ve been reading this thread for awhile now as well have been interested in building a 80% pistol. This is how I’d like to build it following what’s been stated in his thread please correct me where I am wrong.
80% lower engraved per ATF specs name,custom SN, location etc, also marked “pistol”
Pistol buffer tube, barrel greater than 6.5”, no gas block or tube installed
Sling shot sled, AR maglock installed.

Would this build be compliant with the new laws? All build steps would be documented and until further notice, it will not be converted to semi auto w/10 round mag.

The issue is debated. Some claim that the new definition still does not apply to modification of a completed pistol.

Some claim that it is now illegal to install night sights on a completed pistol unless the resulting configuration is also on the roster

Unfortunately, it won't "turn out" to be legal or illegal until after someone is arrested, tried, and convicted or acquitted, establishing case law. That could take years, or may never happen.

[Ivleaf]

Looks legit to me. Your lower does not need to be marked "pistol". Just make sure Cal: Multi is included in the engraving.
