Guns'n'stuff

A lot less expensive to shoot tho!

I have 2 1903 Springfield (one with a hunting stock), 1909 Argentine Mauser, .30-30 Winchester, .303 Lee Enfield, 12g Mossberg pump shotgun, .357 mag revolver.

Ok, so AR15 SBRs and pistols get around barrel length restrictions because the little nub sticking out the back is a "stabilizer" not a "stock", right? And there's nothing stopping me from putting whatever I want on the back once it's been sold to me as a pistol or SBR?

I'm looking at this setup:

The same company sells a stripped lower for $40, what else would I need to make it a complete weapon? Magazine and trigger assembly?

They'll also add an 80% lower to the pistol kit for the same price. I'm off to Youtube to see if that's something I want to tackle myself, or if I even can without a proper mill setup.

Here's a good link on the "legality" of SBRs ( https://lockedback.com/easy-legal-way-get-sbr-short-barreled-rifle/ ). Yes, there isn't anything to stop you from adding whatever you want after you've purchased the gun. I imagine someone, somewhere has gotten in legal trouble for modifying their AR pistol into a SBR w/o paying the stamp fee.

Based on the first link you posted, all you'd need to make it complete is a machine lower receiver. Machining the lowers is pretty easy, more so if you have the jigs and a mill. You can machine them using a drill press, just takes longer.

I'm 87.8% sure I've got access to a mill up here, just need the jigs and cutting tools.

To answer my own question, yes there is.  Apparenlty it's only a "pistol" if the stabilizer on the back is left unmodified, and apparently in the ATF's opinion, doing anything to make it more convenient/comfortable to shoulder counts as modifying it, as does putting a rifle stock on it.  And even if you don't modify the stabilizer, firing it from the shoulder is a grey area that the ATF has issued multiple conflicting opinions on.

So I guess legally speaking, what I want isn't an AR pistol.  What I want is a short barreled rifle, because I want an actual shoulder stock.  That requires a permit/tax stamp thingy just like a silencer, and that defeats the purpose of the 80% lower.

Decisions.

I don't disagree with you. But, with all the AR parts ordered around this country what are the chances that someones notices you ordered an AR pistol barrel?

I know that suppressors have the stamp you need to by. I just did a quick look for barrels are their doesn't appear to be any restriction from ordering whatever you desire.

That's sketchy in the current atmosphere though. I'm sure nobody is paying much attention to what parts get ordered by who, but there's kids out there inspired by this March For Life business who are basically SWATing their classmates, finding out somebody's dad has guns and reporting them as suicidal or a shooter threat or whatever. I'd hate to have one of Ian's friends sick the cops on me and have them find a felony in my gun cabinet because I hadn't bothered to take the shoulder stock off after the last shooting session. That wouldn't end well for me or my family.

I completely agree. These are strange times...

Ok, so tell me more about lowers, Brady. I know you need a different lower to shoot .308, but I don't know why because you can shoot .300 AAC out of a .556 lower, can't you? Will a .308 lower shoot anything besides .308? What about 9mm, you need a specific lower for an AR9 right? Can you shoot any other cartridge out of a 9mm lower?

You can shoot .300 AAC out of the 5.56 because they share the same case. I believe you can shoot 7.62 out of the .308 case, but I have to check. According to google, the upper receiver is the biggest difference between a .223/5.56 and a 9mm gun. I'll have to do some more reading, it's been awhile since I've looked.

Oh, case size not bullet size. Duh.

Hmm, this guy says you can go 9mm with a barrel and bolt, so the lower shouldn't need to be changed at all. https://www.gunmann.com/ar-15-9mm-conversion-kits/

Looks good. Any reason besides cost you'd go 9mm over a .223/5.56?

Just trying to figure out how many firearms I can get in one . Right now I'm thinking one 5.56 upper/barrel/etc in carbine or rifle length, and then a shorty in 9mm for a pistolish thing. I like the idea of another setup in .308, but that'll come later.

Especially since somebody just made me buy a dropper post and set my slush fund back to zero.

That's the beauty of these "scary" guns. Super easy to pop a couple of pins and swap the uppers.

Then there's this: https://www.polymer80.com

That's not bad at all!!! At that price it might be work picking one up to test the polymer lower out.

Kinda what I was thinking. They say the jig is only good for three lowers, but at that price it's disposable anyway.

This is a good deal though, if a fella doesn't mind a number on it.

I just pulled the trigger on one of these: https://palmettostatearmory.com/psa-7-5-5-56-nato-1-7-phosphate-6-m-lok-classic-sob-pistol-kit-5165449219.html.

Still haven't decided what to do about a lower.

Link is broken...

Take the period off the end.

Don't put periods there!!!


Looks like a sweet deal. Might as well just pick up a lower and start shooting especially since PSA has some around $60.

Davidson Defense down in Orem has a polymer 80 with jig and bits for $59.99 that's really tempting, if I decide I can tolerate an FDE lower on a black gun.
