AR-15 Pistol Build Completed

[browningguy]

Well all of the parts finally arrived so I got everything put together today, will get down to shoot it on Monday.




Yankee Hill lower with CMC lower parts group and CMC drop in 3.5 lb. straight trigger, BCM Gunfighter 3 grip and I used an end plate with single point sling mount on each side, and an SBA3 brace to finish it off.

The upper is a PSA 10.5" 7 twist with Mbus rear site, Sig Romeo5 red dot, Magpul MOE handguard, old Surefire G2 that I replaced the bulb assembly on for a 1300 lumen (vs. 100 lumen originally) output mounted on a generic Mlok light mount. The linear compensator is a Kaw Valley, I've noticed a decent muzzle blast reduction with them on my 16" AR and my PCC so thought it would be better than a regular flash hider.

It's heavy for a pistol though, 7.1 pounds with a 30 round mag loaded.

Nice build!

Looks like FUN!!!

Nice looking build. I watched some videos of those AR "pistols" being shot on YouTube and they were shooting them from the shoulder. I can't figure out how those are a pistol and not a short barreled rifle? But as long as its legal have a blast with it. No matter to me.

I shot a Hipower 9mm with shoulder stock and loved it. I don't see why those are considered illegal myself. It didn't seem any more deadly than a common semi auto handgun. I don't understand some laws.

Long story short, the ATF determined that shouldering an AR pistol with a brace does not reconfigure the brace into a stock. Since a brace is designed to allow fire with one hand, shouldering it doesn't make it a stock and thus an SBR. Here is the full letter. Emphasis on paragraphs 3 and 5

Thanks for that. I hadn't seen that before. The laws that make a short barrel gun with a buttstock attached seem silly to me. I shot that 9mm hipower with a buttstock and thought it was great. IIRC those are a Canadian made gun and since they came built that way they are legal. So why the regulations on other short barreled guns and rifles? They aren't used in crimes. And if someone wants to commit a crime it a simple matter to shorten a stock or barrel with a saw. Clyde Barrow did it to several of his guns.

I have a Crosman 1377 air pistol and they make a buttstock for them to turn them into a short barreled pellet rifle. I put that buttstock on there several years ago and never want to take it off. What a handy little gun that made. A 22 pistol with buttstock would make a great survival/backpack gun.

Be very careful. The ATF is making reverse decisions on what are legal braces. Do not let anyone film you shooting a brace from the shoulder; it is not currently illegal, but if the anti gunners win expect radical departure from normal jurisprudence. Look up honey badger and the ATF

I built this one for the wife- she found my A1 a bit too heavy.

PSA generic lower with a PSA 11½" upper, and a Trijicon MRO.

It ran 100% from the first mag to the last. The brace began to collapse (get shorter) during fire, so I might need to upgrade to something with fixed positions, but for now I just smoked the set-screw down. Definitely needs a better trigger though, even she commented on it.

I put a Rise Armament Rave 140 in my 10.5", and SWMBO chose it as her new HD gun:


She does quite well at 25 yards with it. First time she's ever shot an AR.


I feel better knowing she has something she's confident using and shoots well.

I recently jumped into the AR pistol game and I'm glad I did.


Then I added a little bling

 

[Choctaw]

OP, well done on your build! My latest is rather generic but it seems to be working.

Ahh.... one of those AR-14 thing!

Yup, says so on the other side

the LaRue triggers seem to be very nice and are inexpensive. Not light enough for a match trigger, but still a very good all trigger.

You mean like in that top picture in post #9?

 

[Fine Figure of a Man]

I don't understand some laws.

Probably because you aren't dishonest, irrational or insane.

I have that same lower sitting in a box waiting for the right upper to come along. I'm thinking a 12.5" 350 Legend.

 

[GunnyUSMC]

I would say that you did pretty good on your first pistol build. The only thing that I would change is the pull tab on the bottom of your Troy Magazine. I found that they tend to get snagged on things.

This was my first pistol build. Not long after building it, I added a pistol brace and a hand stop.


I built this one for a friend.




Now you need to build one in 9mm.

A buddy here at work got a hankering for a 350 Legend to take hog hunting in Texas in December. He ordered a PSA lower and a Bear Creek upper yesterday. I'm kinda hoping he lets me try it.

I cannot wrap my brain around this thought of people being filmed. The constitution expressly bans ex post facto laws which in this sense essentially means that the act is currently legal and cannot be prosecuted if it later becomes illegal. In addition if it is illegal it cannot be altered to a higher state by judicial changes after the fact. So, the law of the land exists, and until changed it is the law. Once it changes then there is a clean break point. Laws goes into effect at midnight on X date. Anything before is a moot point and anything after is fair game. The only issue with ex post facto in this situation is that the law of the land is open to interpretation and reinterpretation without judicial change. Essentially laws are established by congressional act and BATF rules are established by a magic 8 ball deciding what to make of various arbitrary mandates and regulations

I am not a lawyer and I do not play one on TV. Seriously firearms laws literally make no sense and are mostly against provisions of the constitution and Bill Rights, but do not count on that keeping you out jail.
I know that if I ran a commercial range I would have surveillance cameras going for purposes of liability. Such has been discussed at some of the clubs that I belong too.

I wish that an AR pistol topic could come up that didn’t turn into a legal debate. It really turns a good topic into a rather boring topic.
Oh, BTW, there’s a Legal section on the forum.
