Dedicated ar22 builds, who has one?

[Jem45472]

Beyer barrel, and cmmg collar came in today. 16.5" bull barrel weighs less than the 10.5" barrel it's replacing. Nice!




Last step is to order a new trigger. Gonna take the timney out of this for fear of light strikes. I'll be replacing it with a hiperfire hipertouch. Those are known to be very hard primer hitters with adjustable pull weights from 2-4 pounds.

 

[Jem45472]

Decided on which model hiperfire I'll be using, it'll be the hipertouch reflex (or the older name 24 3g). Surprised you don't really see much about these triggers. You have to do some digging in forums to find the people who use, and swear by them. They're pretty big in 3 gun I guess, and also people building anything blowback operated, and also for people using steelcase with hard primers.

They're pretty cool how they're cam operated allowing a 2 pound trigger to give a hammer impact that's 30% stronger than milspec.

But this is in the advertising, and the real reason I'm buying it!

 

[Jem45472]

Trigger bought. Found some on GunBroker for $175. Cheapest I've found.

And for anyone who may want to look into the hipertouch series, the eclipse, competition, and reflex are all designed the same. The Genesis, and elite are slightly different with some initial take up to the triggers, and different reset.

You hooked me @Jem45472. I just bought a cmmg 22lr bbl with collar and all the other stuff to build a dedicated AR15 22lr upper. Thanks a lot.

 

[Jem45472]

Addicting isn't it?

Surprised you found a barrel, I was having trouble finding a cmmg barrel other than pistol. Glad I went with the Beyer barrel anyways, it's nice and lite.

Trigger came in today, this'll make sure there are no light strikes.

 

[Jem45472]

@ArmedCorgi
You sticking with a milspec trigger? If not some triggers can have light strikes. From what I saw, most 2 stage triggers seems to be ok, but I wanted a lite single stage which can become problematic.

The one I bought above will deliver stronger hammer strike than milspec, and I've also seen that the cmc 3.5 pound drop in works.

I got to cheek out a DPMS 22 upper on a standard AR lower last week, really sharp looking rifle but damn was it heavy! Awhile back someone had the same upper on the board for sale at my Club I didn't know if I could make it work on my SCR so I passed on it.

 

[Jem45472]

Hipertouch installed. Very nice trigger! Works just like a compound bow, when hammer is about halfway through it's travel the cam and springs kick in sending that hammer home with force!

My scales not working, but with the Beyer barrel, this is very lightweight. Very glad I went this route. The optic is probably the heaviest part. Balanced very nicely also.

Yes this had a SS bull barrel that was at least 18" maybe 20".

Definitely too much for me, got a bad left shoulder and I'd struggle with that. This is a lined aluminum bull barrel at 16.5" weighing about a pound or less.

I haven't given much thought to the lower yet actually. I could build a new lower from a stripped one or just use one that is built with mil-spec trigger that I have on a build I don't use at all. If I were to throw the 22lr upper on either of my go to AR lowers, it would either have a Rise Armament drop in trigger or it will have a LaRue. I'd love to get a franklin armory binary trigger but those are mucho dollars that I need to use for a holosun 507k for my edc.

You should have jumped on it. If the dpms is a standard mil-spec upper it will fit on any AR lower and if the SCR takes any mil-spec upper, you'd be golden.

What I am cloudy on is how you get the bolt out. I see there is a set screw holding the collar onto the barrel, but the bolt slides hook into the collar.

Nevermind, I see the set screw is on the bottom, so accessable when the rear take down pin is out.

When I bought my timney he gave me a choice of the binary, or timney for same price. (Before that was a thing in NY) Looking back now, I would have taken the binary. What I'm really hoping for is the frt ridiculousness to get tossed. I'd love one of those in this.

I would totally be in on a binary if they were less money.

Parts for the upper came today. Will build it this weekend most likely.

I would grab yourself one of these pressure plugs if nothing else. Cheap insurance that the bolt carrier fits snuggly with no play.

I am pretty sure the rear of the bolt carrier would have had to be modified to fit on the scr. If you take a normal at upper complete with bolt carrier group the bolt will prevent the upper from locking into place.

Thanks, that's not something I would have wanted to get into! Plus I do have 3 10/22's.

 

[ArmedCorgi]

Finished the upper. Here it is on a lower I built a while ago.

While the bolt will work fine as is, it is very underweight for a 22. This can lead to several issues as stovepipes, light primer strikes, out of battery detonation, and heavy extractor wear.

This video convinced me to buy the adjustable weight kit from borebuddy, along with the users of frt, and full auto users who have theirs dialed in and running perfectly.

I would highly recommend it if you can spend a few more dollars.

I think I'm going to have to get that. I did only have one stovepipe, but the gas and spray was in my face and I'm sure it isn't good to breath that in.

Users reported it helps with that, and also keeps everything inside cleaner also.

I bought the adjustable, and have the steel weights in it at the moment. Wanted to test it this past weekend, but couldn't get out. They have a non adjustable version that would probably do you fine if you don't want to muck about with it.

If you get the adjustable, once dialed in, be sure to use a drop of locktight on the back plate screws.

I’m interested in the idea of building a fun dedicated .22 like the ones in this thread. I’ve never built a rig. Any “parts lists” or “build lists” that would get me into one for $500 or so? Seems like it would be a fun project.

Ar22 is kind of expensive to build from scratch, unless you have an ar or 2 around.

There's a bolt and mags for sale in classified section posted yesterday.

An ar15 can be built around 500 or so, then you can use the 22 bolt and it'll work fine, but groups really start opening up after 25 yards. If you want accuracy you will need a 22lr barrel, and the bolt collar.

Nothing hard or different about it really, just a bit expensive compared to a 10/22. You can also buy an m&p22 for cheap, but a lot of people don't like it's made from plastic, and feels toyish. But that's the cheapest way to an ar platformed 22.

Edited to add
4-$500 will get you the bolt, barrel, mags, and collar. Then you need the rest of an ar build, minus bolt, barrel. I'm guessing about an extra 2-$300.

I went all out on mine, and am probably into about $1200 or so

Yeah, you know, I can understand the calibrating and adding on it takes to make a conversion bolt that is supposed to work with a 5.56 bbl into a dedicated 22lr bolt. What I don't get is why there isn't a bolt group like the conversion bolt that is meant for a 22lr set up and isn't just gtg with a 22lr bbl.

I'm assuming they keep bolt mass light, and a bit harsh to work with all variety ammo, and barrel length/supressor choices.
