9mm AR

[Pyzik]

A 9mm carbine is on the want list. Looking forward to what you come up with.

Thanks all... as much as I'd like a new, complete gun - that's out. As is a dedicated 9mm lower, simply due to cost. I have most of what I need so I'm trying to keep the cost down. Truthfully, I wonder how much she would use it, even as much as she says she'd want to. She has a hard enough time with my .22 pistols, she can't rack the slides on my Glocks... health issues SUCK. Pretty much anything she has will be a bench rest shooter anyways.

But the info on the barrels and whatnot helps... I have some reading to do, and maybe some more work with the wife on what I have, to see what might be possible. Maybe I can talk her/me into the dedicated lower from Quarter Circle... that would be awesome as it looks so much better than a standard AR lower with the block installed in the magwell.

9mm ARs aren't exactly low recoil. The rearward recoil isn't too bad, but the forward recoil from a heavy bolt and buffer slamming into the rear of the barrel extension can be pretty jarring. If it's just a fun gun, I'd look at a .22 over a 9mm.

9mm can be kind of finicky as well. You may have to tune mags, adjust your mag block, play around with different buffers, etc. I'm using a dedicated CMMG lower and Metalform mags. All of my mags had to have the follower adjusted.

Other issues, the 9mm bolt likes to break bolt catches. There's a lot of over travel present in the 9mm, so it gets a good running start on the bolt catch and will snap it in half. You can either use a longer buffer to limit the over travel or a spacer behind the buffer. A stack of quarters works well.

If you use a non ramped bolt it can be harsh on hammer pins. And with the non ramped bolts you have to make sure you're not using a notched hammer. Ramped bolts are pretty common these days though and they're much easier on the hammer pins and allow you to use pretty much any hammer.

well nuts... she was reading over my shoulder and saw the recoil mention. Now she's not so sure. Have to find some reviews and/or videos.

If not just go 22lr u can get a 4.5 inch barrel add a suppresor and your done

found a few pis and videos

IME the 9mm AR recoil is harsher than the 5.56, although neither are particularly bad. But if your wife's issue has to do with the recoil, I'd be looking to go as light as possible on a 5.56 and try to tune out the recoil with adjustable gas blocks, muzzle brakes, etc.

A Sig MPX is on top of my list as well. I'm going to order a factory SBR shortly.

I was planning on getting a pistol and then SBR'ing it in the future, but given the current state of Form 1's in WA I'll probably also just order a factory SBR. Probably not until next year, though. Still need to set up a trust.

[SwissyJim]

yeah, things are on hold for her... typical indecisive women (LMAO). Says she'll play with my M&P15-22 more, so I'm going to use the funds to redo and reorganize my optics between the rifles. Plus I get my PewPew lower back to plan something with

Whoa!! That site is awesome!

Thanks!

I will say this out of all the rifles I have and have shot.. my wifes UCWRG build has the lightest felt recoil and little to no muzzle rise. It comes in at right at 7lbs. This could be lightened up with a different rail and optic (currently sports a 3x9... I know I know you can flog me later). The down fall is that the Phase 5 muzzle brake is the loudest thing I have ever heard and the concussion off it actually makes me nauseas. I can literally feel my internals shake around every time she pulls the trigger. I know there are tons of other brakes on the market that show the same results but this is the only one I have experience with. Would love to get my hands an a lantac dragon with a shroud and compare it. But she wants nothing to do with changing what she has.

Yeah I got a dream sheet made up for one of these as well :)

Jim,

I'd just build her a SBR .22LR upper and call it a day if she doesn't like recoil. That's the direction I'm leaning towards on my wife's gun.

However, you should still build a 9mm for yourself.

I've been reading up on the M&P forum... I may get another M&P15-22 and SBR that. I have a standard one and love it. And a 9mm for me is probably my next build, but before that I am going to completely redo my optics between all my guns as I'm not totally happy with the route I took to this point. Now that I have a few more rounds thru my guns, I can correct the misconceptions I had as a 'new' black rifle owner and make them all sing that much better for me.

What direction are you going with your optics Jim?

[SwissyJim]

I've got mostly PA red dots, and one EOtech. My plan is to get a 1x4 or 1x6 scope for the 6290, put the EOtech and magnifier on the Tavor, get a COMP M4 for the 5.56 SBR for battery life/SHTF fun, and put the red dots on my 300BLK SBR, M&P15-22 and 10/22. And probably a fixed set of irons for the 458Socom upper. Maybe something different for the 300BLK, not sure. Since I plan to try and take it caribou hunting, probably another 1x4/6 scope - but with a good mount I can swap the 6920 and 300BLK with a day to re-zero it. As I get older, my astigmatism is really playing hell with the red dot stuff... altho the EOTech is not bad with glasses for some reason. However the PA dots are getting to be not as much fun but should be fine on the .22's for what I use them for.

Also as I get more of a higher round count under my belt, my ideas on distance, ammo, targets and so on, the choices I made initially (red dots, magnifier) are not quite cutting it. Now, if the red dots were crisp and sharp to my eyes, the dots would be good. But since I see them as more of a small drop of jelly all smudged out on the edges of the glass, I'd like to sharpen things up. That, and I've always had hunting guns and optics until the black rifle bug bit me, so I thought the red dots were the 'tacticool' thing to have. Well, yeah, but... practicality is now starting to win me over. I like my hunting scopes and I'm good with them so I'm going to incorporate that into my builds, and since they are sharp to me, why not go with what I know.

Just need to soak up some OT to pay for plan A. Plan B is just to wing it as I have been and try to snag a good deal here and there
