AR-15, .22 WMR

Earlier this year, Bear Creek Arsenal began offering complete upper receiver assemblies in .22 Magnum.

I took a chance and bought one. It has been flawless for me, running on a PSA lower using their EPT hammer/trigger, which is a nickel-plated GI-style FCG.

Encouraged by that success, I recently received one of their 10.5" uppers in .22 Magnum, and it proved to be just as reliable as the carbine. Again, running with a PSA EPT hammer/trigger.

Ammunition tried includes CCI 40 JHP, and Fiocchi 40 JSP.

Both uppers provide good accuracy for me.

These are actually pretty cool. Did they come with the magazines too?

If they’d make this in a .17HMR I’d be all over that.

They come with one 10rd magazine (the black one), but Black Dog Machine also makes 14 round mags (the smoke color one). The uppers also come with a proprietary lightweight buffer and spring.

I have two ARs in .17 HMR, an Alexander Arms (blow-back) and a Garrow Firearms Development (gas operated). The Alexander has their own mags, but the Garrow uses the same Black Dog Machine mags as the.22 WMR

They are a lot of fun, too.

I've only had it for a short time, but it has proven to be accurate and reliable.

It is out of production at this time, but last I heard, Mike? Garrow has plans to bring it back.

Late last year there where some articles posted that Inland Manufacturing has licensed the Garrow design for 17 HMR and 22 WMR uppers. Production was supposed to start this spring, but here we are and so far no news. I've sent an email to Inland but have not yet received a reply. Inland Manufacturing is probably best known for their re-production M1 carbines, so they should have the capability and capacity to produce the Garrow design.

I went with the Tippman 22LR, as I have a WMR cylinder for my Bisley 22.

Had my pistol upper back to the range this morning with some of Hornady's Critical Defense 45gr ammunition.

No failures of any kind and accuracy was good. It shot a bit to the right compared to the CCI 40gr, but still on the 8" steel at 25 yards.

I was using it on an SBR lower that has a Rock River Varmint FCG, and no issues there.

Do you plan to try any 30 grain HV ammunition? I have been looking at the BCA uppers as well.

I don't have any of the 30gr stuff on hand and haven't seen it offered recently, so unlikely to try any soon.

Thanks for the offer, but I'm ok with the 40gr stuff.

There is another owner who posted this at RFC:

"...I tested the new BCA upper at 50 yds. The quality of the build appears to be pretty good. I tested 4 different rounds. CCI 40 grain hollow point, 40 grain full metal jacket, TNT 30 grain polymer tips, and VNT 30 grain polymer tips. I also bought extra 14 rd mags directly from Black Dog to go with the 10 rd mag supplied with the gun.

I had a failure to feed on round 7 of the hollow points. The nose deformed when it hit the feed ramp. With the high bolt speed from a straight blow back operating system this can be an issue. I switched to the FMC and the polymer tipped rounds. No issues. 100% reliable.

Out of the gate the accuracy was spotty. It would leave flyers. But as the round count went up, the accuracy improved. Must need some break in. For the final accuracy test, I couldn't believe how well the VNT rounds grouped. The Full metal case and TNT shot pretty well after the barrel settled down also. Maybe I got a good one or a good batch of ammo. Either way. it shot two groups of VNT in a row that were half an inch at 50 yds. Pretty good for a mag. I think Bear Creek hit a homer with this one. It could be early, but so far, I am impressed."

Took my youngest grandson to the range this morning, and he really liked shooting the short WMR uppers on one of my SBR lowers. This second pistol upper works and shoots as well as the first, so now I am three for three!

well, that's neat, and probably fun but not for me. Too much $ for my tastes.

I have no use for an overweight, overbulky rimfire rifle using overpriced ammo.

If you've got an AR and want another caliber, fine. I got barrel for all my pistol rounds, and some of my rifle rounds for my Contender, I understand the idea of having something able to shoot more than one caliber.

I just can't see any practical use to a .22WMR, for me. I also don't have a real use for the .22WMR in any gun.

Enjoy what you enjoy, I'll so the same, as much as I can.

I do have a .22 WMR cylinder for my Ruger Super Single Six. Haven't fired two boxes of magnums in over 30 years. When I need more than the LR, I go to a centerfire round and download it to match what I want. Cheaper for me than buying non-reloadable .22WMR, always has been.
