    Any info on RRA 22LR uppers?

    Bear Creek Arsenal just came to market with a 16" side-charging 22LR dedicated upper. It looks to use the same bolt as the RRA, JP, Nordic design except they put a side-charger on it. $350 if they're still in stock...

    Any info on RRA 22LR uppers?

    https://www.rimfirecentral.com/forums/showthread.php?t=1214793 This fella has posted a couple times about his RRA 22LR. I have a couple different brands of 22LR uppers already but I wouldn't hesitate to go this route. It is my understanding that RRA, Nordic Components, and JP Enterprises all...

    CMMG AR-15 .22 L.R. Conversion Kit

    Firing .22LR from your AR using the CMMG conversion bolt is a hoot. I suspect you'll enjoy it so much you'll want to build a dedicated upper for it. A dedicated barrel (and collar) will give you better accuracy. 22LR is pretty dirty so copious amounts of oil will only gum up the works...

    Does anybody know where to find a .675 collar for dedicated .22 AR upper?

    Yes. This issue was exposed a while back when a few of us at RFC ordered 17HM2 barrels. At least that's when we discovered it anyway. I think Lothar Walther had pre-made a bunch of 22LR barrels with that dimension and put a disclaimer on their website that you needed the "older" collar. Some...

    Savage Axis Recoil Lug

    10-4 Thanks...he works out of town so I'm waiting to hear if it is actually in the old stock. Thanks for the response.

    Savage Axis Recoil Lug

    My buddy bought one of those inexpensive package deals that came with a scope and injection-molded stock. The intent is to eventually barrel it and put it in a chassis. It's chambered in .308 Win and he's already put it in an Oryx chassis. I took it apart this weekend to clean it and just...

    WTB FOUND

    A fella over at RFC.com only had to wait a month for his RRA 22LR NM A4 Upper Half. He ordered on 3/24 and said his CC got dinged yesterday.

    WTB FOUND

    The Rock River Arms 22LRs use the same bolt and barrel breech as JP and NC. Long lead but still available.

    Appleseed Question

    What sight is that? Does yours have the 10mm dovetail with the crowned top? I'd like to do something similar to my Zastava MP22.

    Need help putting together 22LR AR15

    I imagine the Volquartsen version would be on par with Beyer. I'm not sure why all these custom 10/22 barrel makers (Whistlepig, Kidd, et. Al.) are not making AR22 barrels. Hell, the machining has got to be easier and the AR barrel nut system is far superior than the 10/22 method. A CMMG...

    Need help putting together 22LR AR15

    ...how can you stand it? I'd love to hear how it does for you. This comes up occasionally; as one who's been in this rabbit hole for awhile now I can offer some insight from my own experience and my own research. I don't have a JP/Nordic/Rock River Arms (all of which use the same bolt) but...

    Precision AR .22LR Upper?

    The CMMG bolt is the most supported out there right now. My 18" Lothar Walther barrel shoots great. I've had several 1.5" (10 shot) groups at 100yds with it with a couple different ammos. Once nice thing about the CMMG setup is that you can add the redi-mag adapter or the catch22...

    Precision AR .22LR Upper?

    I ordered mine on April 10 of this year. I think it was 3-wks to receive it. Just looking at their Instagram, I think he got real busy with Vudoo and RimX barreled actions right about that time. I would have been really disappointed it he had told me they weren't doing AR22s anymore. I'd have...

    AR-15 Rimfire conversion for NRL22?

    The one on the right is the TS bolt. You're right! The bolt face is nearly identical but I placed the CMMG bolt up to the TS barrel and the ejector is oh so slightly clocked a little higher. You can see in the pic that the left that the ejector on the CMMG bolt, call it 9 o'clock; the ejector...

    AR-15 Rimfire conversion for NRL22?

    ob - I've thought this barrel could could be a good blank to start with: https://www.gunpartscorp.com/products/884540 I'm not sure which chamber will best suit your needs. At the risk of stating the obvious, I think the Bentz chamber is considered a "match" chamber for semi-auto rifles. Maybe...

    AR-15 Rimfire conversion for NRL22?

    Are you wanting to re-barrel your Tactical Solutions AR-22? They are out of the AR22 game so I'm not sure how you're going to do that. Someone would have to reverse-engineer their barrel breech/collar setup. Their bolt is awesome and I love that they don't use the collar but I'm afraid a...

    Iron sights on ruger rpr 22 need advice

    I went down this path with one of my AR22s. Ended up with a Lipski barrel band style front base, a Lipski flat top rear sight base and Lyman MJT sights. I wanted "Match-style" sights without the "match price". This setup works great. I have optics on several other AR22s but wanted one with...

    Precision AR .22LR Upper?

    Well, I know this thread is pretty old but since I commented on my Lothar-Walther barreled 22LR, I did purchase a Keystone Accuracy Upper. Both are 18" heavy contour. The Lothar Walther is a constant taper down to about .740 at the muzzle and the K.A. is more of an HBAR profile with .750 at...

    Rimfire SOLD Tactical Solutions AR-SBX 22LR

    I see you have a couple TS Uppers for sale. You wouldn't happen to have a TS bolt only for sale would you. I happened across a TS lightweight barrel a while back but no bolt. TS will not sell me a bolt by itself. I have another complete upper so I'm not dead in the water but it would be nice...
