My lower is a RockRiver,, top is a complete CMMG, it groups about 1.25moa with CCI standard velocity. Of course groups shrink as the quality/price of ammunition used increases, it'll group under 1moa with Tenex but I haven't won the lottery yet so I'm still shooting CCI sv!
Most of the targets at NLR22 are bigger than my group sizes so it's good enough.
I use the S&W magazine with a redi-mag adapter, it works flawlessly.

 

Been thinking about adding another plinker

 

It took RRA a year to get that upper built for me. The holdup, from what I was told, was that Wilson had not sent them the barrel.

Anyway, I feel like it was worth the wait.

 

I consider my gun a legitimate NRL22 rifle and there's a bunch of 22's that are either not accurate enough or lack the stock configuration to use the necessary accessories.
This picture is from when I first started shooting NRL22, per normal once you get into anything you find out what works for you and what doesn't, I've changed the scope, bi-pod and ammunition. Added 5 magazines to give me more time to set up the scope during the match.

 

When I click on this photo, I get redirected to an unfamiliar website for a photo hosting service. I see pretty girls and diet pills advertising. I like girls, but; that is often a warning. RFC will host all our photos for free. No need for this. Not really blaming Kevin here. But this is his post.

To clarify, the problem with links is they may seem like a legit web link and may not be. It could be legit photo_bucket or some site spoofing photo_bucket. Or photo_bucket has advertising from a questionable web site. You dont have to click on an ad. Just hover the mouse can activate spyware. No click needed.

There is probably nothing I can do as a humble member, but; I dont like links hidden under photos like this.

 

Do you have any follow up reports on that RRA regarding reliability and accuracy/precision? I've been waiting on a complete CMP NM A4 rimfire for about 14 months now that should be done any time. Somehow my order got lost and so they created a new one a month ago and said about 4 weeks to finish. I'm on the verge of cancelling the order.

 

I use the Black Dog 15 round that mimic the size of a 20 round 5.56 mag without issues.

 

Does the RRA have last round bolt hold
open?

The bolt on RRA is held open by the follower on an empty mag. I don’t think you can manually lock the bolt back with standard AR-15 bolt catch. A Catch 22 would probably lock the bolt back but might not be actuated by the magazine follower.

I ordered the AR Catch-22. It will not hold the bolt back on my RRA upper.

 

I have only seen pictures of the RRA dedicated 22 LR upper and bolts. The bolts look like the early pattern Nordic bolt. I’m unsure which bolt RRA is currently using. I don’t own a Catch 22. If your Catch 22 will not work with your RRA send me a PM and I will buy your Catch 22. I have three dedicated 22 LR uppers where I can use a Catch 22.

Here is what I’ve read on Catch 22 web site. Uppers or bolts compatible with Catch 22 version 1


Nordic Components V3 upper receivers (rounded bolt)


Catch 22 is not compatible with these uppers (bolts)



Nordic Components V1 upper receivers (square bolt) early version
