Kevin Holman Posted January 1, 2017 Share Posted January 1, 2017 I am bumping a REALLY old thread hoping to get some more info from Kurtm. :-) My nordic bolt and barrel are below, from a complete factory Nordic rifle. Now, you stated anything with a square bolt is GEN1, as mine is, but I see differences between mine and Jesse's. My "nub" on top for the charging handle is machined off smaller, my bolt appears to be lightened more, and my ejector is definitely part of the upper receiver, bolted in. I also notice my hammer nug that cocks it back is not ramped like Jesse's, but 90 degrees. So I am curious is this a newer "Gen 1" or older than Jesse's... I was considering ramping my bolt just a little bit, since I can detect some wear here. Any advice for or against? I am using a RRA 2-stage in this setup and every runs 100% flawlessly. Another question - what are the extra cutout's on the barrel extension for? These are unused. Were these for the barrel extension mounted ejector that mine doesn't have? And lastly - is there any way to get an Ambi charging handle on these Gen1's, or run a standard CH? Does the new Gen 3 RB model use a standard CH?

kurtm Posted January 5, 2017 Author Share Posted January 5, 2017 I don't know what Jesse has, I do know he got his a while back and if what you describe, it is an earlier gen 1. Yours is a very late gen one. The barrel is for a gen 2/3 and was being used on the very last of the gen 1 uppers in hopes the newer model gen 2 would be in production soon. The cut outs are for the barrel mounted ejector which is the way gen 2/3 guns are. There is no way I know of to run a different charging handle in a gen 1 receiver. Right now I am a very long way away from my .22 uppers and for the life of me can't remember what charging handle the gen 2/3 take. Sorry. Link to comment Share on other sites More sharing options...

Fastsc92 Posted April 7, 2017 Share Posted April 7, 2017 Hey guys, New to this site and saw this thread regarding the Nordic Components 22RB upper and bolt discussion. I had a quick question regarding this product, as I'm interested in purchasing this within the next few days.... I see that it comes with a BlackDog brand magazine. Is it possible to use S&W magazines? More importantly, can I use the Better Mag adapter with this upper/bolt so that the bolt will stay open on the last round (vs. being held with the mag follower)? I really like the idea of being able to drop the bolt using the standard bolt catch/release and chambering a round from the magazine. This would more closely mimic my other .223 platforms. I would imagine that if it's only held open using the mag follower, that you'd have to rack the charging handle in order to chamber a round, which would be very annoying especially reloading during rimfire matches/shooting events. Any info would be GREATLY appreciated. Link to comment Share on other sites More sharing options...

Any info would be GREATLY appreciated. Regarding better mag adapter.... 2 part answer By default, the adapter wont work with nordic gen 3. There is just a bit too much material, You can dremel to remove some materials from the adapter on the extractor side and the back/bolt release side so that the bolt can cycle correctly... this works great to take out the slop/loose s&w 15-22 mag issue. On the bolt hold open... The standard ar15 bolt release will not work on gen 3 bolt, the std ar15 bolt release will catch the back portion underside of the bolt preventing the bolt from closing. In a sense it worked as a bolt hold open BUT.... when used with the better mag bit that raise with the mag follower and raise the ar15 bolt release also... the bolt release catch as the bolt strip the last round from the mag.... so the last round is partially chamber and then the bolt would stuck not close all the way..... Is the gen 3 bolt firing pin pinned to prevent damage to the breech face? If used without the bolt hold open. I worry that if i dry fire after the last round it would eventually damage the breech face Edited July 26, 2017 by bitslizer Link to comment Share on other sites More sharing options...

I have not yet have chance to seriously shoot this upper yet. Only was able to shoot standing unsupported at 25 yards and I'm a new/lousy shooter I've came across a 22lr specific bolt catch that appears to work with the nordic gen 3 bolt. at least when I used snapcap and pull the charging handle they seem to work right and correctly hold open the bolt by blocking the bolt feed/round stripper . https://www.arcatch22.com/ So I'm going to build a dedicated lower instead. Hopefully I will get to goto the outdoor 100 yard range bench shooting over the next few week (if wife/baby allow) and see how it compare to my S&W 15-22 and my budget build AR15. I mostly build this nordic because I was thinking to do the appleseed training and the 15-22 ban doesn't appear to be lifting ever. For those wanting to use the S&W 15-22 magazine the AR catch22 bolt hold open will not work with the bettermag adapter by default. 2 options here.... 1) Don't use the better mag adapter and use AR catch 22 with the derlin shims on the 15-22 magazine. Which works but then the mag cannot be share with the 15-22 until you take the shim off. 2) Remove more material toward the back of the better mag adapter so that it doesn't block the arcatch22, note that this will PERMENANTLY render the adapter no longer be able to perform the bolt hold open function for ceiner/cmmg style bolt. So the better mag adapter in this case merely function as a shim installed in the lower for a better fit for the 15-22 magazine only and does not have any bolt hold open feature, the BHO is accomplish via the ARcatch22 bolt release. in both case would mean a dedicated lower (unless you consider swapping the bolt catch quick/easy field option, potentially of losing spring/plunger made this not an option for me) I'm going with the 2nd route as I like the idea my 15-22 mags being able to share with the Nordic without the shim. I'll see if I can post an update once I get this all finish... need to goto harbor freight to buy a rotary tool to mod the adapter (last time I borrow my friend's dremel) Makes me want to get a 3d printer and see if I can print a mag adapter....

bitslizer Posted August 13, 2017 Share Posted August 13, 2017 So finally got this Nordic 22RB uppers working right with Bolt Hold Open on S&W 15-22 Mags, as above post, end up with a dedicated Lower and a ARcatch22 bolt catch and a bastardized Better Mag adapter to function as a shim (so I don't have to shim the mag and they can be interchangeable with the 15-22). Videos of it working, don't mind the missing FCG, the trigger is being RMA warranty. Grip is just a cheap place holder till I finish swapping things around.

Still have not bench it yet, but i just shot riflrman 2wice on my first appleseed. Best group was a 5 rounds 2 moa group prone unsupported I also found out the nordic bcg does not like my ruger elite 452 trigger as it has a notched hammer causing bind and light primer strike, have a geiselle 2 stage on the way Link to comment Share on other sites More sharing options...

Finally had a chance to go to the outdoor range. Attached were the 3 best 5 rounds groups I shot. Please note that I'm very new to shooting as I just started Jan 2017 so still working on my skills and techniques, appleseed did help even when bench shooting.... so this Nordic 22RB upper can shoot 1 moa or better. I shot 4 different ammo today.... CCI AR tactical, CCI standard velocity, Aguila super extra subsonic/std velocity, and RWS target (orange and black box). Surprisingly my Nordic upper prefer the cheap CCI Std Velocity as it consistent shot the best, the aguila and RWS kind of alternate, the AR tactical shot the worse but as this was supersonic round I wasn't surprise. All the ammo cycled fine, no duds, no fte/ftf, no light primer strike. (I was having light primer strike issue with the Ruger Elite 452 2 stages trigger with notched hammer, swap to a geiselle 2 stage) Interesting thing was I zeroed using the CCI AR tactical (as I have crap load and they were cheaper compare to the other 3), but did not zero between ammos,the POI varies with the different ammo, I was expecting the POI to shift up and down due to velocity difference creating difference in drop. but the RWS tend to shoot to the left while the aguila shoot to the right, is that typical...?

Wormydog1724 Posted February 10, 2020 Share Posted February 10, 2020 I have a Gen 1 NC22 upper from the BS group buy. I know it has around 10k rounds through it and it has been very reliable and plenty accurate for my 3 gun type training. This year I am dedicating myself to more rimfire training and I have 10k more rounds ready to go. I'm running a geissele S3G trigger and it's been fine. Every now and then I'll have a malf with bulk pack federal but that just gives me a great opportunity to transition to pistol or work on my malf drills. I've ran mine suppressed and unsuppressed and as long as I'm using federal bulk pack, it just goes and goes. Good stuff Nordic, and kudos for continuing to improve the design.
