bushmeat Posted March 26, 2013 Share Posted March 26, 2013 Customer service rep at Rock River Arms told me that the blowback action of rimfire conversion units have a propensity for breaking their triggers.Have any of you found it to be true of two-stage triggers only or does it apply to single stage ones as well?

Daniel defense uppers usually. my 3 gun is an old colt 1/9 skinny shot 5 k thru it in .22. cant shoot any more. dont have time. take i the 6" upper with me. use on my work lower with a giessle sgl stage.over seas a lot.plink at pigeons off the embassy roof at nite. with a gemtech sea hunter titanium "can,"clean about ever3oo Rd's. hope this helps. u couldn't run fast enough to give me anything by r/r to bet my life on techs are morons also. ..cheers jjw Edited March 27, 2013 by jjw Link to comment Share on other sites More sharing options...
Lead-Head Posted March 27, 2013 Share Posted March 27, 2013 Can't see how that makes any sense. That trigger should be able to survive any .22 conversion. Link to comment Share on other sites More sharing options...
ac4wordplay Posted March 27, 2013 Share Posted March 27, 2013 I've got almost 10k on a Nordic NC-22 using a Jard adjustable single stage. Zero trouble with the trigger/hammer. Link to comment Share on other sites More sharing options...
Alaskapopo Posted March 27, 2013 Share Posted March 27, 2013 Can't see how that makes any sense. That trigger should be able to survive any .22 conversion. Actually a .22 is hard on the hammers because the bolt hits the hammer at a steep angle. (90 degrees vs much less on a ramped .223 carrier) I have broken a few hammer pins on my .22 Spikes over the years and seen it happen on other .22 ar's. The only triggers I run on .22 ar's are GI style because in generally .22 uppers won't run right with match triggers in my experience. Pat Link to comment Share on other sites More sharing options...
MstngLX50 Posted March 27, 2013 Share Posted March 27, 2013 As a kid after umpteen thousand rounds with a Ciener I had a Bushmaster hammer peened at the notch a ridiculous amount then it broke. Now I have better stuff and they run great, filthy but great. I built up another lower so I didn't have to worry about cleaning the trigger assembly on my match rifle. Only issue I've had recently was having to remove metal from the bottom of the bolts on a Spikes and CMMG. They were low to the point that the AR Gold hammer was binding against them during recoil. Maybe that was the issue with the RRA. Link to comment Share on other sites More sharing options...
Jaxshooter Posted March 27, 2013 Share Posted March 27, 2013 I run my NC-22 upper on a dedicated lower with a modified GI trigger and have had no problem. Link to comment Share on other sites More sharing options...

When I first got it it would only run on Federal plated bullets then later it got better and better and pretty much runs on anything now. Only issue I have is chambering the first round with some ammo it some times needs to have to bolt pushed closed by hand. Pat Pat Link to comment Share on other sites More sharing options...
