Looking to upgrade the trigger in my son's AR. I started with a complete Spikes lower and Nordic .22 upper. For those who haven't used the Nordic or want a .22 upper, these things are pretty sweet. Very reliable and pleased with the accuracy. He will be getting a .223 upper for Christmas. I would like to upgrade the trigger. I have read with the .22 lr triggers can be problematic. Anyone running a .22 have any suggestions for a better trigger? I am not looking for bench grade pull weight, just something with less creep, better reset, etc. Thanks for any info.
