I'm tinkering with the idea of building a 20ppc Ar15 for varmints and range outings. Hoping to go 20" with 11twist. I've seen 20lbc previously offered on Columbia River barrels as an 18" but they are no longer on their website. Does anyone have any suggestions or will I need to contact a maker directly? I'm open to any of the ppc/gendel/arc variants.
Edit: It seems like the 20ppc won't be a good fit due to short OAL and the potential for feeding issues. I'm looking at a 6.8spc based 20cal option. So feel free to make any suggestions.
