Did a search and surprisingly did not find much relavent data. Looking to replace my stock that came with my parts kit with a better model. Don't know really where to start looking. Need significant adjustability since the wife will be using this gun also. Standard AR MilSpec lower. If it had some kind of recoil pad for her that would be nice and definitely need a place to attach a sling. If this has been discussed to death before and I missed it in my search just put up the link and accept my apologies. Thank you Wanna kill these ads? We can help!
