Hey all, I just bought a Saiga .223 with the 20.5" barrel. I have been searching tons of sites for stocks, grips, etc... I kept coming across this site and found a lot of good info. Thanks. I am looking to keep the trigger in the same place. I am looking for a 6 position AR style stock w/ pistol grip, tri-rail system for the front, virtical grip, to get my gun the way I want it. So, where have you found the best place for Saiga accessories? Thanks.
