I'm back with another project, and this time I'm looking to build a semi auto precision rifle, sticking to the lines of a DMR (Designated Marksman Rifle). Before anyone asks, I'm very attached to my 308 Win caliber so yes I'm looking for something in 7.62 NATO/308 Win. I'm NOT looking to build from scratch but off of a platform. So far I've felt around with pricing and performance with the FN Scar 17s, the Springfield M1A either full size or the 20" SOCOM II, and an assortment of AR10s. The final obstacle for this is that....well, I live in CA. Needless to say, it has to be CA legal. Any suggestions?
