Seems a lot simpler to just go with an LR-308 or AR-10. Both work fine with 308 cartridge length and pressure. It will even handle the 300 Saum 300 WSIM sized cartriges.
For one thing the AR-15 bolt and carrier are too short to cycle a 308 besides being too weak. What's left of an AR-15 modified to 308 which differs from the LR-308? Lots of LR-308 parts interchange with AR-15's. (stocks, grips, triggers,l etc. With decent bc bullets the 338/7BR is a 2.8" (308) length cartridge. With a decent BC bullet the 458 Socom is a 458 Win Mag length cartridge! It jsut wastes their performace capability to use them in short actions.
