I have a Rock River Arms LAR-8 in 308. My brother has one in .243 Winchester and both are very accurate. The 308 can be bought as a complete gun, but the 243 and 7-08 are bought as a LAR-8 lower reciever and the complete upper of the caliber you want. One thing to remember about the RRA LAR-8, is the .243 and 7-08 can not use the FAL mags like the 308 chambering.

My brother's .243 Predator shoots 80gr Speer bullets under .75" all day and puts the 105gr Speer SP under 1" with no load development at all.

I don't drink or Smoke. I spend my money on gunpowder and gasoline.
