Author David Bahde takes a look at Proof Research’s precision AR 7.62mm. Big-time weight has been shaved off this well-built AR-platform rifle thanks to its state-of-the-art steel barrel wrapped with carbon fiber, whose two materials are mated properly so that the carbon dissipates heat at similar rates as the steel and the materials don’t separate. Bahde notes, “The barrel was so impressive that I’ve ordered one for my 6.5 Creedmoor bolt rifle, which is for competition, gets limited deployment and makes the weight savings worth the cost.” Prepare yourself to go sub-MOA and get 10- to 20-round 1,200-yard groups with this 8.7-pound 7.62mm powerhouse!
