PROOF Research PR-10 Barrel (Caliber Matched Gas System)

 

PROOF Research carbon fiber-wrapped barrels are up to 30% lighter and 300% stiffer than stainless steel AR barrels of equivalent dimensions. PROOF’s mastery of combining advanced composite materials with their unique manufacturing process has opened up new possibilities in the world of high performance AR barrels. PROOF Research’s carbon fiber-wrapped barrels provide an alternative to traditional AR barrels while still possessing match-grade accuracy and improved heat dissipation while at the same time exhibiting no point-of-impact shift during high-volume of fire.

With the PR-10 Carbon Fiber Barrel, PROOF Research has taken the standard rifle length gas system normally found on LR308/AR10 barrels and extended it by 2 inches. What this does is allow the higher pressure calibers, such as the 6mm Creedmoor, 6.5mm Creedmoor, and .260 Remington to run and function more reliably by extending the dwell time and slowing the carrier velocity.

**All PR-10 Barrels will ship with the appropriate length gas tube**
