Our ever-popular 18" SPR barrel is now available in a 20" version!  We have redesigned our traditional 20" barrel to incorporate it into the SPR family by adding the Ops Inc step to the muzzle.

We start with the same match grade blank as our 18" SPR barrel and is held to the same rigid specifications.

The 20" SPR barrel has a rifle length gas system.  The barrel profile is .900" under the handguard, .750" at the gas block and features the step behind the muzzle to accommodate the Allen Engineering/Ops Inc suppressor.  The muzzle is threaded 1/2 x 28 to accept a flash hider or muzzle brake.

The .223/5.56 Wylde chamber gives excellent performance and reliability with a wide variety of ammo. The barrels also feature M4 feed ramps for reliable feeding.
