JMS Arms T12 .308 Scout Sound Moderator 5/8 UNF Stainless

The T12 ST is an over-barrel model, designed for 6mm through to 300 Winchester Magnum and to accept barrel diameters up to 0.906″ (23.0mm). This design has a sealed expansion chamber that comes back over the barrel allowing for better weight distribution with dual barrel contact points resulting in optimum accuracy due to controlled barrel harmonics during firing. The threaded muzzle of the barrel winds into a barrel support spider located behind the groove seen on the outer tube. This aligns the muzzle to the bore of the moderator. Located at the rear of the moderator is a synthetic bush which creates a secondary support on the exterior of the rifle barrel.
