The T12 ST is an over-barrel design, developed for .223 through to 300 Winchester Magnum and to accept barrel diameters up to 0.906" (23.0mm).

This design has a sealed expansion chamber which 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.

5,000x round minimum service life (approx. life of a standard rifle barrel). Constructed using only quality corrosion resistant materials, with high resistance to flame degradation, retaining structural integrity.

High corrosion resistance to salt water exposure. Internal geometry harnesses the energy of the gun-shot to keep the moderator tight on the thread shoulder, resulting in high level rifle accuracy and longevity of the product, eliminating the problems with a moderator unwinding leading to baffle strike. Shrink fit assembly and welded construction developed to resist high impact and abrasion.

2x point barrel support for enhanced accuracy.

Reduced muzzle flash.

Improved recoil reduction to mitigate muzzle jump for solid target aquisition.
