Barrel Tuner

Tapered EC Tuner:  Tuner tapers from 1″ to 1.250″ and is more suitable for smaller barrels such as those used in F-T/R and PRS/NRL rifles.  Minimum muzzle diameter is 0.850″ due to threads being .850-24″

This tuner can also be used in rimfire or competition rifles by using our thread adapters that come in 1/2-28, 5/8-24, 3/4-24, and M18x1.  View adapters here:

This tuner can be fitted behind any muzzle device such as suppressor or brake.
