We have two styles available.
Origina EC Tuner is 1.250″ diameter straight and is 2″ long. It’s perfect for 1.250″ barrels.
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
This tuner can be fitted behind any muzzle device such as suppressor or brake.
