Cortina Precision EC Barrel Tuner .850 Direct Thread or use adapter to fit your barrel "See Below" in RED
Original EC Tuner is 1.250″ diameter straight and is 2″ long. It’s perfect for 1.250″ competition 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. View adapters here.
This tuner can be fitted behind any muzzle device such as suppressor or brake.
