MPA EC Barrel Tuner




Add the EC Tuner, a product by Erik Cortina, to any bolt action rifle build by MPA using a 416 Stainless Barrel (This cannot be added to carbon fiber barrels).

This tuner design adjusts the harmonics of the barrel, providing the additional method of fine tuning your handloads, or improving accuracy performance on Factory loads.

This can be added to any rifle build completed by, or being currently built by,  MPA. Please contact customer service to add this to an existing build, or purchase the add on through the website when placing a new rifle order

There are 2 options on these EC Tuners. A square tuner or a tapered tuner. See images for differences. The price is the same and DOES NOT includes Installation.
