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 is the original EC Tuner and will require a qualify gunsmith install. The barrel will need to be contour and thread for this tuner.

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

The price for the square tuner DOES NOT include Installation.
