Masterpiece Arms Magwell Plate Kit for BA Comp, ESR, Matrix, Matrix Pro and Hybrid


This magwell plate system is for the BA Comp, ESR, Hybrid and Matrix short action chassis. These plates are designed to protect the magazine and provide the benefit of giving the shooter additional stability when shooting positional stages by digging into the positional bag.

Machined from Solid 6061 aluminum, black anodized, ready to install.

These magwell plates are designed only for the BA Comp, ESR, Hybrid and Matrix Chassis short action chassis. (Not the Matrix Pro or Hybrid CZ).

These plates may require the purchase of the Magwell Plate System Upgrade to be used on your existing chassis.

If your chassis does not have the 4 drilled and tapped holes around the front action screw hole, you will need to update your chassis.

If your chassis does currently have the 4 hole pattern, these are ready to be installed with no modifications.
