MasterPiece Arms ( MPA ) Mag Block Insert
$14.00 Add to cartMag Block Insert
This insert is designed to fit into the mag catch slot in Short Action MPA BA, BA Comp & Hybrid Chassis. This part was originally designed to work with Curtis Custom Vector Actions, for customers who wanted to run AICS magazines (on an AW Cut Action), to eliminate the gap before the AICS mags make contact with the action. However, we have also found these very useful for eliminating feeding issues when a competition shooter is putting weight or pressure on either the bottom or front of their magazine, such as when shooting from a barricade.
When installing these, after you have verified fit and tested with a magazine, we recommend that you remove the insert and place some adhesive to the top flat surface to make contact with the top of the pocket in the mag slot in the chassis. Superglue or similar is recommended.
Slight polishing may be required for proper fit. You will receive (1) Version 1 and (1) Version 2 inserts with each order. Please watch the video below for installation instructions.

MasterPiece Arms ( MPA ) Enhanced Bag Rider
$129.99 Add to cartProduct DetailsOur newest Enhanced Bag Rider design was designed for F-Class Shooters, and provides a rock solid rear support when using an appropriate dual ear (or âVâ) rear bag, such as the Protektor Series Rabbit Ear Design. It also provides an enhanced level of rear support for all long distance shooters, whether youâre a belly shooter or top level PRS competitor. This design has been successfully used this year at multiple PRS events by Team MPA Shooters.
The stability this rear bag rider provides is incredible, especially when shooting groups. If youâve ever had some challenges keeping the rifle ultra stable when prone, this accessory will improve performance.
This Enhanced Bag Rider works with all BA, BA Comp and BA lite chassis that have a 3 hole pattern on the bottom of the buttstock.
It comes with a black cerakoted bag rider, 2 set screws, and a turned step shaft designed to be inserted into the monopod slot for installation purposes. The side profile is notched to all use of the bottom flush cup for sling or bag attachment.
