MDT Rear Bag Rider for MDT Buttstocks, M-LOK and Bolt-On

$74.95$124.95 inc. GST

Increase the capabilities of your MDT buttstock.

The Rear Bag Rider offers an end user an additional 5″ to interface with a rear bag, or compliment multiple shooting positions (Note, the Steel version is significantly shorter than the other models). A flat, horizontal surface aids in linear recoil and the rounded profile reduces snagging on bags and gear. Mil-Spec Type III hard-black anodized aluminum (for aluminium versions). A steel M-LOK version is also available. Attaches to M-LOK compatible and legacy buttstocks. The Bolt on version will only fit older MDT stocks that don’t have the M-LOK slot.

NOTE 1: If you prefer to buy Australian Made, we also manufacture the Ultimate Bag Rider to fit MDT M-LOK buttstocks. Available at the following link:
