Compact Bag Rider for Magpul MOE or CTR stock

Follow TinyHatchetBuilder to never miss a new preparedness model!

This “Compact” Bag Rider is designed to fit the Magpul MOE or CTR stock and provides a footprint for stability when used with a bag. It enables the user to still have use of the stock bottom strap slot if required. 

Requires three M4x20 screws and M4 nuts for installation. I recommend putting some Loctite blue on the nut to keep the screw from unthreading during use. Sized for either a socket head or button head screw to fit. I tried to optimize around a single common screw that comes with most M- screw sets to minimize complexity and make removal easier if the bag rider will not always be used.

The print profile will work on printer beds A1 mini sized and up!

I’ve had good success with using 8 walls, 6 top shell layers, 6 bottom shell layers, 25% sparse infill with a Honeycomb pattern, 50% Infill/Wall Overlap and supports enabled. These are the settings in the print profile and what I would recommend if printing from a download. I have used both PLA+ and PETG. If your stock stays in a safe then PLA+ will be fine, if you are ever using it then PETG or better would be my recommendation to account for impact/vibration/temperature.

I have a whole suite of accessories for the Magpul MOE/CTR as well as the B5 Sopmod and the B5 Bravo.
