Control Bridge for MDT Chassis

MBR Rimfire Accessories Collection

This series is a set of custom 3D-printed rimfire accessories I designed for use with my Bergara B14R. The goal was to create practical, functional kit that also looks clean and cohesive, with matching hex pattern detailing and my MBR logo throughout.

Current designs include:

• AICS Magazine Holder – Tek-Lok compatible, adjustable fit using a resizing insert. 
• Chamber Flag – Clear chamber indicator, featuring the same hex styling and a lanyard loop for easy handling and visibility.
• Control Bridge for MDT Chassis – designed to fit ACC Elite, ACC Premier GEN2, and LSS Gen 3 Competition forends.

All models are designed with real-world use in mind — easy to print, sturdy, and with just enough style to make your gear stand out.

More designs to come in the future.

Control Bridge for MDT Chassis

UPDATE - 15/03/26 - Added a second plate to each profile with a 2" longer version of the bridge.

This is a custom control bridge designed to fit:

• MDT ACC Elite Chassis System Forend
• MDT ACC Premier GEN2 Chassis System Forend
• MDT LSS Gen 3 Competition Forend

This slimline bridge runs 9.35" and covers all of the screwholes on the LSS Gen 3 chassis, providing a solid, consistent surface while still keeping things lightweight thanks to the hex pattern cutouts. It improves bag handling, stability, cuts out mirage and adds a clean aesthetic touch with the MBR logo worked into the design. It is attached to the rifle using 6x #6-32 x 3/8" button head screws.
