Worth a Try

by CA, Verified Owner from VA, United States Written on April 7, 2026
I ordered this for one of my guns with a larger MLok handguard. Works great with the hand stop I have and creates a more secure hold on a gun I can’t wrap my thumb around the top of.

MDT M-LOK Adjustable Thumb Rest

by silverbullet, Verified Owner from CA, United States Written on October 4, 2025
I recently added the MDT M-LOK Adjustable Thumb Rest to my MDT LSS GEN3 chassis, and it's been a solid upgrade. Fitment is perfect — it mounts directly to the M-LOK slots without any hassle and feels like it was designed specifically for the GEN3 chassis.

In terms of functionality, the thumb rest offers excellent ergonomics and a much more stable grip. The adjustability is a big plus — you can dial in the exact position that feels right for your hand and shooting style, whether you're bench shooting or out in the field. It definitely improves control and comfort during longer sessions.

If you're running an MDT LSS GEN3 chassis and want to enhance your grip and shooting stability, this thumb rest is worth every penny. Simple to install, highly functional, and built with the quality you expect from MDT.

Highly recommended.

does what i was looking for

by Paul Munsch, Verified Owner from PA, United States Written on July 8, 2024
Everyone’s AR setup is unique to them. That being said this may not work for you or maybe it will. based on how you hold your barrel and your hand placement. For me this works really well right next to my white light button. I can keep my thumb out of my optic line, keep great securement of my firearm. Then with a small movement it’s up to my light
