Increase your replica's ergonomics and comfort with a BCI Angled Inset Thumb Rest 2.0 for your M-LOK rail. The gentle angle and robust design provide strong and comfortable thumb placement support on either side. Optimize your shooting experience with this expertly crafted accessory.

The 2.0 version is now ready to meet your torque specs up to 15 inch pounds. We have updated the M-LOK hardware to 10-24 for a better bite and a more robust 4140 T-Nut.
