Would this fit on ar10 jd machine lower Expert Answer

The Strike Industries AR Modular Magazine Release should fit your AR10 lower. Generally, the AR10 platform, both DPMS and Armalite, will accept AR15 mag release buttons and mag release springs. So you should not have an issue fitting this mag release to your lower.

I installed it and thought WTH the buttons are ok. But if you push forward and in like most fingers do slightly it catches and jams up. You have to be dead on to drop a mag. I ended up ordering a plain mag release.
