i have one of the jm guide guns, and i did put on it a xo sight sistem and a rail.
But today i put on a wild west loop lever to replace the original, one of the wild west "happy" triggers, and the aluminum mag guide.
This rifle was twisting my hand with the original lever, the loopy made a huge difference. The trigger was basically a drop in but it took up the slack from the original, much better feel, smoother, and lighter.
Would recommend those mods to anyone with that type of rifle.
