I paired this with a passively illuminated fiber optic sight and slapped it on my Nexus pro x. Took about five minutes to get it on target. Now I have a aiming solution for blasters that never needs batteries and can give the elevation correction needed for dart ballistics.
Only cons I've found. When the rail is adjusted for lots of elevation it can wobble side to side, there is a spring to remedy this but the spring is not strong enough to overcome the weight of a large scope or optic. Stick to polymer bodied optics or very small red dots for the best possible results.
