Review on Versatile Red Green Dot Rifle Scope With Reflex Holographic Optics For Airsoft Guns – Fits 11Mm/ 20Mm Rail With Lens Cover (No Battery Required) by Chris Wagner

This product is absolutely garbage. It don't even work on the air pistol. The pistol no kick or nothing and the sight go crazy. I zero in the sight and I went out for a shoot and I wasn't hitting the target, first I blame on the gun then i realize it was the sight problem the pellet were going everywhere not even on the target . I was shooting a crosman 2240 they have history of being an inexperienced accurate pistol . The target was at 25 yard! This sight is useless don't recomend.
