A good company to do business with, Royal Mail eventually delivered it a day late which has nothing to with Xtreme Tactical, I will buy in the future.

Replaced a Bushnell Holo Sight I'd had for decades but that had stopped working. Both sights have a "circle-dot" reticle - perfect for my shooting needs. The Holosun seems well made and robust. The quick detach mount is a welcome bonus. HOWEVER I haven't yet had a chance to shoot with it so can't say how easy it will be to sight in and actually use in comps. But so far I feel positive about the sight plus the buying experience from Extreme Tactical.
