Excellent sight for budget price - Holosun Elite 2 MOA Compact Green LED Dot Sight

Superior build quality, exceeding that of the Vortex SPARC and Strikefire II by a large margin. On par - or very near to - the build quality of Aimpoint T1. The green dot is VERY easy to pick up and I like it a lot more than red. Very bright; at low settings the dot is very well defined (even given my astigmatism) though for me it "starbursts" at medium to high settings. It is still usable and accurate enough, though. The "shake awake" feature is very convenient (however, a shake isn't necessary - just picking up the weapon will activate the sight.) It's perfect for a PCC or small carbine; mine's mounted to a Beretta CX4 Storm.
