This HWS is a great buy due to its great versatility and ruggedness. I have it on a CMMG AR-15 and was able to fit this optic, an Eotech 3x magnifier, and Magpul flip-up sight all on the upper reciever leaving my handguard rail free for other uses. The glass is crisp and clear allowing for fast target aquisition at close range.
The only issue is apply this HWS at targets at 300 yards or further. I have to set the reticle at the lowest setting to get a red dot clear enough to engage the target. I have shot with Aimpoint red dots before and they seem to be a bit clearer. Overall, Eotech is a great brand to trust in because of their quailty products and that's why the military uses them as well.
Pros: Light, quailty build, compact size
Cons: Biohazard reticle can be a bit blurry due to certain light conditions while shooting at distant ranges
