Nice little sight - Burris FastFire II Reflex Red Dot Sight, 4 MOA Reticle, Black, 300233

Fine little sight; very petite, and the mounting plate that I used to put it on a Ruger .22/45 Mark III fit perfectly. The plate is an additional purchase, but if you're mounting this on anything with a Picatinny rail Burris makes a model that incorporates that mounting system into the base at no extra charge. The only real drawback of this sight is that it doesn't have an automatic "sleep" or "on/off" function based on a motion sensor, so it's easy to leave the switch in the "on" position with the resulting battery drain when you put the gun up, and if you only shoot once in a while that could become a problem.

Aside from that it's a well-made functional red-dot sight, and perfect for applications that demand a small envelope, like a handgun.
Pros: good price, size, features
Cons: no auto-off function
