The sight is desriable in every respect save the battery cover problem. About half the time the cover alone pops off, the other half the cover and battery eject together, and can usually be found within 2 ft. of the shooter. Used on an AR-15 clone in .223 Rem.
Pros: easy target visibility, adjustment, mounting
Cons: battery cover pops off about every 5-7 shots
