Good product for the money - Barska 4x20 Electro Sight Rifle Scope for M-16 Carry Handle Mount

Buyer must understand that this is not a top-of-the-line product. It is designed for use on old style M16 carry handles, and that it does well. As a previous reviewer said, the mount is probably the best part of the design, as it is solid and holds its zero. The optics are not excellent (hey, price is $70, remember?), but appropriate for occasional shooting in daylight. Zero it at 75-100 yds. and leave it there. It should be good for any target in the 50-200 yds. range. It is not a variable power rifle scope, so I can't understand the comment by said previous reviewer. I recently used it in a practical shooting competition, having previously zeroed it for the longest distances of the match. Made me look a better shooter than guys with the $500 scopes.
