I bought 2 super sniper scopes fixed 20x I think they are very good for the money I use mine for F class target shooting one on my Remmie 40 X 308 and the other on my BSA CFT 6.5 x 55 ive not used them at low light but with a 30 mm tube they shouldnt be that bad, mill dot reticule and unique rear paralax adjuster in the same place were the zoom is on adjustable mag scopes so its easier to focus from the normal shooting position. All in all avery good scope for the money.
