Things I liked:Well made, light weight rings. Height is med/high. A 44mm objective scope (Hawke SF) fit my Air Arms 510 w/room to spare. What others should know:Remember to not max out your scope's adjustment when sighting in a zero at long range. Use shim(s) on the rear scope ring bottom. Your point of impact may wander otherwise.
Things I liked:Surprisingly good gun. Actually has accuracy and even better range than a $350 AEG I just bought.
Things I would have changed:Stock is a little long for my shorter arms. What others should know:Very effective hop-up.
A bit heavy, but this is a replica of the all-steel Thompson.
Pyramyd-Please stock parts that wear, so I don't have to have this gun down for long.
