if i was buying the met-pro looks pretty damn good to me.
i got a primary arms and i like it pretty well--so far no issues --but it only had RED optics--no green--
i do like the ACOG series --i liked them better when uncle sam was paying for them though.
i have a couple 30mm hammers and their very good for a $29 sight systems. only thing is they eat these 2032 batteries up pretty quick. and i am so bad to forget and leave them on--LOL--
so far all have held zero and shoot accurately.
to me though it is difficult to beat a conventional scope.
since my eyes ain't what they once were a nice adjustable scope with good glass , and conserve that precious ammo--cause if the big "O" has his way--ammo is going to get to expensive and scarce for all these 0-powere blaster optics--
