Hello peeps! finally got my sig 522 yesterday and man this thing is sweeeeet!!I have owned the colt/umarex, S&W MP15-22 and GSG 5's and I will rank this on top of the class!, don't get me wrong all the 22's i have mentioned are good too, probably the smith and GSG 5 are tied for 2nd even though the colt is nice I just did not like the look of the Mags, the smith was fine AFTER it came back for repair. I only have two critique, 1st the mags are really tight and i mean tight, I had to use my power tools to smoothen the sides to make it a little looser, 2nd is if you guys do get one watch outwhen you field strip it, the bolt assembly on mine kinda got dissassemble unexpectedly,I mean the spring came off the very tiny e-clips was a challenge to find but after taking a breather and eating some lunch i got my composure together and was able to put it back together hahaha..Anyway tried it today just 200 rounds and i was able to zero my cheapo red dot in just a couple of shots, I just need to get more mags($17/mag) it takes regular blackdog mags, mine came with several rails to attach but i just used the one for my foreward grips..anyhoodle here it is..
