Very good product; very satisfied. It is a little embarrassing lugging around a 22LR tactical, because it looks cooler than it really is. Nevertheless, it is a very good entry-level tactical firearm.
The GERG-522 is a tactical-looking rifle, 22LR caliber, faux suppressor, knob-style rear iron sight, 22 1 magazine, ambidextrous. Overall, it's feel is good, lightweight, and the center of gravity is at the breech; I used it to carry around when away from the range.
The magazine fit snugly but proved to be a little problem. The "follower" must be held for each round and to more than that. Also, be sure to let the follower up to set the rounds after each insertion. (I'm used to the Ruger's 22LR pistol which allowed me to hold the follower farther down to add more than one round.) If the rounds get jammed, extraction is difficult. Unlike other firearms, this will not let you overload the magazine, a good thing, because I don't have to count.
After running 400 rounds through within 30 minutes, the faux suppressor was hot but not enough to scald.
The rifle butt had two problems. First, assembly was difficult (I needed help), and second for my long arms and far-sight, it's too short. I would add about 3-5".
I noticed a lot of powder spray on my bench when I reloaded. Still, it could have been cheap rounds. Be sure to wear eye protection.
The rear sight was odd: I've never seen anything like it. It's a knob which has four slots with varying widths. Also, I didn't know where to line up the front sight; in the end I stuck with the narrowest because of my far-sight. Out of the box, the paper pattern was consistently to the left 3" at 25 yards. There's a notched screw on the right of the rear sight for precision adjustment.
