"Completely love it!!!!
I have never bought an extra mag before since I do not have a need for one while playing 2v2 in my timber but when I upgraded to a full metal riffle I thought it would only be right if I replaced the basic plastic mag with a metal one. I cannot express how happy I am that I chose to do so. It feels much better than the plastic and is much sturdier. The tan magazine looks great with my tan rail covers and matte black gun!

"Awesome, fits and feeds perfectly to my gun while some other mags don’t

"Only cons are cosmetic - blue or green color is ugly and paint scratches easily. Other than that it is a perfectly fine low priced hi cap.
