Hows it going everyone. Im new here and relatively new to airsoft. A few years back I purchased a mystery box, in which I got an APEX 811 RIS. I never got a chance to actually use it tho, but not im looking into actually start playing. I cant seem to find much information on the gun at this point and it seems like APEX isnt even a thing anymore, I do believe they were made by Classic Army tho. My question is, does anyone have any idea as far as upgrades for it and such, and if it even needs any? And what would fit in it and what wouldnt, I just dont even know where to start really. Thank you for the help.
