Kinda basic,but i,m very happy with it. I purchased a max-flo valve,from B&A,i opened up transfer port to 3/16 and used 1/4 poly tubing as per Bios H. web instructions, purchased remote fill valve and on-off from georgia paintball,airsource adapter from wal-mart.I dont own a chrona. YET but sure sounds alot more powerfull.Lol. I had more problems with the shaping of the grips,unhappy with them,but the carving part turned out just fine. I tried to get a closeup shot,but one thing i,m not ,is a photographer.
