I’m rating this at three due to the usability of this kit. I don’t use airsoft I use 4.5 this kit is designed for 6.0 I’m having to order this by necessity because The O-ring the CO2 sealer and the actuating seal assembly are the only things I can use in this kit because everything else is geared for 6.0 mm wish this company would start carrying 4.5 BB type which is the .177 caliber there is none available anywhere in the United States that I can find I guarantee they would sell this is for a Springfield armory 1911 BB pistol

I would give this bag a five and it’s not the mag’s problem. Problem is it’s 6.0 mm. I’m having to buy this because I can’t find the 4.5 or the .177 caliber steel BD overhaul kits they’re the exact same mag, exact same seal. The only thing that’s different is the follower, the spring and the mag of the BB tower Other than that this is a solid 5
