hopper clip if you use alot of paint and are a front line player.
The AT-85 is extremely accuarte which is it's best asset. the sight is great it is like a real gun. It's loud which is good and bad. Clip feed makes sure you never break a ball. Looks great, reloads fast, it's semi ROF is equal to that of a stock cocker, extremely light, if you keep it maintained properly you will love this badboy.
The clip is easy to mess up but is easy to fix. You will bend pins and maybe nock off the chain and you will have to fix sometimes and it is kind of long even with a 47 ci tank.
Great gun, performance like a cocker, orignality, shoots great out of the box. Don't listen to the people who say it breaks alot if it breaks its cause of you not knowing what you are doing not the gun. Don't run Co2. Keep it well maintained and enjoy!
