I managed to dismantle my S&W m3000 shotgun (known as the walmart shotgun). I kinda sliced it into two parts after unscrewing tons of ?screws? (i dont know what is vis in english), and all the internals fell on the floor. Its not a big concern cause its a 40-50-60$ gun but it will still be long to put evrything together. I putted the spring out and mesured its lenght (16 cm). 15-25 fps wont be enoff for me cause it only shoots 250 fps right now, and has a 75 foot total range.:x:. I want to use it outdoor this summer.

Ouch, trying to get close to 400fps out of a Walmart shotgun? No chance in hell, unless you want to get your kills by having your spring & piston fly out through the barrel and get your hits that way. Not sure of any springs you could buy that are aisoft springs and will fit your shot gun. Need to measure the inner diameter of the spring also, sniper rifle springs ar elong and have a small inner diameter (7mm or 9mm) and AEG springs tend to be around 11mm ID, but can range from 6 1/4" to 7" long (even among the same brand and rating, PDI are the worst!)
