with 0.12 gram bb's it goes 550fps and 0.20gram bb's 470fps
Yes, every airsoft gun can fire any gram of BB, although .12g BBs wont be that effective in a sniper, try .25g or even .3g.
I do not know how powerful that gun is but for a sniper you usually want a heavier gram round such as .24, or .26 I believe that is as high as they go.
Not normally. In fact I can not think of any pellet rifle that takes a 16 gram C02 cartridge.
Try .12 grain BB's, and also check your scope (if you have one) also, the wind might have something to do with it .12 grain BB's would make it less accurate. You should try .28 they should work.
I think you mean grams. They come generally in .12 gram, .20 gram, .25 gram .28 gram and .30 gram and a few higher grams than that. Grams are a weight measurement so that should answer your question. Most people use .20 grams in an AEG and .28 or .30 for sniper rifles. 24 caliber I believe means 6mm bbs which is the standard size bb for airsoft.
6mm .12 gram or 6mm .20 gram BB's are recommended.
it depends if you want semi-automatic or not, electric is usually better butt it losses its charge fast. it even goes down when your not shooting! but it is still automatic so i would go with a fully charged electric with 20 gram BBs and a scope.
375 FPS
Yes dro should be 20 a gram
the best way to lower the fps on a sniper rifle would be to reduce the type of spring you are using. airsplat.com has a whole bunch to pick from to decide what type of FPS you're looking for.
a gram of strawberry haze should go for atleast 15 or 20 dollas for a gram makes since!!
