No it's not designed to do it.
No, it is a spring gun.
No. Aspects which determine how powerful an airsoft gun is actually it's spring (stronger/harder the spring means bigger fps), compression (better compression = better fps), and weight of the BBs we use (heavier BBs in the same fps can deliver bigger energy).Edit: If a gun that is automatic in real life is spring and very inexpensive, it is probably cheaply made and therefore almost definitely weak. However, "manual" guns that are spring are usually at least fairly powerful, such as bolt action sniper rifles.
yes they are very accurate
Any airsoft gun. Yes
standard 6mm plastic bbs.
No, if you are talking about bb's for a BB gun. The BB's for an air rifle or BB gun wont even stay in a Magazine for an airsoft gun. Airsoft BB's are 6mm, air rifle bb's are much smaller. You will ruin an airsoft gun with the smaller metal bbs. But you can get aluminum 6mm pellets for an airsoft gun.
Most guns are built for .20 gram bbs, as .12 will be too light and inaccurate Some store brand airsoft guns are measured using .12g BBs because it increases the muzzle velocity due to the light weight. This is done to inflate the real performance of the airsoft gun. .12g BBs are to be used in the following kinds of guns: - Plastic Spring powered pistols - Plastic single barrel spring powered shotguns - Airsoft Grenades - Airsoft "flame throwers" Most airsoft guns use .20g BBs or heavier, not to exceed .25g for most airsoft guns (Many airsoft fields limit you to .20g BBs anyway). The heavier the BB, the more accurate it will be, but the more energy it will take to propel it. In short, use .2g BBs as a starter minimum.
