you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
Not recommended, ever.
All airsoft guns usually use 6mm BBs, usually made of plastic, and come in a variety of different weights (.12 grams, .20 grams, .25 grams, .28 grams). Normally .12 gram BBs are the cheapest, and are good for most airsoft guns, although airsoft guns that shoot at higher velocities should use .20 or .25 gram BBs, as they will shoot straighter.
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.
Low powered guns shoudl use .12 gram or other lighter bbs, medium AEGS shoudl use 20 or slightly higher. High powered spring guns should use 28+ grams bbs.
No, they are too small and will jam the gun. Never try to use metal bbs in airsoft guns or vice versa.
No, airsoft guns are toys. They use batteries and gearboxes to fire 6mm plastic bbs at an average of 2 joules. Although many high powered air rifles can be as dangerous as real guns, they should not be confused with airsoft guns.
no. infact there are airsoft guns made to do that. it only makes the fire rate slow for that particular shot.
Which one is more expensive? Your airsoft guns or BBs? Buy only good quality BBs!
Yes. .12 grams is the weight of the BB, not the size. Almost all airsoft guns use 6mm BBs. .20 gram BBs are heavier and reduce distance and velocity, but increase accuracy. .12 gram BBs will fire with more velocity, but there will be more spin on the BB and less accuracy.
no
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.
The stinger p9 is good with .12 gram airsoft BBs or you can use .25 gram bbs but then it will decrease the range.
