Most average to good guns take these bbs. They are heavy enough not to be affected by the wind very much and are quite accurate. They slightly lower the fps of the gun but the bb weight increases inertia so they accually INCREASE the "punch" of the gun. Also, .20g bbs are made much better quality than .12 because they have to stand up to the internals of more powerful guns.2000 Rounds of 0.2g ammunition from Excel, 6mm, industry standard.These BB?s are perfect for gaming, although not 100% biodegradable Excel say their BB?s are ?designed from an ecological view point?. Excel 0.2g BBs, 6mm, give the best results and are used by professional and novice players alike.
