This is somewhat subjective, but in terms of spherical consistancy, diameter, and other factors, GoldenBall and Bioval are highly rated, especially at higher weights.
In terms of price-to-quality ratio, Crossman serves well at about 15 USD / 5000 BBs, compared to 45 USD / 5000 for GoldenBall. Rice bags of >10,000 reduce the per-pellet cost slightly.
You should get .28gram bb's
The stinger p9 is good with .12 gram airsoft BBs or you can use .25 gram bbs but then it will decrease the range.
Airsoft bbs are made up of plastic and are 6mm in diameter and are .24 cal, BBs however are metal and are .177 cal (4.5mm)
Type recommended by the maker of the airsoft.
The best airsoft MP7 is the WELL brand MP7.
Light .18 gram bbs.
you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
no
"Systema" is by far the best airsoft gun brand out there.
yes they are very accurate
.25 Airsoft bbs can be good. Their weight is very good for accuracy and helps for a harder hit from the bbs. However, no bb is good if they are not high polish. Companies like Madbull and Matrix make good .25 bbs.
