Airsoft Eliet, G&G, Echo1, MadBull, KSC... from personal experience G&G's are the best and the most affordable but that's just one man's opinion.
.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.
Which one is more expensive? Your airsoft guns or BBs? Buy only good quality BBs!
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 stinger p9 is good with .12 gram airsoft BBs or you can use .25 gram bbs but then it will decrease the range.
you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
With a high-capacity mag, the BBs are stored in a big compartment in the mag, and when you wind it, the BBs are put into a tube leading to the mag well. If you don't wind their mags, they have no BBs to shoot.
no
I do not know of a production airsoft gun that shoots bbs of those dimentions but it doesnt mean its not out there As you probably know, most common is 6mm, and some airsoft guns, specifically some revolvers, shoot 8mm bb's, but I have never heard of a 7mm bb or a gun that shoots it.
yes they are very accurate
Yes and No. If you bought those eco BBs from a sports store like sports authority, then the bbs cannot handle the pressure of your gun. It will shatter in the inner barrel and cause massive jammings. If you bought those bbs from a reputable airsoft store such as airsoftpost or airsoftgi, then the performance will not change. Anyways, you shouldn't be playing at your house, you should be playing at a licensed airsoft arena.
Yes
