A common mistake from airsofters is that they expect to be able to buy a gun with a good battery. This is really due to all the china manufactured guns that include mostly garbage batteries with their 'packages.' In the past, guns like TM and ICS never included anything other than the gun.
If the g&g has a mechanical blowback, that will use up the battery a good bit faster. When looking for a gun, you should just consider any included battery as a test battery or a throw away in some cases and then buy a better battery or use a good one that you already have.
Why don't you just get an RIS for the classic army 'gf15?'
