AR15, M16, M4, Ruger Mini 14
m4 <><><> You would have to define better. The M4 has a greater range, the AK a heavier bullet, the M4 a faster bullet, you can carry more ammo for an M4, the AK needs less maintenance, the M4 has a higher rate of fire- and so on.
The standard 5.56 mm cartridge is centerfire. There IS an adaptor to permit the use of .22 LR rimfire ammo for training.
The M4 carbine fires NATO standard 5.56x45mm ammunition. This is often confused with commercial .223 Remington ammo, which is dimensionally similar. However, they are not the same.
It depends on the kind of ammo. A bomb can weight tons of tons of metric tons. A .50 caliber bullet can weigh around a pound.
I use .20g blaster bb's. They are quite expensive, but if you use low quality ammo it will wreck the gun.
I would just get a new m4 mag. They Are cheap and probably isn't worth tryin to fix. How ever it sounds like you have a spring problem with your mag try replacing the spring.
