The AGM stubby killer is a great gun for CQB. It has a solid metal body and pretty solid internals. The upgrades for this gun is wide in variety with some exceptions. Out of the box the gun comes around 350 fps and shoots pretty accurate and far for being a CQB gun.
Full metal (excluding the stock and grip)
Solid outer body
great out of the box gun
The hop up broke two days after i got the gun.
Other than that its a great gun and recommend buying it for CQB.
