I, have personally made two threads about this.
But lets make this happen >o<
sights, scopes, underbarrels, extended mags, stocks, silencer, all those goodies.
silencer would just be a decorative feature.
underbarrel shotgun.
underbarrel grenade launcher.
underbarrel flamethrower.
scopes would add accuracy.
extended mags is self explanitory.
stock reduces freeze? or less recoil for the M60, M249, MG36? we should add recoil to more guns so they are more encouraged to buy the stock / foregrip / bipod.
Full metal jacket adds +1 damage.
select fire: this is probably going to be the coolest one on the list =D. it basically allows you to change between full auto, semi auto, 3 round burst etc.
Speed reloader? i could see this one implemented.
slug rounds for shotgun, shoots one deadly round that does all the pellets' damage stacked into one. ( pbp shotgun as an example: 4 pellets that deal each 3 damage. with slug rounds: one 12 damage shot. )
tactical knife: similar to bayonet on the M1 carbine and the neo rifle
flashlight: essentially a decoration. but maybe we could release a "dark spar" that you can only participate in with a flashlight. ( I would be so damn hyped about this )
thats about it for my ideas.
sorry if i took over your idea mate.
