Enhancements: New Weapons Grenatelauncher with 4 Types of Ammo Atomic, Highexplosive, Smoke and Incendiary.
Grenates: can be trown with the same effects (Atomic, Highexplosive, Smoke and Incendiary). Ammo for the Grenatelauncher??
Minigun: with Ammodrums that come in in 3 different types Armorpiercing, Antigravity and Normal. I dont think the others would be a good idea because the minigun shots fast and with explosions, smoke and Fire this would cause massive Lag.
Uzi: Fast shooting Gun with the size of the Pistol that uses The same Ammo as Pistols.
Silverbullets: More Damage Against Undead
Silencer: Can be put on any Gun except for the Rocket launcher, reduces the shooting Sound when a Bullet is shot

Bugfixes:
Rocketlauncher Reloads with smoke Rockets Instead of Highexplosive Rockets also the Rockets are then not used up

Fixes:
Add a Black and Whitelist which Blocks can be destroyed by Bullets and which not. Right Now They destroy only vanilla minecraft Blocks (dirt, Grasblock, Ice, Gravel and so on)
Reduce The Radius of the atomic explosives to the half. The loading time was unreal i play with 100 or more mods and it took 30 Minutes to load in the Hole that the atomic C4 made.

Craftingrecipes:
We really Need Crafingrecipes or some new Mobs which carry the Guns and If you Kill them you get the Gun and the associated Ammo.

These Are Craftingrecipes for some Of the current Items in the mod

Ammo Craftingrecipes : Normal Ammo: Iron, Incendiary Ammo: normal Ammo and a Firecharger, Explosive Ammo: Normal ammo and Gunpowder, Antigravity Ammo: Normal Ammo and a material that is close to Antigravity From another Mod. Rocketlauncher ammo : TNT and Iron. Atomic explosive: Uranium Ore From any Mod and The normal Rocket. Incendiary Rocket: Firecharger and Normal Rocket. Smoke Rockets are a bit Difficult maybe you can go too a Campefire and collect The Smoke with a glassbottle and then use it to make smoke Rockets. C4: Redstoneblocks and TNT.

Gun Craftingrecipes: Gunparts that are made with iron and other stuff to make the guns (for example the barrel or the scope for the snipers with glass and iron).

Hope this is not too much for you. I am From Germany so sorry for bad English or Parts you don't understand properly. Love your Mod have a Nice Day.

Thank you so much for the advices! Will definitely add those features in the future!
