Add some armor plates, markings, and other stuff like that.

But against other nations, they act kinda like how ISIS treats their enemies.

Doesn’t matter. The strongest of people will always struggle to control the recoil of the M4A1 despite how small the round is. Guns without recoil depends completly on how the are built and how good the user is at controlling recoil. People one hand guns all the time. I’ve seen people one hand the M60 light machine gun. Only drawback is how hard it is to aim.

Yeah. Basically all the foreign countries in the world.

Use the NBC veteran vest as an example.

With that the recoil of your gun might be balanced by the weight, but the size of a flak cannons round even shakes and gun even when it’s more than 200 pounds.

Most guns have no problem penetrating steel, it’s really just the problem of penetrating thick steel walls. And in order for guns to have more penetration to pierce through thicker and stronger walls, the points have to be sharp, but also have a larger caliber. If your gun is stupidity large, then it either has to have and advantage of caliber size, capacity, recoil control or fire rate. In your case it is caliber size. With a stupidly large gun, you will stuggle to aim it and carry, let alone control the recoil. For example. The 50 caliber round can penetrate concrete walls, steel beams and entire vehicles. With that, 50 caliber rounds have the disadvantage of powerful recoil. The recoil of the M107 50 caliber sniper rifle can dislocate your shoulder. But it has one hell of a devastating shot that will blow limbs off with ease.

Alright, I might still use your current for a little bit longer cause it’s just odd to have a random change in design.

Theres a MG version of the SA80 assualt rifle but I can’tput my finger on it’s name. It’s like a drum fed bullpup rifle and it’s a pretty nice gun.

Damn that’s perfect.
