BBMB stand for "Bipods Barrels & Muzzle Breaks"
Here's a snap shot of the barrel/bipod attachments I've made. Increases damage dramatically, and reduce weapon sway when crouched(hopefully we will have prone soon?). When the barrel is a attached it switches to a larger round, with much more bullet drop, and damage.
The muzzle break will also function as a damage mod, and well as recoil reducer(of course). I will make this attachment available for MOST rifles, and pistols!
I'll post pictures of the muzzle break as soon as I'm happy with the texture!
Still only tested in RETAIL 1.1 patch.
