Brass Arms - that one mod that adds random repeaters and stuff to Minecraft.

Brass Arms is a mod that adds a new resource, known as brass, to craft repeaters (or some crap like that it's like 10:44 as I write this) of many different types, such as one that shoots TNT, one that shoots bullets that set things on fire, and more!
