Discover More About This Historical Rifle Brass 

Carbine 30 brass was developed for the US military during the 1940s. It was used not only in the full auto M2 Carbine but in the M1 version as well. This was the top choice for soldiers during World War II. 

Diamond K Brass sells high-quality rifle and pistol brass cartridges. Keep in mind that none of our cartridges come loaded. You'll have to process and load the brass cases to be able to fire them in your firearm.
