Converted 300 AAC Blackout Brass

Converted 300 AAC Blackout Brass - Military Headstamp

  • $124.99

This brass is formed from Once Fired US Military 5.56mm Brass purchased directly from the Military.

The majority of the headstamp is LC (Lake City) with the remainder made up of WCC (Winchester Cartridge Company / Winchester Military), TAA (Taiwanese NATO Military Supplier) and FC (Federal Cartridge / Federal Military).




All of the brass goes through a pre-selection process where we screen and sort out discolored cases. After the pre-selection, the brass gets washed and dried, ready to be processed. The brass runs through several stages on different machines that check the cases for foreign objects, de-primes, and swages the primer pockets to remove the primer pocket crimp and checks for ringers and crimp removal.

After the initial processing, the cases get lubed, trimmed and sized. Additionally, we size the case opening. Our equipment keeps tolerances within 0.003 at high production rates. After the final forming and trimming, the brass gets another wash, at which all lube is removed and the brass is brought to a shine. The brass gets polished without media, so none of the cases will have dust residue.

We inspect every case that we convert and nothing leaves the warehouse without being visually checked. Just in case, we add 1 extra case for every 100, so in case that your standards may be higher than ours, you have something to cover that.

Our brass will run through your machines just like new brass.
