Quality Once-Fired .223/5.56 Brass

Diamond K Brass only uses the highest quality brass and supplies for our .223/5.56 once-fired rounds of ammunition. Depending on what online retailer you choose, there’s a chance that you may end up with asymmetric, uneven brass casings that can lead to gun jams and other malfunctions.

The most obvious reason to choose once-fired brass is the fact that you can save big when you’re ordering a box of bulk ammo reloading supplies.

If you choose Diamond K Brass once-fired .223/5.56 brass, you can get boxes of 500, 1000, or 2500 for far less than you’ll be able to get a box of new ammo at your local gun shop.
