4140 Armory 5.56X45MM Introduction

4140 Armory is a Marine Corps veteran-owned ammo manufacturer based in Texas. The company entered the ammunition market in 2022, focusing on popular rifle and pistol calibers.

Today, we gave a close look at the 4140 Armory 5.56 Bulk Pack.
These specific rounds are loaded with a 55 grain Full Metal Jacket bullet, making it a great choice for bulk ammo.

After running hundreds of rounds of this 4140 Armory today, I have no complaints. Each round ran clean and accurate. With 4140 Armory being relatively new, they have proven they are a prominent competitor in the ammunition market. I would highly recommend taking this ammo out for your next range day.
