We love fancy donuts. Offer us a raspberry jelly filled triple chocolate Long John with honey glaze and nonpareil sprinkles and we will gladly accept. But there’s nothing wrong with plain cake donuts, either. Sometimes it is good to keep things basic, which you can do with your AR-15 rifle if you order this big loose-packed case of 5.56x45 ammo by Federal!

This is an M193 cartridge – XM193, technically, because it was manufactured specifically for the civilian market. That means it launches a 55 grain bullet at a muzzle velocity of 3,240 fps, which is the gold standard for AR-15s in terms of ballistic performance. It’s a simple enough bullet, with a jacket that hardens it and a boat tail that makes it more aerodynamic. We recommend this type of bullet for range training, although it’s also a suitable option for self defense.

This ammo was loaded for Federal at the Lake City Army Ammunition Plant. That means it has military-grade primers, propellant and brass. The brass cases are brand new, with visible annealing marks because they were treated for superior durability at the factory.
