Rifles Descriptions

5.56x45 - 62 Grain FMJ M855 - Winchester - 150 Rounds

This 5.56x45 cartridge by Winchester isn’t your run of the mill FMJ. It’s an M855, also known as the SS109 or “penetrator.” The penetrator projectile’s slightly greater weight gives it a higher sectional density than a conventional 55 grain bullet, but that’s not the only reason why it penetrates so well. This bullet’s green tip indicates that it ends in a seven grain steel spike, which enables it to reliably pierce a 0.12” thick sheet of steel well beyond 600 yards. For armored or vehicular threats, the penetrator is the bullet for the job. This NATO spec cartridge offers all the high quality components that you should expect from a revered manufacturer like Winchester. This round features a reloadable brass shell casing, drawn and tapered to specific dimensions for unfailing feeding, chambering, and extraction. Its new-fashioned Boxer primer won’t permit corrosive salts to accumulate in the chamber and bore, and its propellant burns up clean to deliver consistent ballistic performance. Please Note: While they share the same dimensions, the 5.56x45 is loaded to a higher pressure than the 223 Rem. Do not fire this ammo in a weapon that is chambered solely for 223 Rem.

Bushmaster Gas Piston 90294

The Bushmaster Gas Piston System Rifles bring new levels of reliability to the “AR” type rifle platform by eliminating carbon build up, gas leaks and heat within the Upper Receiver. The Gas Piston System operates by tapping gas pressure off the barrel much like the systems found on AK-47s and FALs * Functions with a wider range of ammunition - less gas pressure - lower cyclic rate * Offers improved reliability and control - with cleaner operation and reduced recoil * Keeps carbon build up and powder residue from reaching - and fouling the Upper Receiver and Bolt Carrier * A Detented Plug in the Gas Block allows easy cleaning of the Systems’ Hard Chrome Plated Piston
