Our Assessment: The ULT AR 57, also known as the AR Five Seven, upper is an aftermarket upper receiver assembly for the AR-15 rifle platform that is designed to be compatible with the 5.7x28mm cartridge. Famously used by the FN P90. This upper receiver assembly is manufactured by a company called AR57 MFG and is designed to replace the standard upper receiver of an AR-15 rifle.
Once installed on the rifle, it allows the use of FN P90 magazines that hold 50 rounds of 5.7x28mm ammunition. These magazines fit into the upper receiver and feed the rounds into the chamber of the barrel, allowing for increased capacity compared to traditional AR-15 magazines. The ULT AR 57 upper receiver also features some unique design elements to increase the overall strength and durability of the receiver.
If you want one of the “coolest” AR-15’s on the market, well, you’re looking at it. Don’t miss out on adding this gem to your arsenal. Great for the range, suppressor options, varmint hunting, or self defense if you’re feeling a little over the top (no pun intended), or maybe you want a gun that resembles the FSS Hurricane from Modern Warfare 2 as this is the gun it was modeled after. Whatever the reason may be, you have to bid on it first! Good Luck!
