Barrel: A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as "Machine Gun Steel" by virtue of its required use in FN's M249 and M240 weapons. The hammer forging process work hardens the steel, making it more durable. In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability. Chambered in .223 Wylde, with a 1/8 twist, M4 barrel extension, and a Rifle-length gas system. This 18" A2 profile barrel is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected. The barrel is finished off with a 15" PSA Lightweight M-Lok free float rail and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is hard coat anodized black for durability. Featuring T-marks, these upper receivers are made for us right here in the USA.

Each upper is assembled to order with US-made parts, and test fired to check gas function.

I'm just saying... Why buy this when you can buy a full Ruger MPR 18" for around $680?

You have a good point. Unless you are a SOT dealer or own a pre 86 full auto M16 who enjoys shooting full auto all the time with a SPR upper.

Wait until this Covid-19 madness is over and the MPR can most likely be had for $600 or less. I own two of them and love these rifles. I purchased the American Flag cerakote MPR for $614.00 shipped in mid Dec 2019 and the standard version MPR for $559.99 shipped in late Sep of 2017.

I want one of these so bad, but I've already exceeded my gun budget for the month
