This new Franklin Armory M4 rifle is truly phenomenal and is sure to turn heads at the range as it shoots just as good as it looks. This M4 features an FAI-15 lower receiver, which includes one of the most exceptional features on the rifle...the BFSIII Binary Trigger System! The BFSIII is a 3-Position Trigger. In addition to Safe and Single Fire, in the third position (Binary Fire), it will fire 1 round on Pull and 1 round on Release. This firing system makes it one of the fastest semi-automatic triggers on the market! The BFSIII is ideal for Tactical and Competition use. The BFSIII provides significantly reduced split times between rounds and the ability to place two separate shots into a tighter group. But that is not all folks, the mad scientists at Franklin Armory have added other great features to this rifle which makes it truly one of the best "bangs for your buck" on the market to date. The upper receiver on this M4 is constructed of 7075 T-6 and features a 16" 1:7 twist LTW Contour barrel that is more than capable of producing sub MOA groups with the premium ammunition. Another great addition is the mid-length gas system, which is perfectly tuned to the rifle and ensure reliability, lower recoil, and controlled ejecting. Covering the barrel is a 15" M-LOK capable FST free-float rail that is ready to accept any accessories of your choosing. The Bolt carrier group on this rifle is also salt-bath nitride making it incredibly resistant to wear and corrosion. With all these incredible features, and at near entry-level rifle price, you cannot go wrong with this fantastic Franklin Armory M4!
