Franklin Armory Praefector M Features The Franklin Armory Praefector M is built around Franklin s AR-Elite gas system paired with a rifle-length gas block tuned to run reliably across a range of .308 Win loads while reducing bolt carrier velocity for smoother cycling and less wear. A 20 inch medium contour barrel with a 1:10 inch twist stabilizes a wide range of .308 bullet weights for both precision and hunting applications. The Militia trigger group is factory equipped with Franklin Armory s Binary firing system giving the shooter the option to run standard semi-automatic fire or Binary mode which fires one round on the trigger pull and a second on release. A salt bath nitride finished lower and low-profile Triumvir muzzle device round out a rifle built for both performance and durability. A 14 inch FSR handguard wraps the barrel in a lightweight optics-ready package with room to mount lights optics and other accessories along the full length of the rifle. The Magpul PRS stock offers length of pull and cheek height adjustment for a customized fit while the Ergo ambidextrous sure grip gives the shooter a secure hold regardless of firing hand. A bilateral safety selector keeps the manual of arms consistent for right and left-handed shooters. Finished in black throughout the Praefector M combines Franklin Armory s Binary trigger technology with a well-rounded adjustable rifle platform for shooters who want more than a standard semi-automatic AR.
