The Franklin Armory Reformation RS7 .300 Blackout is a 7.5-inch AR-pattern firearm built on Franklin Armory’s patented NRS barrel, with straight-cut lands and grooves instead of conventional rifling (brand part no. 00-10047-BLK). Franklin Armory designed the Reformation as a short, stocked home defense gun with yawing projectiles and reduced over-penetration. This .300 Blackout version runs a Custom Tuned Trigger, a Triumvir muzzle device on a 5/8-24 thread and a B5 Systems Bravo stock with a P-Grip and VFG. A 7-inch FST M-LOK handguard and an optic-ready upper leave room to set it up with a light and a red dot.
