The Franklin Armory Reformation RS7 (brand part no. 00-10047-BLK) is built around Franklin Armory’s patented NRS (Non-Rifled Straight-cut) barrel, a design that lets this AR-pattern firearm run a 7.5-inch barrel while remaining classified as a non-NFA firearm under the GCA rather than a short-barreled rifle. Chambered in .300 Blackout, it delivers practical ballistic performance with both subsonic and supersonic loads despite the compact barrel length. The B5 Systems Bravo collapsible/folding stock and P-Grip set give it enhanced ergonomics and control in tight spaces. This is a purpose-built compliance solution for shooters who want short-barrel handling without a tax stamp.

Frequently Asked Questions

Does the Reformation RS7 require a tax stamp? No. Its NRS straight-cut barrel is not rifled, which keeps it classified as a firearm rather than a rifle under the GCA, so the 7.5-inch barrel does not trigger NFA short-barreled-rifle rules.

Does the straight-cut barrel hurt accuracy? The NRS design is engineered to retain practical ballistic performance with .300 Blackout ammunition despite the lack of traditional rifling.

Can the stock fold for storage? Yes, the B5 Systems Bravo stock both collapses for length of pull and folds for a more compact package.
