FN 15™ SRP

Available for law enforcement sales only.

The FN 15™ SRP is designed to be high performance and optics-ready, perfect for departments and agencies looking for a base rifle to customize to their liking. The rifle includes many of the same features found in the FN 15™ series, like a 16-inch alloy steel button-broached barrel, 6-position collapsible stock, A2-style compensator, and sling attachments. In contrast, the FN 15™ SRP features an optic-ready MIL-STD-1913 flat-top rail for mounting the scope or sight of your choice.
