Innovative piston system and slimline ergonomics

The OSP-16 brings back the Original self-regulating piston system with a reengineered, patent-pending design that smooths the transition between suppressed and unsuppressed firing. Its low-profile piston fits inside an ultra slimline handguard, preserving a tight, familiar grip while still delivering the advantages of a piston-driven MSR.

Handguard and accessory compatibility

The integrated barrier stop and top-side Picatinny rail ensure zero-compromise accessory mounting, while M-LOK compatible slots on all seven sides offer flexible attachment points for lights, grips, and panels without adding bulk. This layout supports both duty and range setups with minimal modification.

Advanced gas management and muzzle mitigation

The new gas block uses multi-faceted dispersion technology to bleed excess gas forward through a gas block vent and evenly around the piston surface, significantly reducing backpressure at the receiver. Each OSP-16 is topped with Franklin Armory’s linear-compensating Triumvir® flash suppressor for reduced muzzle flash signature and improved follow-up shot clarity.

Franklin Armory’s reputation for innovation is evident in the OSP-16’s minimal-maintenance goal: the system is designed to require little to no piston maintenance over a typical barrel lifespan — a major benefit for users who prefer time on the range over time in the shop. Price on the shop page is listed at $1354.99.
