Syrac Ordnance AR-15 Low Pro Fully Adjustable Gas Piston System

Mounting Solutions Plus (MSP) has expanded its Syrac Ordnance AR-15 parts inventory in a big way.

MSP, which both produces and distributes hundreds of firearms products, has added the Syrac Ordnance AR-15  Low Pro Fully Adjustable Retro Fit Gas Piston System to its growing lineup.

The new Syrac Ordnance Gas Piston System replaces the standard AR-15 impingement gas system. It features a gas adjustment screw that is accessed from the front of the gas block with an Allen Key (included).
