Griffin Armament | CAM-LOK Universal Piston for SIG SAUER SRD

The Griffin Armament CAM-LOK universal piston is the bronze-colored piston component designed for use inside compatible Griffin suppressors. It converts legacy direct-thread pistons to a rapid, secure CAM-LOK quick-detach interface for pistols fitted with a 3-lug CAM-LOK barrel adapter. The CAM-LOK interface emphasizes repeatable concentricity and a taper-lock engagement to reduce common end-cap and baffle strikes associated with hand-tightened direct-thread pistons.

Typical applications include precision range use and competition where fast, repeatable suppressor mounting and minimal point-of-impact shift are priorities. The piston is the component installed in the suppressor; barrel adapters are sold separately.

Product Specifications

• The item is a CAM-LOK universal QD piston intended for use with 3-lug CAM-LOK barrel adapters.
• The sold component is the piston (the bronze-colored part installed in the suppressor).
• The interface provides three mounting positions separated by 120 degrees for rapid alignment.
• The piston accepts installation with a 3/4″ socket wrench and is intended for prevailing-torque installation.
• The taper lock interface is designed to drastically reduce or eliminate baffle and end-cap strikes.
• The piston is specified as H900 heat treated to improve durability and wear resistance.
• The material is listed as 17-4 stainless steel in manufacturer documentation.
• The design maintains total system weight identical to legacy direct-thread pistons when used as part of the CAM-LOK system.
• The CAM-LOK pistons are universal across pistons that accept 3-lug CAM-LOK barrel adapters, enabling interchangeability between supported suppressor models.
• Manufacturing accuracy is held to Griffin Armament’s standards for squareness and concentricity to minimize POI shift between mounting positions.
• The piston supports interchangeability with other CAM-LOK barrel adapters and is compatible with universal QD piston barrel adapters (adapters sold separately).
• The manufacturer notes the piston reduces the need for repeated torque checks versus traditional hand-tightened direct-thread pistons by locking via taper engagement.
• The supplier lists the weight as .15 (units not specified by the manufacturer).
• The UPC is 791154085196.

This piston is a practical choice when you need a repeatable, tool-installed mounting interface for a CAM-LOK-equipped pistol setup. Its taper-lock geometry and precision manufacturing focus on alignment and longevity rather than temporary hand-tight engagement, making it useful for shooters who prioritize reliable attachment and minimal maintenance between sessions.
