Griffin Armament CAM-LOK QD Piston for Pistol Suppressors - Stainless Steel$71.96
Availability: In Stock
The Griffin Armament CAM-LOK QD piston for Sig Sauer SRD suppressors solves a real problem that direct-thread piston users know well: loosening. Unlike fixed single-piece pistons that hand-tighten and gradually work loose under slide cycling, the CAM-LOK system uses a patented taper-lock interface that stays put even as the piston cycles back and forth during firing. The result is fewer surprises at the range and no more constant retightening between sessions.
Built from 17-4 stainless steel and heat-treated to H900 spec, this piston accepts a standard 3/4 socket wrench for installation and removal—a significant practical advantage over hand-tightened designs. The three 120-degree mounting positions let you attach your suppressor quickly without hunting for alignment, and Griffin's manufacturing tolerances ensure minimal point-of-impact shift between positions. If you're running a Sig Sauer SRD suppressor with a CAM-LOK barrel adapter (sold separately), this piston offers the secure, repeatable mounting system that keeps your group tight and your day on track.
The real win: interchangeability. Once you have the CAM-LOK ecosystem set up across different host firearms with compatible barrel adapters, you can move your suppressor between guns without swapping pistons or disassembling the can. For shooters who run multiple hosts, that's a game-changer. System weight mirrors legacy direct-thread alternatives, so you're not adding heft for the convenience and reliability you're gaining.
| Material | 17-4 Stainless Steel |
| Heat Treatment | H900 |
| Mount Type | CAM-LOK QD (Universal) |
| Mounting Positions | 3 (120° separated) |
| Installation | 3/4 socket wrench |
| Suppressor Compatibility | Sig Sauer SRD (with compatible CAM-LOK barrel adapter) |
This piston is designed for Sig Sauer SRD suppressors. Compatibility with other models depends on whether they accept CAM-LOK QD piston systems. Check your suppressor's documentation or contact us if you're unsure.
The CAM-LOK piston works with any 3-lug CAM-LOK barrel adapter. Barrel adapters are sold separately and must be matched to your host firearm's mount interface. Griffin Armament offers adapters for common pistol platforms.
Yes—that's one of the CAM-LOK system's main advantages. As long as the suppressor accepts a CAM-LOK QD piston, you can swap this one between them without disassembly. Different brand suppressors in the CAM-LOK family also support interchangeable barrel adapters.
The internal taper-lock interface between the piston and barrel adapter creates a secure mechanical fit that persists even as the piston reciprocates during firing. Combined with socket wrench installation (rather than hand-tightening), it dramatically reduces the vibration-induced loosening that plagues traditional fixed pistons.
