Rugged Suppressor OP004 Piston M13.5x1 LH Copper 17-4 Stainless

The Rugged Suppressor OP004 Piston delivers precision-engineered reliability for suppressor systems requiring M13.5x1 left-hand threading. This copper and 17-4 stainless steel component ensures consistent lockup and optimal gas seal performance across extended firing schedules.

What Makes This Different

The OP004 combines copper's superior heat dissipation properties with 17-4 stainless steel's corrosion resistance and strength. Unlike standard pistons that rely on single-material construction, this hybrid design manages thermal stress more effectively while maintaining dimensional stability. The M13.5x1 left-hand threading provides secure attachment that tightens under firing rather than loosening.

Key Features

• M13.5x1 left-hand thread pitch for secure suppressor attachment
• Copper construction for enhanced heat transfer and gas sealing
• 17-4 stainless steel components resist corrosion and wear
• Precision machined tolerances ensure consistent suppressor alignment
• Compatible with Rugged suppressor systems and select third-party models
• Heat-treated surfaces provide extended service life
• Factory specifications meet SAAMI dimensional standards

Field performance remains consistent across temperature extremes and rapid-fire sequences. The copper material conforms to barrel crown irregularities, creating an optimal gas seal that maintains suppressor efficiency. Competition shooters benefit from the consistent point of impact, while tactical applications rely on the piston's ability to cycle reliably under adverse conditions.
