Rugged Suppressors Obsidian Piston 1/2×28

Description

Product Overview

The Rugged Suppressors Obsidian Piston in 1/2×28 is a precision-engineered mounting component, essential for the proper and reliable function of your Obsidian series suppressor on common pistol platforms. Designed for the discerning shooter who demands both performance and durability, this piston serves as the critical interface between your host firearm and your suppressor. Its primary function is to facilitate reliable semi-automatic cycling while managing the gas system, a non-negotiable requirement for pistol-caliber suppressors. Built to Rugged Suppressors’ exacting standards, this 1/2×28 threaded piston is specifically intended for use with 9mm and .357 caliber hosts featuring the ubiquitous 1/2×28 muzzle thread pattern, ensuring a secure and concentric attachment.

Key Features

• Heat-Treated 17-4 Stainless Steel Construction: The piston is machined from 17-4 precipitation-hardening stainless steel and undergoes heat treatment. This process provides an exceptional balance of strength, corrosion resistance, and durability, ensuring long-term service life even under sustained thermal cycling.
• Non-Slotted, Full-Circumference Gas Seal Design: Unlike slotted piston designs, this piston utilizes a solid sealing surface. This creates a more complete gas seal at the piston face, which directly contributes to reduced gas blowback towards the shooter and can lead to a smoother, cleaner shooting experience.
• Optimized for Reliable Cycling: Engineered specifically to support the mechanical cycling of tilting-barrel pistol actions, this piston helps ensure your host firearm functions flawlessly round after round when suppressed, minimizing feed failures and ejection issues.
• 1/2×28 Thread Pitch: This industry-standard thread pitch makes the piston compatible with a vast array of popular pistol hosts chambered in 9mm and .357 Sig, from common service models to competition-oriented handguns.
• Dedicated Obsidian Series Compatibility: This is not a universal component. It is meticulously designed to integrate with the locking mechanism and internal geometry of Rugged Suppressors’ Obsidian 9 and Obsidian 45 models, guaranteeing proper function and safety.
• Stainless Finish: The stainless finish is not merely cosmetic; it complements the material’s inherent corrosion resistance and simplifies cleaning by providing a smooth, non-porous surface that resists carbon buildup.

Performance & Applications

The correct piston is not an accessory; it is a fundamental part of a suppressed pistol system. This 1/2×28 piston enables specific, practical applications for your Obsidian suppressor.

For the home defense or duty-oriented user, installing this piston on a modern striker-fired 9mm pistol ensures that the suppressor system will cycle defensive ammunition reliably. The reduced gas blowback is a significant benefit in close-quarters or low-light scenarios, helping to maintain visibility and focus. For the recreational shooter or competitor, using this piston on a threaded-barrel pistol transforms range sessions. It manages sound signature effectively while the robust design handles the demands of high-round-count training. Furthermore, for hunters utilizing pistol-caliber carbines with 1/2×28 threaded barrels, this piston allows the Obsidian to be employed as a versatile sound mitigation tool across multiple compatible platforms, from handgun to PCC, with a simple component swap.
