Griffin Armament® Optimus® Micro Taper Mount Interface Adapter – 17-4 Heat-Treated Stainless Steel – Black Nitride Finish – Exclusively for Optimus Micro Suppressors – OPMEXT
Product Description
The Griffin Armament® Optimus® Micro Taper Mount Interface Adapter (OPMEXT) represents a monumental leap forward in micro-suppressor versatility and muzzle device logistics, masterfully engineered in Wisconsin, USA, to bridge the gap between high-performance rimfire/varmint silencers and full-scale rifle hosts. Purpose-built to expand the utility of your NFA collection, this precision-machined interface converts the rear threads of the Optimus Micro suppressor into a standardized taper mount hub. While standard rimfire silencers lock you into traditional direct-thread configurations—which easily vibrate loose over rapid firing loops, causing accuracy-destroying baffle strikes—Griffin’s Taper Mount system introduces an unyielding mechanical seal. This specialized interface module (791154083109) serves as an absolute asset for varmint hunters, precision rimfire target marksmen, and tactical trainer setups looking to standardize their mounting infrastructure.
The core structural and kinematic triumph of this American-built suppressor component lies in its **universal cross-compatibility with all Griffin Taper Mount muzzle devices**. Whether you choose full-sized long flash hiders, multi-port muzzle brakes, minimalist flash suppressors, or compact EZ Brakes across any standard thread pitch, this adapter interfaces seamlessly. Precision-machined from premium 17-4 PH stainless steel and subjected to an advanced liquid-nitriding cycle, the adapter features extreme surface hardness and resistance to harsh gas erosion. The integrated taper geometry automatically centers the suppressor on your rifle's bore axis, self-centering the assembly to eliminate concentricity shifts and secure repeatable point-of-impact (POI) metrics downrange.
The true operational advantage of this upgrade lies in its clever mechanical gas mitigation. Beyond serving as a secure retention footboard, this interface effectively creates an expansion extension volume that helps control gas blowback when shooting on semi-automatic platforms like the AR-15. Weighing a mere **2.5 ounces**, this adapter minimizes front-end muzzle heft, transforming your standard 5.3-inch standard Optimus Micro configuration into an extended, highly efficient 6.8-inch recoil-insulating powerhouse. Completed by a low-friction outer skin that resists heavy carbon caking, this 0.156-pound component grants you total structural authority over your suppressed staging layout.
Includes: (1) Authentic Griffin Armament Optimus Micro Taper Mount Interface Adapter (Premium 17-4 Stainless Steel, Low-Friction Black Nitride Armor Finish, Internal Alignment Shoulders), Packed in Factory Original Branded Retail Distribution Sleeve Packaging.
*CRITICAL SAFETY & COMPLIANCE GUIDANCE: The Griffin OPMEXT adapter is made exclusively for the Griffin Armament Optimus Micro suppressor and will NOT fit or thread into alternative silencer tubes like the Optimus 9, Bushwhacker, or Resistance series. Furthermore, remember that the Optimus Micro suppressor is strictly rated for .22 caliber / 5.56mm projectiles and smaller varmint loads (such as .22 LR, .22 WMR, .17 HMR, .223 Rem, and 22-250 Rem). While this adapter allows your Optimus Micro to thread onto full-sized .30-caliber Griffin Taper Mount muzzle devices, attempting to fire any projectile larger than .224 inches through this suppressor will result in catastrophic failure, permanent silencer destruction, and severe injury. Always visually double-check your firearm caliber prior to seating your silencer loop.*
Key Features
- Universal Taper Mount Interface: Adapts any long or short configuration Griffin Taper Mount muzzle device to fit the rear threads of your Optimus Micro silencer.
- Repeatable Self-Centering Taper: Advanced internal taper architecture ensures absolute concentric alignment with the bore, eliminating point-of-impact shift anomalies.
- 17-4 Heat-Treated Stainless Steel: Solid billet construction provides ultimate thermal stability and immunity to intense blast chamber gas erosion.
- Corrosion-Resistant Black Nitride: Hard liquid-nitride treatment forms an ultra-smooth skin that prevents stubborn carbon baking and facilitates seamless breakdown loops.
- Enhanced Backpressure Mitigation: Creates an efficient rear extension cavity that reduces port-pop and facial gas blowback on gas-operated semi-automatic carbines.
- Minimalist Lightweight Mass: Adds a mere 2.5 ounces to the suppressor assembly, avoiding front-heavy barrel torque to maintain agile muzzle tracking.
