Griffin Armament® DUAL-LOK® Paladin® Muzzle Brake – 18x1mm RH Thread Pitch – .30 Caliber/7.62mm – Black Nitride – DLPB30C181RH
The Griffin Armament® DUAL-LOK® Paladin® 2-Port Muzzle Brake and Suppressor Adapter (DLPB30C181RH) represents an elite mechanical engineering milestone in recoil mitigation and suppressor attachment infrastructure, meticulously developed by military veterans to enhance heavy-recoil tracking loops. While standard muzzle brakes often introduce massive bulk, require tricky timing washers that warp under intense heat, or utilize friction-only quick-detach methods that can back off across heavy firing sequences—the Griffin DUAL-LOK interface completely overhauls tracking safety. This premium muzzle device (689396838185) integrates two highly efficient expansion ports alongside an active, anti-rotation locking spline matrix, establishing a rock-solid primary asset for large-bore tactical carbines and precision European bolt-action rifles.
The structural foundation of this high-performance muzzle adapter is precision CNC-machined from a monolithic block of premium 17-4 PH stainless steel. Celebrated throughout aerospace and defense manufacturing for its incredible structural yield strength and resistance to gas erosion, this core is treated with an advanced **Melonite QPQ (Black Nitride) finish**. This deep chemical hardening lowers the surface coefficient of friction and protects the underlying metallurgy from aggressive, high-velocity carbon cutting and corrosive ammo salts. The defining technical edge of the DLPB30C181RH configuration is its factory-cut M18x1mm Right-Hand metrics internal thread pitch paired with a loose, multi-caliber .30 Caliber (7.62mm) safe internal bore. This specialized footprint allows shooters to anchor the brake straight onto popular European precision precision rifles (such as Sako, Tikka, and Accuracy International) that utilize heavy-profile metric muzzle threads.
The true operational highlight of this tactical workhorse lies in its combined muzzle flat performance and active-locking DUAL-LOK suppressor synchronization. The Paladin geometry integrates **two rearward-directed gas ports coupled with vertical compensation slots**, driving expanding muzzle blast outward and upward to eliminate vertical muzzle rise while flattening horizontal recoil loops. When running unsuppressed, the ports act as sacrificial baffles, absorbing the brunt of initial kinetic friction to extend the operational lifespan of your internal silencer core. Outfitted with precision-milled **DUAL-LOK external locking splines** that mesh with a dual-cam active-locking gate interface, this 2.50-ounce compact adapter delivers absolute mechanical security, ensuring your **Griffin DUAL-LOK 5, DUAL-LOK 7, or PSR suppressors** remain locked down tight without any ratcheting parts to wear out over time.
Includes: (1) Griffin Armament DUAL-LOK Paladin 2-Port Muzzle Brake (.30 Caliber Bore / M18x1mm RH Threads), Precision Multi-Thickness Muzzle Device Shim Kit, Thread Protector Cap, and Factory Protective Retail Box.
*DUAL-LOK Muzzle Device Installation & Alignment Guidance: To secure flat-shooting compensation profiles and ensure a perfectly concentric alignment path for your silencer, the Paladin brake must be timed to your barrel using the included multi-thickness shim kit. Never use a standard crush washer for NFA suppressor-adapter mounts, as crush washers can compress unevenly and cause catastrophic baffle strikes. Clean and degrease all barrel threads, dry-fit the shims until the ports align flat horizontally, apply a drop of high-temperature thread locker, and torque firmly to factory specifications (30-35 ft-lbs).
Key Features
- Dual-Port Paladin Comp Geometry: Two rearward-angled blast ports matched with top vertical stabilization ports fully tame heavy recoil impulses and muzzle flip.
- Native DUAL-LOK™ Suppressor Interface: Precision-cut external locking splines provide a fast, repeatable active-locking connection line with Griffin’s premium DUAL-LOK silencer family.
- Premium M18x1mm RH Metric Threads: Purpose-built to thread directly onto heavy precision European rifle barrels like Tikka, Sako, and Accuracy International platforms.
- Hardened 17-4 PH Stainless Steel: Indestructible aerospace-grade steel base withstands severe pressure wave scaling and intense thermal gas cycles.
- Wear-Resistant Melonite QPQ Finish: Ultra-hard black nitride finish safeguards your muzzle threads from carbon buildup, scratch lines, and environmental moisture.
- Sacrificial Baffle Architecture: Dual expansion faces intercept initial high-velocity hot unburnt powder grains, protecting the internal baffles of your attached silencer from erosion.
