Griffin Armament is proud to introduce DUAL-LOK our newest QD mounting system for rifle suppressors. The DUAL-LOK system is comprised from two parts the DUAL-LOK Mount and the DUAL-LOK muzzle device (of your choice). This page is for the DUAL-LOK Titanium Minimalist Brake. - The muzzle device integrates 60 machined mounting position grooves which is doubled by the mount's two locking positions hence the double entendre DUAL-LOK. How is this achieved• The mounts' two locking positions are machined out of phase of one another by 3 degrees which provides the 120 effective locking positions and ensures a tightly mounted and locked suppressor. When the suppressor is installed only one of the two positions will generally function by allowing the spring to push the locking collar rearward over the splines. - Constructed of 17-4 PH stainless steel the DUAL-LOK Minimalist Brake has a wear resistant baffle that increases suppressor service life. Additionally the brake features compensating ports that help reduce muzzle climb while assisting in reducing felt recoil. The Minimalist Brake weighs 2.6 ounces and is less than an 1.5 long adding minimal weight and length compared to that of most competing suppressor mounts. The lighter weight reduces suppressor system weight while making the host firearm barrel lighter and more responsive to the shooter. Each brake comes with a shim set for timing. - The 6.5mm option allows for optimal braking performance and sound performance with a suppressor on 6.5 grendel 6.5 creedmoor 260 remington 6.5x47 Lapua etc. - Diameter: 1.07 [grooves] .93 [unit] - OAL: 1.42 - Weight: 2.3 oz - Materials: 17-4 Stainless Steel - Finish: QPQ Nitrided - Key points : - Utility patent pending - Wear free mounting system requires no consumable parts - Taper lock interface ensures security and accuracy - 120 effective positions ensure a rock-solid suppressor mount and provide extremely low POI shift - Sacrificial baffle to extend the service life of your silencer - Lighter than most market competitive suppressor mounts - 17-4 PH Stainless steel - Nitrided for increased surface hardness corrosion and wear resistance - ¾ wrench flats on muzzle devices - Shim set Included
