Griffin Armament 24mmx1.5mm thread adapters provide compatible AK platforms with precise 5/8x24 threads, ensuring a secure and accurate fit. These are not standard hardware store-grade adapters but precision-engineered components designed for superior alignment and durability. Featuring a raised surface that interfaces directly with the muzzle face of the barrel rather than the front sight base, they deliver significantly improved theoretical alignment accuracy compared to the loose, detented alternatives commonly found on these systems. Designed for rifles with clean muzzle faces that are perpendicular to the bore, these adapters should be installed with 50 ft-lb of torque. For optimal performance and safety, professional gunsmith installation and alignment checks are strongly recommended before suppressor use. Integrated 27mm wrench flats ensure easy and secure installation.
