Specifications

Manufacturer: Kratos Design Group

From the manufacturer

The Kratos Design Group MLOK QD Sling adapter is CNC machined from 4140 steel and black nitrided. The 4140 material boasts a tensile strength of 95,000psi making it extremely durable and able to withstand years of abuse. Our QD MLOK Sling Mount is 4-position rotation limited, includes MLOK hardware and is backed by our lifetime warranty. 100% made in the USA. The included MLOK hardware uses nitrided MLOK nuts and screws with a tensile strength of 170,000psi. Strength is in our name and we apply that philosophy to every aspect of our products. The MLOK screws require a 5/32 Allen wrench (not included). The included screws have thread locker pre-applied. We recommend a torque value of 30-35in/lbs for mounting on aluminum handguards. A torque value of 12-15in/lbs is recommended for Magpul polymer handguards.
