This video provides a detailed, step-by-step guide for installing the Sons of Liberty Gunworks M89 Mark 10 Heavy Handguard on a large-frame AR-308 platform. It covers barrel nut installation, torque specifications, and the unique mounting system for the handguard, emphasizing proper alignment and avoiding overtightening. The installation is demonstrated on an Aero Precision upper receiver compatible with the DPMS High pattern.

This guide details three critical mistakes to avoid when mounting a rifle optic, using the Leupold Mark 5HD as an example. It emphasizes not mounting to the handguard, selecting correct scope ring height, and ensuring charging handle clearance. Proper mounting is crucial for maintaining zero and ensuring reliable firearm operation.

Aaron Quinn of Cobalt Kinetics details a significant redesign of the AR-15 platform's barrel attachment and handguard mounting system. The core innovation involves inverting threads and elongating the upper receiver to create a more rigid and precise barrel seat, eliminating the traditional barrel nut. This system uses a jam nut and a specifically designed handguard mount to achieve a semi-monolithic interface, enhancing accuracy and consistency by de-slaving the barrel and handguard. The design prioritizes performance and reliability, moving away from aesthetics to focus on a robust, repeatable shooting platform.
