Build a lightweight precision bolt gun with Caleb from Brownells in this full bench-side walkthrough. In this video, Caleb assembles a 6.5 Creedmoor rifle around the Aero Precision Solus LT action, showing how to install the trigger, torque the barrel, check headspace, fit the action into the MDT HNT26 chassis, mount an Area 419 muzzle brake, and level a Leupold Mark 4HD optic. Along the way, he covers torque values, component choices, and practical setup tips for building a lightweight long range hunting or precision rifle.
This build features premium precision rifle parts, including the Aero Precision Solus LT lightweight action, MDT HNT26 folding chassis, Proof Research pre-fit barrel, TriggerTech Special trigger, Area 419 Hunt rings, Area 419 muzzle brake, Leupold Mark 4HD scope, and MDT CKYE-POD Gen 2 Lightweight bipod. If you are planning a custom bolt action rifle build, this video gives you a start-to-finish look at the process and the details that matter.
