Modernizing My .300 Blackout AR-15 | Easy DIY Upgrades for a Better Build

Welcome to G Moore Life! In this video, I’m giving my old .300 Blackout AR-15 a much-needed upgrade to bring it up to modern standards. I’ll walk you through each part I’ve added, including a new lightweight handguard, a KAW Valley adjustable gas block, a smoother trigger, anti-walk trigger pins, an ambidextrous safety selector, and a better charging handle. These upgrades improve handling, reliability, and overall functionality—whether you're building a new rifle or giving new life to an older setup. No installation or modifications are shown, in accordance with YouTube’s firearm policy. If you're thinking about upgrading your AR-15, this video will give you some solid ideas to consider.
