"AR-15" Project. Upgrading a CMMG rifle in AAC 300 Blackout. I removed the factory sight and handguard. Added a Daniel Defense modular floating handguard. Added a Magpul MBUS front backup sight. Installed a LaRue Tactical SPR / M4 Scope QD Mount (LT104) -- Quick Disconnect scope mount. Optics: Leupold VX-R 1.25-4 HOG scope with illuminated, "Pig-Plex" reticle. For night hunting wild hogs, it carries an Elusive Wildlife Technologies XLR-250 LED light. Future upgrades planned to replace the "flash hider" with a more effective suppression device; add a foregrip below the rail guard; install a forward sling swivel to replace the one lost when I removed the factory front sight.
