Our Favorite .300BLK CQB Loadout (Sig MCX Tacops)
This review details a custom Sig MCX Tacops build optimized for .300 Blackout CQB. Key features include a 6.75-inch barrel with a 1:5 twist, Dead Air Sandman K suppressor, Modlite OKW, L3Harris ATPIAL-C with a diffuser, Unity Tactical controls, and an EOTech on a Wilcox riser for night vision use. The build emphasizes fast reloads with an HRF RCM Magwell and uses Hornady 208gr subsonic rounds.
