Give your duty or defensive carbine a crisp, confidence-inspiring trigger without sacrificing reliability. The Rise Armament BLITZ Defense is a single-stage hybrid AR trigger tuned to a 4.50-lb draw weight and housed in a distinctive blue aluminum cassette with a black trigger shoe. Built for the AR-platform, this drop-in unit delivers a clean break, short reset, and consistent pull shot after shot. Whether you’re tightening split times on drills or demanding dependable performance in harsh conditions, the BLITZ Defense provides the control you want with the durability you need.

Why Choose the BLITZ Defense Trigger

• Single-Stage “Hybrid” Feel: A smooth, short take-up flows into a distinct wall and crisp break, minimizing over-travel and improving shot calling.

• Duty-balanced 4.5 lb pull: Optimized for defensive and patrol carbines—light enough for precision, robust enough for gloves and real-world use.

• Fast, tactile reset: Short, positive reset supports rapid follow-up shots and tighter cadences on controlled pairs or transition drills.

• Drop-in convenience: Self-contained cassette installs quickly in AR-15/AR-platform lowers; included pins simplify the swap.

• Built for the grind: Precision EDM/CNC components, heat-treated internals, and a rugged anodized blue housing shrug off carbon, sweat, and hard range days.

• Clean, flat-shooting control: Tuned geometry helps reduce trigger press disturbance, keeping your reticle steady for better hits from 0–300+ yards.
