ALG Defense, Inc. Quality Mil-Spec Single Stage AR-15 Trigger - Curved

The ALG Defense Quality Mil-Spec (QMS) Trigger upgrades a standard AR-15 fire control group with smoother operation and genuine reliability, giving shooters mil-spec compliance without the grittiness common to basic factory triggers.

Features:

• Single-stage trigger built to standard mil-spec sear geometry for maximum reliability
• Pull weight of approximately 6.5 lbs, compliant with M4/M16 military standards
• Constructed from mil-spec 8620 alloy steel and 1070 high-carbon steel
• Trigger and hammer pins made from durable 4140 chrome-moly steel, ground 0.001" over standard to reduce play
• Corrosion-resistant springs paired with a full-force hammer spring for reliable ignition
• No matched parts required, since components are fully interchangeable for easier maintenance

Because the QMS keeps standard sear geometry rather than a specialty cassette design, it installs with standard AR-15 spare parts and procedures, giving armorers and duty rifle owners a genuine reliability upgrade without deviating from familiar mil-spec installation.

ALG Defense assembles the QMS trigger in the USA, backing it with the reliability standard the company has built its reputation on for duty and armorer-grade AR-15 parts. That reliability shows up range trip after range trip, build after build. It's a genuine upgrade for anyone looking to improve their factory trigger feel.
