TorkMag Dual-Spring AR-15 Magazine - 40 Round

Features

1. 40-Round Capacity — Holds 40 rounds of 5.56x45mm NATO or .223 Remington in a body only marginally longer than a standard 30-round magazine.
2. Patented Dual-Spring Feed System — Two opposing springs balance torque on the follower to eliminate the bolt-over-base and nose-dive failures that plague conventional high-capacity mags.
3. Self-Leveling Follower — Equalizes force on the nose and tail of each round so cartridges stack flat and feed cleanly under recoil.
4. Multi-Caliber Compatibility — Designed for 5.56/.223 and rated to run a range of AR-15 chamberings on the same lower.
5. Fits Standard AR-15 Rifles and Pistols — Drops into any mil-spec AR-15/M4 magazine well, including SBRs and pistols.
6. Reinforced Polymer Body — Impact-resistant polymer construction keeps weight down without giving up durability on the range or in the field.
7. No-Slip Grip Texture — Aggressive front and rear texturing on the lower body delivers a positive purchase during fast reloads.
8. Constant-Force Spring Design — Clock-style spring layout evens out tension from a full mag down to the last round for consistent feeding.
9. Made in the USA — U.S.-manufactured and protected by patent for the dual-spring feed mechanism.
