LOCALLY OWNED AND OPERATED IN IDAHO SINCE 1977
The TMAG® 20 AR/M4 GEN M3™ delivers the same proven features and reliability as the TMAG 30, but in a shorter, more compact form factor for situations where a lower profile matters. With a 20-round capacity, it’s ideal for prone shooting, bench work, compact rifle builds, and users who prefer a reduced-length magazine without sacrificing performance.
Constructed from Magpul’s proprietary Olive Drab Translucent (ODT) polymer, the TMAG 20 allows quick visual confirmation of ammunition type and remaining rounds. It has passed stringent TOP 3-2-045 military specification testing for drops, dust, and chemical exposure, ensuring dependable performance in demanding environments.
Front and rear ribbed grip panels provide positive handling, while smooth sidewalls improve visibility. Internally, the TMAG 20 uses the same optimized geometry and four-way anti-tilt follower found in GEN M3 PMAGs, delivering consistent, reliable feeding you can trust from Magpul.
