The Tippmann Arms M4‑22 MMSSA Edition is a competition-focused .22 LR rifle developed in collaboration with the Metal Madness Shooting Sports Association. Based on the proven M4‑22 Pro platform, it incorporates a lightweight fluted 16" 4150 steel barrel with 1/2x28 threading & a thread protector, reducing overall weight while maintaining durability. The aluminum upper & lower receivers house mil‑spec controls including forward assist, bolt catch, charging handle, ambidextrous sling plate, shell deflector, dust cover, and adjustable flip-up sights. An MMSSA logo is laser-engraved on the lower receiver, adding a distinctive touch for competition shooters . Engineered for responsive competition use, the rifle employs a nickel-plated bolt, composite free-float handguard, and mil‑spec fire-control group. With a single-stage ~4.5 lbs trigger pull & about 5.22 lbs unloaded, it offers agile handling & crisp shooting. The adjustable stock extends overall length from 31.25" to 34.5", it ships with two magazines (available in 25, 15 or 10‑round capacities). Push-pin takedown allows fast field-stripping while remaining component-compatible with standard AR-15 upgrades .
