The ProMag MOSA1 is a 25-round detachable magazine purpose-built for the Mossberg 715T .22 LR rifle. If you shoot rimfire regularly—whether you're zeroing at the range, training with a lightweight .22, or just putting rounds downrange for the love of it—this all-steel mag extends your trigger time between reloads and takes the tedium out of frequent magazine changes. ProMag engineered it specifically for .22 LR cartridges and the 715T platform, so fit and function are dialed in from the start.
Build quality matters even in a .22 mag. The MOSA1 body is machined from heat-treated carbon steel, giving it real durability in the field or at the bench. ProMag finished the metal with a black-oxide coating to resist corrosion and wear—especially useful if you're shooting in variable conditions or storing your rig in a vehicle. The lower body is molded from polymer to keep weight reasonable and provide a comfortable grip. Inside, a heat-treated chrome-silicon spring and injection-molded follower handle the cycling, engineered to feed .22 LR reliably through a full 25-round load.
Made in the USA, this magazine is straightforward, proven, and built to work. If you're running a 715T and tired of swapping mags every eight or ten rounds, the MOSA1 gives you the capacity to focus on shooting, not logistics.
