Reliable magazines are the unsung heroes of any firearms setup. For rimfire trainers and tactical-minded shooters who value consistent feeding, lightweight handling, and domestic manufacturing, the right spare magazine can make range sessions smoother and more predictable. Whether you’re running drills, teaching new shooters, or building a dedicated practice rifle, a purpose-built magazine reduces distractions and lets you focus on fundamentals.

Shop this product to see current stock and purchase options. This review focuses on the build, handling, and field-use considerations for shooters evaluating spare magazines for their M&P15-22 platforms.
Design and Build Quality
The SMITH & WESSON M&P15-22 magazine features a one-piece molded polymer body with a textured gripping surface, a design choice that delivers a balance of durability and low weight. The polymer construction reduces the chance of dents or deformation that can plague metal magazines, while the textured surface improves purchase during quick reloads, even with gloves or cold hands.
This offering is made in USA, which matters to many shooters who prefer domestically manufactured components for quality control and supply reliability. The long model variant includes an extended housing that accommodates a 10-round capacity while maintaining a slim, ergonomic profile. Notably, this long model does not include a load assist button, a deliberate simplification that reduces moving parts and long-term maintenance points.
Why the One-Piece Molded Polymer Matters
A one-piece molded design means fewer seams and joints where dirt and debris can accumulate. For routine range work and regular dry-fire practice with a rimfire trainer, the simplified geometry makes cleaning and inspection straightforward. The textured exterior not only helps in handling but also resists slicking from sweat or oil, which is valuable during extended training sessions.
Extended Housing and Capacity
The long housing for the 10-round capacity shifts the center of gravity slightly lower and rearward compared to shorter magazines, which can be an advantage when seating the mag and maintaining balance during reload transitions. Because the design omits a load assist button, users should load carefully, using standard loading techniques to preserve spring life and maintain feeding reliability.
Performance on the Range
In practical use, the polymer feed geometry and follower work together to present rimfire cartridges consistently to the chamber. When paired with M&P15-22 rifles (Model: Various), shooters can expect predictable feeds for plinking, training, and high-volume practice. Like any magazine, a short break-in period of a few hundred rounds stabilizes spring dynamics and seating behavior.
Maintenance is simple: wipe down the exterior, inspect the feed lips for stress or deformation, and ensure the follower moves freely. Because the magazine is one-piece molded, users should not attempt internal disassembly unless they have the manufacturer’s guidance, as doing so can void warranties or damage components.
Installation and Handling Tips
Install the magazine by aligning the front lip with the mag well and rotating into place until the catch engages. Practice seating and emergency release drills to get comfortable with the textured surface and the slightly extended profile of the long model. When carrying loaded magazines for extended periods, periodically check spring tension and consider rotating magazines to maintain consistent spring life.
If you need to load quickly for drills, use a loading tool designed for rimfire mags or practice efficient thumb-loading technique. Because there is no load assist button on this long model, avoid forcing rounds in a way that bends the feed lips or stresses the spring. Treat each magazine as a precision part that benefits from careful handling.
Value, Pricing, and Fitment
At a price of $21.59, the SMITH & WESSON M&P15-22 long polymer magazine represents a cost-effective spare for dedicated range kits. For shooters using their M&P15-22 platforms for high-volume practice, having multiple magazines at this price point lets you rotate mags, reduce wear on springs, and keep sessions rolling with minimal downtime. Because the product is listed under firearms accessories for the M&P15-22, compatibility with various models in that family is intentional; check platform fit before buying if you run heavily modified receivers or aftermarket magwells.
