Owners of the M&P15-22 Sport frequently cite it as a low-cost way to practice AR manual-of-arms without burning through centerfire ammunition. The controls mirror a standard AR-15 closely enough that the transition between the two rifles feels natural, and most owners find the 25-round magazine capacity satisfying for range sessions.

The trigger on the M&P15-22 Sport gets mixed reviews. Some owners find it acceptable for rimfire plinking, while others describe it as mushy compared to dedicated rimfire target rifles. Feeding reliability is generally good with quality high-velocity .22 LR, but some users report sensitivity to bulk-pack ammunition.

At its price point, the M&P15-22 Sport competes well on build quality. The black polymer stock feels durable rather than premium, and the flat top rail accepts standard AR accessories. Common upgrades include aftermarket triggers and upgraded pistol grips, reflecting an active accessory market for the platform.
