Smith & Wesson M&P15-22 Sport Optics Ready Review

Whether you're looking for a plinker or an AR trainer, the new Optics Ready M&P15-22 Sport from S&W has you covered.

Smith & Wesson M&P15-22 Sport Optics Ready Review
The Smith & Wesson M&P15-22 Sport with red/green dot is a blowback-operated .22 AR that ships with a dot optic mounted and ready to go.

Smith & Wesson has had great success with its M&P line of AR-15s, so it was logical for the company to expand the line into rimfires. An AR-style .22 makes an excellent as trainer, providing an inexpensive practice option where you can shoot a lot of rounds while working with the exact same controls your centerfire AR-15 or AR-10 has. And a .22 is a great plinker or small game rifle as well, of course.

The newest in the M&P15-22 family is the M&P15-22 Sport with red/green dot optic, and if you only glanced at it you’d think it was a centerfire rifle. It has a 16.5-inch carbon steel barrel tipped with a standard A2 flash hider. Surrounding this is a 10-inch M&P slim handguard with M-Lok slots and an optics rail that runs the full length and mates uninterrupted with the rail on the receiver.

The optic allows shooters to choose a four m.o.a. red or green dot and vary the intensity of the dot simply by turning the rheostat.

The receiver incorporates all the standard AR controls—including a functioning charging handle—and a brass deflector. Furniture includes a six-position adjustable stock and standard A2-style grip. The trigger is single stage, and on my sample it broke at five pounds two ounces on average. There’s a little bit of take-up but none of the grit you find on most GI triggers.

As the rifle’s name implies, this rifle comes with an optic, and it’s factory installed on an M&P mount with a single crosswise bolt with the standard 1/2-inch nut. The sight, which Smith & Wesson calls the MP-100, is pretty cool because it provides both a red and green dot. Beginning with the green Off, rotating the dot selector provides a continuously variable (no click stops) intensity on the green four m.o.a. dot until you hit the red Off. Repeat for red. I like this because it allows you not only to vary intensity but also color, meaning you can find the perfect setting for both lighting conditions and target color. It’s powered by a CR1620 battery.

The fore-end is nice and slim and features M-Lok slots for mounting accessories.

The dot is adjustable via brass windage and elevation turrets; adjustments are 1/4 m.o.a. and proved to be nicely repeatable. The turrets are capped, and the sight features flip-up caps front and rear.

Here are the accuracy results I got. They’re the averages of four five-shot groups at 50 yards from a Caldwell Fire Control rest.

Depending on where you live, the gun ships with either a 10- or 25-round magazine. The mags have orange followers, which makes it easy to see if there are rounds left.
Bullet Muzzle Std. Avg.


Weight (gr.) Velocity (fps) Dev. (fps) Group (in.)
Eley Force 42 1,164 15 1.5
CCI Standard Velocity 40 1,054 13 1.59
Lapua Midas+ 40 1,013 13 1.68

You’re not going to win any Olympic smallbore championships with this rifle, but it’s plenty accurate for training, plinking and even small game hunting at closer ranges.

I live in Colorado, which has magazine capacity limits, so the sample I received feeds from a 10-round magazine. In states without restrictions, the gun comes with a 25 round magazine. The magazine features a polymer body and orange follower. I love orange followers because it makes it so much easier to see whether there are rounds left. The bolt locks back on an empty mag, and mags fall freely when you hit the release, albeit a little slower than you might be used to with a centerfire AR.

The rifle features standard AR controls, including a functioning charging handle. That makes it a good, inexpensive training option for AR shooters.

I definitely had a fun time shooting the rifle. At five pounds one ounce with sight mounted (empty mag), there’s enough weight so it handles almost like a centerfire AR, but it’s not so heavy a young shooter couldn’t handle it. The handguard is nice and slim, and the M-Lok slots allow you to add all manner of accessories to it—lights, lasers, sling swivels, etc.

At just $469 suggested retail you get a gun that’s ready to roll right out of the box—no searching for an appropriate sight or yanking a sight off one of your current rifles.
