A key feature is the adjustable objective (AO), which allows you to correct for parallax from as close as three yards to infinity, a major benefit for a .22 rifle often used at varying distances.

Buying Guide: Picking the Perfect Scope for Your M&P 15-22
Choosing the right optic for your Smith & Wesson M&P 15-22 is a fun part of the ownership experience. This rifle is a fantastic platform for training, plinking, and small game hunting, but its .22 LR caliber means you don’t need a scope built for a heavy-recoiling centerfire rifle. The key is matching the optic’s features to your primary use. Let’s talk about what I look for when selecting from the 10 best scopes for M&P 15-22 rifle for all applications in 2025.
First, consider magnification. For fast-paced plinking or shooting at reactive steel targets inside 50 yards, a simple red dot sight with 1x magnification is often the best tool for the job. It’s fast, easy to use with both eyes open, and perfect for honing your close-range shooting skills. If you plan on precision shooting at 50 to 100 yards, or if you’re hunting squirrels, a low-power variable optic (LPVO) in the 1-4x or 1-6x range is a great choice. It gives you the flexibility of a 1x red dot for close shots and the magnification to see small targets clearly at distance. For pure target shooting where every tiny detail matters, a fixed-power scope with higher magnification, like a 10x, could be the way to go.
Next, think about the reticle. For red dots, a simple 2 or 3 MOA dot is clean and effective. For magnified scopes, I prefer an illuminated reticle, especially for hunting in low-light conditions under a canopy. A simple duplex reticle is fine for most applications, but if you’re getting into more precise shooting, a Mil-Dot or BDC (Bullet Drop Compensator) reticle can help you hold for elevation without twisting turrets. Just make sure the BDC is calibrated for the trajectory of standard or high-velocity .22 LR rounds.
Finally, don’t forget about mounting. The M&P 15-22 has a standard Picatinny rail, so you’ll need a quality set of rings or a cantilever mount. For red dots, a lower 1/3 co-witness mount is a popular option that lets you use your iron sights through the optic if needed. For LPVOs, a cantilever mount positions the scope at the correct eye relief without needing to stretch your neck. A good mount is just as important as the scope itself; a wobbly optic is a useless one. Keep these factors in mind, and you’ll find an optic that makes your 15-22 even more enjoyable to shoot.
FAQ
What magnification scope is best for an M&P 15-22?
There’s no single “best” magnification, as it depends entirely on what you want to do. For general plinking and fast shooting at short ranges, I think a 1x red dot is perfect. For a mix of close-range speed and the ability to reach out to 100 yards for small targets, a 1-4x or 1-6x low-power variable optic (LPVO) is incredibly versatile. If your sole focus is on precision paper-punching at 50-100 yards, then a fixed 4x, 6x, or even a 3-9x scope would work well. It’s all about matching the tool to the task.
Can I use a scope designed for an AR-15 on my M&P 15-22?
Yes, you absolutely can. Any scope that mounts to a Picatinny rail will fit your M&P 15-22. The huge advantage here is that the 15-22 has almost no recoil, so you don’t need a scope built to handle the punishing shock of a .223 or .308 rifle. This opens up a world of more affordable options. A scope that might be considered budget-tier for a centerfire rifle can be a durable, lifetime optic on your .22. Just be mindful that a very heavy, high-magnification scope might feel a bit unbalanced on the lightweight 15-22.
Do I need a special mount for a scope on my M&P 15-22?
You need a mount that fits a Picatinny rail, which is the standard on top of your rifle’s receiver. For a traditional rifle scope, a set of medium-height rings will usually work fine. For a red dot sight, you can mount it directly to the rail, but many people prefer a riser or a lower 1/3 co-witness mount to get a more natural head position. For a long LPVO, a cantilever mount is the standard choice as it pushes the scope forward to the correct eye relief without you having to cram your head against the charging handle.
Is a red dot or a magnified scope better for a .22 LR rifle?
This is a classic debate, and the answer comes down to your intended use. I use a red dot when I want to shoot quickly and instinctively, like on a fun plinking day or for practicing transitions between multiple targets. It’s simple, fast, and great for training. I switch to a magnified scope when I need precision—when I’m trying to hit a tiny spinner at 75 yards or carefully aiming for a squirrel’s head. For the ultimate in versatility, a 1-6x LPVO tries to be the best of both worlds, and it does a pretty good job of it.
How much should I spend on a scope for my M&P 15-22?
One of the best things about accessorizing a .22 is that you don’t have to break the bank. While you can spend a thousand dollars on an optic, it’s far from necessary. You can find excellent red dots in the $100 to $250 range and very good magnified scopes between $150 and $400 that are perfectly suited for the 10 best scopes for M&P 15-22 rifle for all applications in 2025. The .22 LR cartridge is inherently accurate, but it doesn’t require a top-tier, shock-proof, ultra-premium scope to realize its potential. Spend what you’re comfortable with, but know that there are tons of great options that won’t cost more than the rifle itself.
