Vortex Optics Strikefire II Red Dot Sight — best scope for Smith and Wesson M&P 15 Sport 2

Vortex Optics Strikefire II Red Dot Sight — best scope for Smith and Wesson M&P 15 Sport 2

The Vortex Optics Strikefire II is a versatile sight that will nicely complement your M&P 15 Sport 2. You can choose between a red or a green dot and 10 brightness levels, so you never miss your shot.

Vortex Optics is arguably one of the better-known optics manufacturers. This fame is not without reason — time and time again the people at Vortex have proven that they know how to make excellent (and affordable) sights.

The Strikefire II is no exception. This red dot sight is accurate and has a few tricks up its sleeve. It isn’t exactly the most technologically-advanced sight, and it is not packed with features, however, what it does, it does well — and without breaking the bank.

The sight itself is made from an aluminum alloy, which makes it resistant and lightweight. The Strikefire II is sturdy while weighing a mere 7 ounces. This compact and solid build also makes this sight a resistant piece of equipment — besides being able to withstand most impacts, the Strikefire II can operate from -22 to 140ºF and is completely waterproof.

The most interesting feature of the Strikefire II is the ability of choosing between a red and a green dot. This is more than a simply aesthetical choice — our eyes are more sensitive to green light. The green dot is easier to see during the day, and you can use a lower brightness level than with the red dot.

Speaking of brightness levels, the Strikefire II has 10 brightness levels for both the green and the red colors. The highest level is very, very bright — which is useful during sunny days. Regardless of the weather and light conditions, you will always be able to see the reticle.
The two lower brightness levels are compatible with night-vision, further making the Strikefire II a very interesting purchase.

This reticle can be used with both eyes open, and your position does not matter when it comes to accuracy. If you can see the reticle, then you will most likely hit your shot.

Both elevation and windage can be adjusted via the corresponding dials, which can be accessed by removing the dial cover. Unfortunately, you cannot adjust the dials without any tools — but a coin or the dial covers themselves will do the trick.

Once you consider the price of the Vortex Optics Strikefire II, you will probably come to the same conclusion I have: this is an excellent red dot sight for any rifle. It is not the best sight you could theoretically purchase, but it excels at its job, especially given its price.
If you are looking for a great sight for your Smith and Wesson M&P[1] 15 Sport 2, then you will not be disappointed with the Vortex Optics Strikefire II.

Can you clearly see the green/red dot?

Yes. The Vortex Optics Strikefire II not only lets you choose between the color of the dot, but it also lets you control its brightness. There are 10 brightness levels — you will always be able to see the dot.

In cases where it is completely dark and you are using the highest brightness settings, the dot might fragment itself and appear blotched. To counteract this, simply dial the brightness back.

Users with astigmatism might have some problems clearly seeing the dot. Astigmatism makes the dot to appear mishappen and gives it a starburst-like effect — however, this will happen with every red dot sight. Still, depending on your astigmatism severity, it might still be completely possible to use the Strikefire II or any other red dot sight.

How long will a battery last?

The expected battery life will vary depending on the brand of battery you use and the settings on your Strikefire II. Assuming you aren’t using a knock-off, cheap CR2 battery, the battery should last you 300 to 400 hours at max brightness levels.

If you dial the brightness all the way back to the minimum levels, the battery can last up to 7,000 hours.

To prevent unnecessary battery usage, the Strikefire II will automatically turn off after 12 hours. So, even if you forget to turn off the red dot, you will waste, at most, 12 hours of battery life.

What type of co-witness will I get with this sight?

The Vortex Optics Strikefire II 1/3rd co-witnesses with the iron sights of the Smith and Wesson M&P 15.

Vortex Optics Sparc II Red Dot Sight - 2 MOA Dot — best red dot for S&W M&P 15 Sport

The Vortex Optics Sparc II is a simple, high-performance red dot sight. If you are looking for a no-frills red dot sight, then the Sparc II might just be right up your alley.

When I said that Vortex[2] Optics was well-known for a reason, I meant it. The proof is the fact that I felt the need to also consider another of their products, the Vortex Optics Sparc II, as one of the best scopes for the MP 15 Sport 2.

Comparing the Sparc II with the Strikefire II is inevitable. Optically, these two scopes are almost identical (I felt the Strikefire II to be slightly better), but the Sparc II does almost everything as well as its bigger brother — for a relatively cheaper price.

Of course, the cheaper price tag also means that some features are missing — most notably the ability to choose between a green or a red dot. The Sparc II exclusively uses a red reticle, but it still has 10 brightness levels.

The red reticle gets as bright as the red reticle on the Strikefire II. A green reticle is always going to be brighter, but the brightness on the red dot does not disappoint.

Construction-wise, the two scopes are very similar. However, the build on the Sparc II is slightly worse — this is not to say that it is a bad scope. The Strikefire II simply feels like a more premium product. The Sparc II is made from aircraft-grade aluminum and weighs a bit over 6 ounces.

There is no parallax on the Sparc II, and eye relief is unlimited. Despite the fact of this scope not being quite as good as the Strikefire II, there is one thing that it does better than the more premium scope: windage and elevation adjustments. Unlike the Strikefire II, both adjustment knobs on the Sparc II can be used without the aid of any tools.

Brightness can be controlled via the two buttons on the side. The buttons feel a bit mushy, bit I found that to be a little bit irrelevant — rarely, if ever, you fiddle with the brightness after you’ve set it for the current light conditions.

One great thing about this scope is the fact that Vortex packs it along with its modular base. Like with the Strikefire II, you can mount the Sparc II at your preferred height.

If you can spare the few extra dollars, I’d advise you to go for the Strikefire II. If you are on a strict budget, then by all means go for the Sparc II. This is definitely one of the best red dot sights for the MP 15 Sport 2.

Is there an included riser mount?

Yes. Vortex includes everything you need to mount the Sparc II exactly as you want it. The Sparc II comes with a riser mount, a spacer, and a low mount.

This red dot sight also comes with flip-up dust covers.

Can you use this sight to co-witness?

Yes. Thanks to the included mounts, you can use the Vortex Optics Sparc II to 1/3rd or fully co-witness with the iron sights of your M&P 15 Sport 2.

Will this mount fit a standard Picatinny rail?

Yes. This red dot sight will fit most picatinny rails.

Bushnell Optics TRS-25 Hirise 1x25mm

Bushnell Optics TRS-25 Hirise 1x25mm

The Bushnell Optics TRS-25 is a great red dot sight for the shooter on a limited budget. While lacking some features of the most expensive scopes, this is a sturdy red dot excellent for inexperienced shooters.

View on OpticsPlanet View on Amazon

The Bushnell[3] Optics TRS-25 is not a red dot that I would recommend to everyone. This is a relatively inexpensive red dot sight that better suits inexperienced shooters than the hardened professionals, who will definitely find it lacking in several aspects.

First and foremost, you should be warned that this scope does not come with an included riser mount. Most times, this is not a problem. However, you will definitely need a riser to be able to clear most rifles — for the S&W M&P 15 Sport 2 you will need one as well. Although risers are not that expensive, you should still factor in the extra cost.

The scope itself is fine. It will not amaze you with its quality, but it definitely does not feel like a toy either. As you would expect from any respectable manufacturer, the TRS-25 is O-ring sealed, making it waterproof.

This 3-degree MOA scope is easy to zero, and you should have no problems with the adjustment screws. The glass is acceptable, and you should be able to see clearly through it in most conditions.

The red dot reticle is a standard red dot, with no extra tricks up its sleeve. There are 11 brightness levels and it’s easy to see the reticle with the brightness all the way turned up.

If so far the Bushnell TRS-25 does not seem like an entry-level scope, you will be sad to know that it very much is — and that is because of its durability. The Bushnell TRS-25 seems to be unable to handle recoil over time. After a few years (maybe even months) the glass will fall apart.

For the time you are able to use it, the Bushnell TRS-25 is a very respectable entry-level scope. However,r the fact that it will eventually break apart makes recommending it hard. You should only get this scope if you are a beginner and don’t intend on using it very often.

Does Bushnell include a mount riser?

There is no mount riser included, which is very unfortunate. To use this scope with the MP 15 Sport 2 you ideally would want an 0.8-inch riser, which must be bought separately.

How bad is the starburst effect on the TRS-25?

Unless you have astigmatism, there is no considerable starburst effect on this reticle. At the highest brightness level there is a slight bloom, but that is to be expected due to the brightness intensity.

How long will a battery last?

Bushnell claims that a single battery will last for up to 3,000 hours. The manufacturer doesn’t specify the brightness level for this rating.
As with most red dot sights, battery should last you more than enough time. Nevertheless, it never hurts to have a spare battery nearby.

UTG 3X Magnifier with Flip-to-side QD Mount

UTG 3X Magnifier with Flip-to-side QD Mount

The UTG 3X Magnifier is a versatile magnifier that can be of help in those moments that you feel that your red dot does not give you enough range.

View on OpticsPlanet View on Amazon

First, let’s make one thing perfectly clear: the UTG 3X Magnifier is not exactly a scope — this is a magnifier for your scope. As you probably know, red dot sights are not intended for long range uses; they excel in close quarters and, at the most, medium distances. With a magnifier, things are a bit different.

While it will not exactly give you the reach of a long-range scope, a magnifier can be helpful if your targets are further than you’d wish. Magnifiers increase the magnification and the field of view, making it easier to see through your red dot sight.

The UTG magnifier is a cheap add-on to your Picatinny-railed rifle that will probably not impress you. However, if you do find yourself needing the extra range, you will be thankful for its existence.

The fact that this is such a cheap product, means that its materials aren’t exactly great. The aluminum exterior feels cheap, and the glass leaves a lot to be desired. However, it gets the job done — and for the price you can’t really complain.

The flip-to-side QD mount makes it easy to use the magnifier. Just flip it up to use it and flip it back down to remove it from your rail. While you cannot change the magnification level (it is strictly 3x), you can adjust the windage and the elevation, so it perfectly fits your sight.

But this is the part where things get trickier. The UTG magnifier does not co-witness with a large number of sights due to its basically non-existent eye relief. You need to put your eyes close to the eye piece to be able to focus, which isn’t exactly doable on a rifle — not unless you want the recoil to hit you in the face.

The alternative to this is to put the magnifier as far back on the rail as you can, however this will not only make it impossible to co-witness with most sights, but it will also make it very difficult to clear the rifle’s iron sights.

When it works, the magnifier does a great job considering its price. However, don’t forget to do your due diligence before you buy it — there’s nothing worse than buying an useless product.

Will this magnifier work with the Vortex Optics Striker II?

The Striker II is 40mm tall, while this UTG magnifier sits at 42mm. While it can work without any modifications, it is recommended that you use a riser.

The same goes for the Sparc II. Both these optics sit too for optimal use with this magnifier, but you can find a workaround.

Is this magnifier strictly right-side flip?

Unfortunately, yes. If you want a left-side magnifier you will have to find another product. When installed correctly, the UTG 3X magnifier is only right-side flip.

EOTECH XPS2 Holographic Weapon Sight

EOTECH XPS2 Holographic Weapon Sight

The EOTECH XPS2 is one of the best holographic sights you can buy for the Smith & Wesson M&P 15 Sport 2. This holographic sight has a green reticle and 20 brightness levels, so you can adjust it to every situation.

View on OpticsPlanet View on Amazon

When it comes to red dot sights, it is very difficult to beat holographic sights. And once you are in the holographic territory, EOTECH stands out.

The XPS2 is a super lightweight holographic sight that will fit in the shortest of rails. If you want to save up some rail space, then this is probably the right sight for you.

But don’t let the fact that the XPS2 is small and compact convince you — let the 20 brightness levels of this green reticle do it instead. You see, it is basically impossible not to see the reticle, regardless of the weather condition.

Not only that, but the reticle will still continue working even if the sight windows gets shattered or obstructed by debris, such as snow or mud. You might need to zero the sight again, but other than that it will continue functioning.

The greet reticle features a 68 MOA ring and a 1 MOA green dot. This holographic sight is also available in versions with red elements, both with and without the outer circle. However, green-colored reticles can be up to 6 times easier to see than standard red ones.

This is a great holographic sight — but it has a price to match. While it is very easy to recommend, you have to ask yourself the question: will my use justify the price tag? If it does, then don’t think twice — you’re getting plenty of scope for the price.
