Even the best gun is useless if you miss. A simple red dot sight can provide a significant boost to performance, even on guns like the AR-15 that already perform well. Naturally, there are quite a few options to choose from, so we decided to help with the search by finding ten contenders for being the best red dot for AR 15. Our rankings focus primarily on value, overall performance, and durability to make sure that all of these red dots can perform to a high standard in the field without any problems.
10. Eotech 512
The 512 is a holographic sight intended for use by law enforcement as much as by civilians. Their rectangular shape is a little bit unusual, but it does ensure that they offer an acceptable wide field of view to the user. That’s useful for hunters who want to watch a large area for their prey, and the unit’s water resistance also makes it good for wilderness use. Experts with a big budget might consider this expensive tool as a contender for the best red dot for AR 15.
9. Holosun HS403B
The HS403B the best red dot for AR 15 for users that want long battery life. It relies on a simple LED to produce a 2 MOA dot, which is sufficient for most uses. The battery should last 50,000 hours on a moderate setting, so it’s great for anyone who tends to forget to turn the light off before putting their gun away. People who aren’t concerned with getting the longest possible battery life should consider other options.
8. C-MORE Systems Railway Red Dot Sight
There are several variants of the Railway system, some of which are designed specifically for the AR-15, while others are simply compatible with it. Quick target acquisition is its best feature, so it’s a decent choice for competitive shooters, but the real gem is the size of the dot. There are several options, but the strongest of them is an impressive 16 MOA. The body is sturdy aluminum, so this model is sturdy enough for use by hunters, but it really shines for competitive shooters, especially the experts who know how to get the most out of each setting.
7. Aimpoint Micro H-1
The Micro H-1 is a tiny red dot system intended for hunters. It’s fully waterproof, offers twelve illumination settings and it can be adjusted for windage without any special tools, so it’s very easy to use it in the field under any conditions. The mount helps with absorbing recoil, so it’s easy to take multiple shots quickly if the first one misses. It’s a little bit on the expensive side, which stops it from getting the top position, but it’s one of the best red dot scope for AR-15 for experienced hunters.
6. Sightmark Ultra Dual Shot Pro
The Sightmark Ultra Dual Shot is a versatile sight that offers two firing options. The first is a side-mounted laser for quick shots, either in dangerous conditions or in competitions. The second is a dual-pane glass system for slower shots. It is also designed to be used in tandem with a night vision monocular. That allows novice shooters to start with this site, and add in a night vision system when they’re ready to upgrade. That’s the best use for this sight, although it also has value to experienced shooters who can use its versatility.
5. Trijicon MRO
The MRO is one of the newest designs out there, and it offers an excellent blend of features. The housing is made of waterproof, aircraft-grade aluminum, so it can hold up to most uses. The glass is also clearer than most of the alternatives at this price range. The controls are ambidextrous and easy to reach, which makes this one of the most convenient systems to adjust during use. Those features make this a great option for general use by new and intermediate shooters. However, it lacks the specialized features that make other options better for specific roles so this might not be the best red dot for AR 15 out there.
4. Tasco ProPoint
The ProPoint is the best red dot for AR 15 novices on a budget. It attaches very easily to most weapons, and adjusting it for windage is similarly simple. Adjusting the brightness is necessary under some lighting conditions to prevent the dot from getting too bright to use, but that adjustment is easy enough to ensure that isn’t a problem. The magnification is lacking, so it’s most effective at close range. However, it’s a reasonably good choice under those conditions. Pick this if you’re a novice who wants something cheap. Look for a more elaborate sight if you’re willing to spend more.
3. AT3 RD-50
The RD-50 is a budget choice specifically for the AR-15. It has a parallax-free design and it is convenient for new shooters that aren’t used to dealing with red dot systems. It’s also remarkably dependable, with a tough aluminum case that resists water and a long battery life. The battery is rated for 50,000 hours, but only on the lowest setting. Thus most people won’t get quite that much use out of it. Choose this red dot system if you’re a beginner who wants something cheap and simple, or an expert who doesn’t want to spend too much to get a good system.
2. Vortex Sparc
The Sparc is the best red dot for AR 15 users in need of something tough. The tough rubber house makes it take much more of a beating than most other red dot systems. It also only needs a single battery, so you only need a single spare battery when you take it out into the field. The optical performance is good, but not exceptional. You should pick this system if your primary concern is something that can survive fairly rough treatment without breaking down.
1. Bushnell TRS-25
The TRS-25 is relatively cheap, but it offers a lot of performance. It resists water, fog, and shocks, so it’s sturdy enough to use in almost any environment and cheap enough to replace if it does break. Because of its eleven different brightness settings, you can use this gun in almost any light conditions. It is the best red dot sight for the money, especially for novices or anyone who expects to use it roughly. It does offer enough performance to remain valuable to more experienced shooters who would rather not pay for an upgrade.
