The Daniel Defense MK18, a compact weapon system admired for its remarkable performance in tight spaces, has established a name for itself within the tactical community. However, its exceptional nature is only fully realized when paired with an equally impressive optic. An outstanding sight not only enhances the operator’s shooting abilities but also brings out the best performance the MK18 has to offer.
Choosing an optic for your MK18 can be tricky, especially with a flooded market full of options all claiming to be the best. Therefore, we’ve dedicated this blog to offer insightful and comprehensive information on the top five optics for the MK18. We have explored, compared, and evaluated their features in detail, and we’ll recount personal experiences and the challenges faced when using these optics.
Vortex Optics Crossfire II
Product Review
The Vortex Optics Crossfire II is designed for those who don’t just value reliability and performance but consider budget a decisive factor. Vortex Optics has always been a frontrunner in providing battle-ready optics at competitive prices, and the Crossfire II emulates this standard.
Impressively, the Crossfire II offers a fast focus eyepiece that allows quick and easy reticle focusing. The fully multi-coated lenses provide clear, bright and crisp images even in low light conditions. On personal use, I found the reset turrets to be beneficial as they can be adjusted to zero after sighting in.
Challenges & Experience
The struggle I faced during the usage of this optic was the eye relief. Despite it being forgiving, finding an exact sweet spot required a little hustle.
Pros
- Affordable
- Durable
- Dependable performance
Cons
- Issues with eye relief
- Heavier than some competitors
Aimpoint PRO (Patrol Rifle Optics)
Product Review
The Aimpoint PRO is designed specifically for law enforcement and military service rifles. Unquestionably, it’s one of the market’s best optics for MK18. It’s designed to take a beating and continue delivering an exceptional performance, with a battery life that lasts for years, despite being constantly left on.
My personal experience with the Aimpoint PRO has always been positive. The excellent light transmission and negligible parallax error significantly improved my shooting precision.
Challenges & Experience
The sight is a bit bulky compared to others in its category, posing a slight challenge when aiming for extended periods.
Pros
- Exceptional battery life
- Durable and rugged construction
- 2 MOA red dot for precision
Cons
- Bulky design
- Pricey compared to some alternatives
EOTech 552 Holographic Weapon Sight
Product Review
Another optic that has proven its worth is the EOTech 552 Holographic Weapon Sight. This sight stands out for its speed and versatility, complementing the MK18’s rapid-target-acquisition capability. I was drawn to the reticle pattern with a 68 MOA ring and 1 MOA dot, which allowed quick target acquisition while maintaining accuracy.
Challenges & Experience
One minor issue I encountered whilst using the EOTech 552 was the adjustment of brightness levels. Cycling through the brightness levels seemed somewhat slow, which may affect rapid target acquisition.
Pros
- Holographic technology offers quick target acquisition
- Long battery life
- Water-resistant up to 33 feet.
Cons
- Brightness adjustment could be faster
TRIJICON ACOG 4×32
Product Review
There’s no optics review complete without a mention of the Trijicon ACOG line. The ACOG 4×32 is an optic designed for the battlefield, providing excellent target identification and hit probability. It features a dual-illumination system using fiber optics and tritium, which, during my usage, provided a consistently clear sight picture regardless of lighting conditions.
Challenges & Experience
User-friendly, the ACOG 4×32 posed no significant issues during my personal use. Its only drawback probably lies in the price tag, which may not be within everyone’s reach.
Pros
- Excellent build quality
- Great target identification
Cons
- Pricier than other optics
Primary Arms SLx Advanced Push Button Compact 1x MicroPrism
Product Review
The last optic on my preferred list is the Primary Arms SLx Advanced MicroPrism. This compact weapon sight’s standout feature is its ACSS Cyclops reticle. I appreciated the crispy sight picture, with the reticle offering diverse shooting solutions for a broad range of scenarios.
Challenges & Experience
The MicroPrism has an etched reticle, which can be a bit of a learning curve if you’re transitioning from a traditional red dot.
Pros
- Compact and lightweight
- Diverse reticle offering
Cons
- Etched reticle might require some getting used to
- Relatively new in the market
Ultimately, the optic choice largely depends on your preferences, budget, and specific use case scenarios. Regardless, these five options have proven to deliver high-quality performance, making them suitable partners for your MK18.
