What to Consider When Choosing a Picatinny Rail

Choosing the right Picatinny rail is crucial to getting the best out of your optics. Various criteria determine which rail best suits your requirements. Below are the most important aspects to consider.

Material and Durability

The material of the rail plays a significant role. Aluminum rails are lightweight and cost-effective but less robust. Steel rails, on the other hand, can withstand more intense use but are heavier and more expensive. Polymer rails are less commonly used and are usually intended for specific applications.

Weight and Profile Height

The weight and profile height of the rail are particularly important if you want to use night vision or thermal optics. Lightweight rails improve portability, while a low profile allows for a comfortable cheek weld. This is especially relevant as modern thermal optics often come with significant weight. For example, the Trijicon IR-HUNTER MK3 60MM weighs about 1,072 g, while the ATN ThOR 5 LRF weighs around 873 g.

"The Fast Mini is a tiny thermal optic just about the size of a red dot. With its size and versatility, you can use it as an optic on a pistol, a standalone optic on a rifle/PCC, or mount it on the side of your rifle with another optic to use as a scanning device. (Or as a mini thermal scope because why not)." – Texas Plinking

Compatibility

Another key factor is compatibility. Ensure that you are using a genuine Picatinny rail that meets MIL-STD-1913 specifications. Not all rails that look like Picatinny rails meet these standards. Also, check if the rail fits your weapon – a compatibility chart can be helpful here.

Weaver rails are often not compatible, as their slot dimensions deviate from MIL-STD-1913 specifications. However, since 2012, the firearms industry has largely standardized on Picatinny rails to ensure universal compatibility for tactical accessories.

Mounting System Type and Preparation

The type of mounting system can significantly influence your usage options. Fixed mounts provide maximum stability, while detachable systems offer more flexibility, e.g., for switching between day and night optics.

Proper preparation of the mounting surface is crucial for a stable attachment. Clean the surface thoroughly, initially attach the accessory by hand, and then tighten it with appropriate tools. For optimal results, specially designed mounting systems should be used.

Mounting Night Vision and Thermal Optics on Picatinny Rails

The mounting of night vision and thermal optics requires precision, as these devices have different requirements than conventional scopes. Correct mounting is crucial for accurate shots and optimal use.

Adjusting Eye Relief Correctly

Eye relief plays a vital role in achieving a clear view through the optic. According to Warne Scope Mounts, eye relief is “the distance between the ocular lens of a scope and the shooter's eye that allows for a full field of view without vignetting, blackouts, or other visual disturbances.”

“Consistency means accuracy and speed, which is important for hunting, target shooting, and competition.” – Warne Scope Mounts

The optic should be mounted in such a way that the field of view remains complete without requiring unnatural head movement. Your equipment, such as a helmet or safety glasses, can also affect eye relief and should be considered during mounting.

Challenges with Repeating Rifles

Mounting thermal optics on repeating rifles often presents unique challenges. The bolt handle can restrict space for the optic, and the ideal eye relief is often harder to adjust.

A possible solution is extenders like the LaRue LT101, which brings the optic into the optimal position. Alternatively, the Picatinny rail can be mounted backward to shift the optic further back.

Weight Distribution and Ergonomics

Heavy optics can significantly affect the balance of your weapon. If the optic is mounted too high, stock attachments or adjustable combs can help improve ergonomics. A stock with a shorter length can also optimize comfort and handling.

Be careful not to tighten the mounting rings too much, as excessive torque can deform the optic body and impair precision. Use a torque wrench and adhere to the manufacturer's specifications.

Legal Regulations in Germany

In addition to the technical aspects, there are clear legal regulations in Germany regarding the use of night vision and thermal optics. The purchase and sale of night vision attachments and thermal monoculars are generally exempt from approval.

Important Restrictions:

• Night vision attachments and aiming devices with electronic image converters may not be mounted on firearms.
• Illumination devices or aiming markers on firearms are prohibited.
• In some federal states, the use of night vision and thermal attachments for hunting is prohibited.

However, for hunters with a hunting license, there are exceptions: The possession and use of night vision attachments for hunting purposes have been eased, although this regulation may not yet be implemented in all federal states.

Practical Tips for Mounting

Adjust the illumination of the reticle to the respective environment to avoid glare or overexposure. During longer observations, regular breaks help relieve the eyes.

For flexible use on various weapon systems, Picatinny mount extenders are a good choice. These work on both AR platforms and repeating rifles. Be sure to choose a robust model to avoid flexing or shifting.
