This video demonstrates a practical test for EOTech thermal drift. The presenter details a process of zeroing a firearm, exposing the optic to significant solar radiation, and then re-testing for point of impact changes. The experiment aims to provide unbiased data on how temperature fluctuations affect optic performance.

Quick Summary

Testing EOTech thermal drift involves zeroing your firearm, exposing the optic to extreme temperatures like direct sunlight, and then re-testing for point of impact changes. A solid AR-15 with factory loads can achieve half-MOA groupings, while vintage rifles like a 1947 Mosin-Nagant can still deliver 1 MOA accuracy.

Frequently Asked Questions

How can you test for EOTech thermal drift?

To test for EOTech thermal drift, first ensure your firearm is zeroed. Then, expose the optic to significant temperature changes, such as direct sunlight for an extended period. After exposure, fire additional shots to observe any shift in the point of impact and determine if thermal drift has occurred.

What kind of accuracy can be expected from a solid AR-15 with factory loads?

A solid AR-15 platform, even when using standard factory ammunition and not handloads, can achieve impressive accuracy. The video demonstrates a rifle capable of grouping around half an inch, indicating a well-built firearm with potential for even tighter groups with hand-loaded ammunition.

Can older firearms still achieve good accuracy compared to modern rifles?

Yes, older firearms can still achieve remarkable accuracy. A 1947 Mosin-Nagant, despite its age and original cosmoline, was tested at 100 yards and achieved approximately a 1 MOA group, proving that well-made vintage rifles can rival modern precision firearms in certain aspects.

What are the characteristics of a high-end AR-15's gas system?

High-end AR-15s typically feature hand-fitted components that contribute to a very smooth cycling action and minimal gas blowback. This results in a pleasant shooting experience, with brass often ejecting cleanly towards the 4 o'clock position without excessive gas reaching the shooter.
