Finnish Recon on the Best & Worst Guns for Sub-Zero Temps (ft. Jari Laine of Varusteleka)

Published on February 19, 2025
Duration: 22:33

Jari Laine of Varusteleka discusses firearm performance in sub-zero temperatures, emphasizing maintenance over brand. Overgassed systems like the Finnish RK and piston ARs (HK416) excel due to their ability to cycle through ice and moisture. While AR-15s offer ergonomics, AKs' open systems are more prone to snow ingress. Striker-fired pistols are vulnerable if moisture freezes in the striker channel, leading to light strikes.

Quick Summary

Firearms with overgassed systems, like the Finnish RK or piston-driven ARs (HK416), perform better in extreme cold due to their energy to cycle through ice and moisture. Proper maintenance, including low-viscosity lubricants rated for -40C or -50C, is crucial for all firearms in sub-zero conditions.

Frequently Asked Questions

What makes some firearms perform better in sub-zero temperatures?

Firearms with overgassed systems, like the Finnish RK or piston-driven ARs (HK416), tend to perform better in extreme cold. They have more energy to cycle through ice and moisture. Proper maintenance, including using low-viscosity lubricants rated for -40C or -50C, is crucial for all firearms.

Which types of firearms are most vulnerable to cold weather failures?

Tight-tolerance 'race guns' are prone to failure. Striker-fired pistols are particularly vulnerable if moisture enters the striker channel, as it can freeze and cause light strikes. Open-action designs are also more susceptible to snow ingress.

What is the best handgun for cold weather according to the expert?

Jari Laine recommends any quality handgun, specifically mentioning his use of a Glock 45. The key is meticulous maintenance: keeping the firing pin channel bone-dry and free of debris that could trap moisture and freeze.

How does ice typically form on firearms in cold environments?

Ice forms primarily through condensation when moving firearms between warm vehicles and cold air. It can also form when snow melts on a hot gun and then refreezes. This ice can freeze firing pins, gas systems, or impede overall firearm function.
