Frequently Asked Questions

How did the FN SCAR 16S and Colt M4 perform in extreme cold and ice?

Both the FN SCAR 16S and Colt M4 demonstrated remarkable reliability in extreme cold and ice conditions. After being frozen for an hour, both rifles were able to fire successfully, with the M4 even continuing to function after being packed with snow.

What specific test was conducted to evaluate the rifles' performance in cold weather?

The test involved placing both the SCAR 16S and M4 in sub-freezing temperatures (below 10°F) and pouring water over their operating areas to induce freezing. After an hour, their functionality was tested by attempting to fire them.

Were there any notable malfunctions during the cold weather test?

The FN SCAR 16S experienced a failure to lock open on the last round, which the host attributed to an old magazine. The Colt M4 continued to cycle reliably even after being packed with snow.

What lessons were learned from this cold weather rifle test?

The test highlighted the importance of proper preparation, such as chambering a round before freezing to simulate a ready state. It also demonstrated that both modern platforms can perform reliably under harsh environmental conditions, though magazine function can be a factor.
