The video features a "meltdown" test of the POF P-416 machine gun, where the hosts, Eric and Iraq veteran Eddie, fire the gun continuously until it stops functioning. The test is designed to push the gun to its limits and see how many rounds it can fire before failing. The gun is fired with a variety of ammunition, including Wolf 62-grain rounds, and is tested with a combination of Magpul PMags and D60 drums.
Throughout the test, the gun experiences some stoppages and sluggishness, but continues to function despite being extremely hot and dirty. The hosts note that the gun's piston system and e-square chamber help to mitigate the effects of the extreme firing schedule.
Ultimately, the gun fires nearly 2,500 rounds before the test is concluded, with the hosts remarking that they are impressed by its reliability and durability. They note that the gun is not designed to be fired continuously in this manner, but that it has performed admirably under extreme conditions.
The video concludes with the hosts discussing the results of the test and the implications for the gun's reliability and durability. They also tease future "meltdown" tests, including one that will compare the performance of a piston-driven gun to a direct-impingement (DI) gun.
Here are the key facts extracted from the text:
1. The test was conducted with a POF P-416 machine gun.
2. The gun was fired with a 10.5-inch fluted medium profile barrel.
3. The operation is a short-stroke gas piston arrangement.
4. The barrel nut acts as a heatsink.
5. The gun features an e-square chamber system.
6. The test used Wolf 62-grain ammunition.
7. Magpul PMags were used for most of the test.
8. D60 drums were used, loaded with 250 rounds to mimic 50-round counts.
9. The test was conducted in the same order as previous videos.
10. The gun was fired until it stopped.
11. A total of 2,500 rounds of ammunition were used in the test.
12. The gun experienced some stoppages, but was still operational.
13. The gun's chamber was found to be "skanky" after the test.
14. The gun's roller cam was still smooth and operational after the test.
15. The test found that the gun's barrel wore from the throat inward and the muzzle backward.
16. The gun's rifling was still relatively strong in the middle of the barrel, but worn out at the ends.
17. The test concluded that the gun can withstand extreme conditions and still remain operational.
