Mud Test of M1A, MAS 49/56, and AR15

About a 9 minute video at InRange TV. For those without the time or means of watching the video, the gist is that they take three rifles--the M1A, the MAS 49/56, and an AR15--and crawl through a mud-puddle, making sure to get the firearms thoroughly coated in mud, and then test fire. The first weapon up was the MAS 49/56, an autoloading rifle used by the French through much of the Cold War period. It performed pretty well, having a couple problems toward the end of its feed. The M1A was able to get 2 shots off before completely freezing up--it was a complete failure. The AR 15 did the best, firing 18 out of 20 rounds.
