Testing of the Prototype MAX-11/15 on 02/28/17
A couple of notes:
1) Barrel is 7-1/2" long and may have contributed to some of the feed jams.
2) Upper was not lubricated at beginning of video. Performance improved after lubrication.
3) A brand new Beta Mag' was used in this video and had never been loaded or fired before. There was only one feed jam from the drum and this may have been because it was new.
4) The slow motion video was shot at 1200 frames per second. The video is grainy due to a lack of light. The day of the test was overcast and raining.
5) M4 used in video has an 11-1/2" long barrel.
