High Exposure 5,664 Posted January 12, 2017 This is a pretty cool high speed video. Note the gas escaping the vent holes on the side of the bolt carrier, and coming back into the chamber from the barrel extension. 6 Quote Share this post Link to post Share on other sites
JohnnyB 4,326 Posted January 12, 2017 That is cool. Quite a bit of engineering there that I never saw in slow motion before. Quote Share this post Link to post Share on other sites

Silence Dogood 468 Posted January 12, 2017 Interesting how 'delayed' the recoil seems due to the buffer spring. Quote Share this post Link to post Share on other sites

Vlad G 345 Posted January 13, 2017 Not to mention, everything gas gases in the chamber if they are semi-auto. It is tube with two open ends and gases in it, there is only one possible outcome. Quote Share this post Link to post Share on other sites
