This video covers the much misunderstood topic of bolt gap, as it relates to the Heckler and Koch roller delayed blowback line of weapons. This is a confusing topic for a lot of people.
This Video is a concise explaination and with cutaway models to facilitate learning for those unfamiliar with the system. They cover background and function, how to check bolt gap and how to affect a change in bolt gap, if needed.
Teufelshund Tactical has an extensive background as an Armorer and Instructor of Heckler and Koch weapons. Thanks for a great video!
