Around the end of last year (2014), Mega Arms started sending me videos of their new Slide Lock ambi-charging handle and I have to say that I just didn’t get what they were showing. From all appearances, Mega’s new Slide Lock charging handle looked, ya know Mega Cool, but seemed to function just like everyone else’s ambi-charging handle. I was wrong.
What Mega Arms is showing off in this video is an entirely new ambi-charging handle which I can only describe cryptically as “Latchless” or at least the operator does not need to depress any levers or latches to charge the AR15. What I did not see in the videos was that Mega has developed a latch which applies sufficient pressure to retain the charging handle even across all normal AR format gas pressure levels and across all the various rounds one might fire in an AR15. I am probably over simplifying a number of patents, however the “latch” is spring loaded and self-locking/un-locking.
