Most automatic weapons, with the exception of really weird designs like the Madsen LMG and Hino-Komuro, have a linear reciprocating breech member; either the bolt or a bolt carrier group. This reciprocating member is supposed to move rearward (the recoil stroke) and pull the spent case from the chamber, and then rebound off of a spring to shove a new round into the chamber (the counter-recoil stroke). After the counter-recoil stroke the reciprocating mass should come to a halt in its forward-most position; the "in-battery" position. When the bolt carrier group is in battery the case is enti
At the end of January, 2018 and after many false starts, the Russian military formally announced the limited adoption of the AEK-971 and AEK-973 rifles. These rifles feature an unusual counterbalanced breech mechanism which is intended to improve handling, especially during full auto fire. While exotic outside of Russia, these counter-balanced rifles are not at all new. In fact, the 2018 adoption of the AEK-971 represents the first success of a rifle concept that has been around for a some time.

It is time to explain The Aglockalypse. This is the handgun that killed handgun design in the West. Nobody has had any new ideas worth mentioning on the mechanical design of service handguns since this design came out. Almost every major arms manufacturer in the West makes what is materially a Glock clone; albeit with a few small embellishments and their own logo stamped on the side. What Makes a Glock a Glock? Almost every mechanical contrivance in small arms design was invented about one hundred years ago by some Austro-Hungarian noble you've never heard of or by John Moses B
