Matt Rittman, a 3D motion designer from Waukee, Iowa, has recently published a beautiful 3D animation demonstrating how the mechanism of a typical AK rifle works. Animations of the AK mechanism has been around for a while. Nevertheless, this one is rather well [Read More…]
The Russian PKM: Arguably the best general purpose machine gun in the world, it combines a robust reliability with best-in-class light weight. Ian McCollum of Forgotten Weapons recently released two video overviews of the weapon, giving us a good enough excuse as any to [Read More…]
The recent controversy regarding the drop safety characteristics of SIG’s P320 handgun has some taking a closer look at their handguns. Drop safety is something that – in theory – is so mature in modern handguns that it should be a non-issue, but with [Read More…]
In May of this year, I got the rare opportunity to travel to Heckler & Koch’s headquarters in Ashburn, VA, to take a look at some of the experimental and prototype firearms they have located there in their famous “Grey Room”. It wouldn’t be worth as much for [Read More…]
Note: In this article, I call this mechanical feature “underlug”. However, this is an error. Several friends of mine and I have been discussing the mechanics of firearms operation for close to a decade now, and we misremembered the term [Read More…]
In the first post of the 101 level series on firearms operating systems, we briefly described what the word cycle means in terms of the operation of automatic firearms. However, there’s a lot more to the cycle of an automatic firearm than just the completion of [Read More…]
So far we’ve looked at the most basic concepts in firearms operating mechanisms as part of the 101 series of posts, and some more advanced concepts like locking and bolt configuration in the 201 level entries. However, there is a whole lot more depth to the [Read More…]
So far in our exploration of firearms operating systems, we’ve covered ten different mechanisms for locking and actuating an automatic firearm, with two supplementary introduction posts. There’s still a lot more to talk about, but at the request of our [Read More…]
In the second of our 101-level discussions on firearms operating mechanisms, we mentioned that firearms may have what’s called a locking mechanism, which prevents the separation of the breech and barrel during the high pressure ignition of a round of ammunition. [Read More…]
Now, based on the four previous articles on gun operating mechanisms, some of my readers may be thinking “jeeze, Nathaniel, we already know all this stuff! Why are you telling us this?” Don’t worry! I haven’t forgotten about you, and that’s [Read More…]
Two basic mechanisms dominate the field of handguns today: The aforementioned straight blowback system, and short-recoil operation. The latter of two is a mechanism as clever as it is old; the first short-recoil weapons date back to the latter half of the 19th Century! [Read More…]
The first entry in our coverage of automatic weapon operating mechanisms will be the humble straight blowback method. Conceptually simple, it is one of the most common systems, being applied almost universally to .22 caliber rimfire autoloaders the world over, as well [Read More…]
What makes an automatic (or semiautomatic) weapon work? How do these weapons accomplish being able to fire round after round through a single barrel with no interference from the operator? That’s what I aim to explain in this series, which hopefully will give my [Read More…]
