[SHOT 2018] Cadex's Sheep Dog Rifle and Innovative M2 MG Mount

Miles starts by examining the Cadex M2 Cradle Mount, designed for the Browning M2. On inspection of the mount we see the zero gravity capability and the ease of use provided for manipulating the Browning M2. On top of the Browning we notice the Cadex Kolos mount integrating a recoil mitigation system and a powered ballistic reticle optic. As Miles moves to the Sheep Dog Rifle, Rob Furlong discusses the calibers offered in the new actions as well as the new chassis offered for 2018.

The Home Team Advantage: Ammunition, Compatibility, and Why Change Is Bad

If we can make a round that is significantly better than the existing 5.56mm or 7.62mm ammunition, shouldn’t the military just bite the bullet and switch, to the benefit of the servicemen and women in harm’s way? What’s stopping the powers that be from making the incremental improvements that everyone knows are possible?

Black Hawk! Omnivore holster system

Soldier Systems Daily is reporting on a new product from Black Hawk! that was introduced at Modern Day Marine, their Omnivore Holster system. Essentially the holster is designed to solve the problem of versatility that so many holster manufacturers have tried to tackle over the years. That is that usually an individual gun owner, police department, or military doesn’t own or issue out exactly one type of handgun, but has to accommodate for a variety of handguns of different sizes and dimensions over the course of several years. With each handgun comes a new holster, and often a handgun owner will have an entire bucket of holsters.

What Is a Caliber System, and How Does It Affect Ammunition Design?

In a previous post about the sometimes ambiguous meaning of the word “caliber”, we discussed how the word had mutated through the centuries, picking up different definitions and connotations along the way. In that article, I wrote:

Operating Systems 301: What Is Underlug?

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 “underslide” from a book by Brassey’s as “underlug”. More details on the error are available in the comments. Regardless, “underslide” is the proper term for this principle, not “underlug”.

Operating Systems 301: Introduction to Advanced Concepts

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 subject, so much that the advanced 301 level discussions will really only be able to scratch the surface. Before we start talking about these subjects though, be forewarned: So far I have avoided including any serious math in the 101 and 201 level posts, but we will have to tackle some math as we delve deeper into how these weapons really work.

Operating Systems Omnibus 1: Tilting, Trapping, Recoiling

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 readers, I have decided to periodically collect posts together into an omnibus post, so that you the reader can easily access and share them!

Operating Systems 101: API Blowback Operation

Previously on Operating Systems 101, we discussed the straight blowback method of firearms operation; today we’ll be talking about its close cousin, API blowback. “API” stands for advance primer ignition, which refers to the chief way that the mechanism differs from its pure cousin. We’ll get to that in a bit, but first we need to discuss the concepts of open bolt and closed bolt operation.

Operating Systems 201: Tilting Barrel Locking

Previously, we looked at the most common type of locking mechanism for rifles, but what about handguns? Well, today we’ll be looking at tilting-barrel locking, a method used in virtually every modern locked-breech handgun today.

Operating Systems 201: Rotary Locking

We introduced you to the concept of locking in a previous one of our 201-level posts on how firearms work, and today we’re going to talk about what has become the most common locking mechanism for rifles: Rotary locking. If to lock an action, you need to create an interference between the breechblock and the barrel, one of the most intuitive ways to do this is the same way a barrel bolt latch works.

Operating Systems 101: Short-Recoil

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!
