#GasSystem

In my last article on the K.43 I said that if I was able to get my grubby paws on an SVT-40 I’d do a comparison of the gas systems. Well, after getting extremely lucky on a GunBroker listing, I’m able to do just that.

The concept of the adjustable gas block isn’t anything really new or novel in the world of firearms. In fact, adjustable gas blocks have been used in firearms since as early as the 1930s with the Legendary M1 Garand rifle being one of the first military issue rifles to feature an adjustable gas system. Today, adjustable gas blocks are looked at as somewhat of a niche item, but one with a lot of purposes and a lot of capability when it comes to ammunition and accessory selection. Adjustable gas blocks can be beneficial in a number of ways but they usually necessitate the need for your handguard or forend to be short enough to give you access to the adjustment knob. The Riflespeed Adjustable Gas Control System essentially fixes that issue and the folks who run the company were kind enough to send me over one of their Gas Control Systems for testing and evaluation. Today we’ll go over my experiences with the product and where I think an item like this comes into play within the modern firearms world.

Good day everyone, thanks for joining us for episode #16 of TFB’s Silencer Saturday. Last week we talked about some upcoming decibel metering tests of popular suppressors along with a few of the more unique commercially available models. Since then, I have been reading up on the proper use of a meter and some standardized testing practices (no, not like the SAT). Luckily I have a few experts on standby to assist in the trials. This week I thought we should discuss gas regulation when it comes to suppressing direct impingement (DI) rifles; specifically the AR15 and its variants.

In this 201-level post on the devices and mechanisms that automatic firearms use to do their work, we’ll be discussing a distinction between two very similar types of gas systems. These are what’s commonly known as the “Ljungmann-type” gas system (called so after a Swede, even though in reality a Frenchman invented it decades earlier) and “Stoner-type” gas system. Both are forms of what’s called “direct impingement”, a term which has two different meanings, one of which we’ll discuss today

Tagged with a name that reminds me of continuously variable automobile transmissions, Newtown Firearms of Siler City, North Carolina have announced an “infinitely adjustable” gas piston operating system:
