What is the RIFLESPEED - Gas Control 4.3" Model RS6243 0.625" Diameter?

The revolutionary RIFLESPEED™ Gas Control System (US Patent #US20200116446A1, additional patents issued and pending) makes controlling your rifle's gas flow reliable, repeatable, and foolproof. Need more gas? Turn it up. Need less gas? Turn it down. With the easy-to-grasp Control Knob, it's that simple and no tools are required. The highly visible numbering on the Control Knob ensures that you'll always know your setting. Return to a previous setting instantly by simply turning the Control Knob. Each setting is indicated by a highly tactile ""click"" for use during times of reduced visibility. Two separate rotation ranges with numbered settings 1-12 and multiple Plunger sizes cover the adjustment requirements for every available cartridge. The patented Rotation Stop feature prevents unintentional disassembly. Uses RIFLESPEED straight gas tubes Designed for the most rigorous Military or LE Duty Use, RIFLESPEED Gas Controls are also ideal for defensive use, competition, recreational shooting, or hunting. RIFLESPEED Gas Controls are durable and proven to perform through tens of thousands of rounds of ammunition spent in developmental and destructive testing. Gas Controls from RIFLESPEED are the ultimate solution to the problems of operating hard-use carbines in varying conditions, configurations, and environments. With complete control of the gas that's delivered to the action of your rifle with each shot you'll enjoy increased reliability, reduced recoil, reduced muzzle rise, less aiming disruption, less wear and tear on your rifle, and improved accuracy. Set your RIFLESPEED Gas Control for ideal performance with light commercial ammo or higher-pressure milspec ammo. Dial your gas system in for ideal performance in extreme heat or frigid cold conditions. Enjoy optimal performance with or without a suppressor. With a properly adjusted gas system you can eliminate the need to use exceedingly heavy buffers. Once you experience the advantages of using a RIFLESPEED Gas Control, you’ll never want to shoot anything else.

Rifle Speed
The rifle speed adjustable gas block is the best way to tune your SBR suppress or not hands down. Pricey but worth it.

They got this right
I am very pleased with this purchase… I used the rifle speed adjustable gas block to enhance my Ruger SFAR. I went with the Midwest 14” G4 hand guard and the 5.8” gas block… the fit was very nice and the adjustability made the gun shoot like it should with the wide range of ammo that is available for a 308 rifle. I have actually already reordered this for another rifle as it works so well and will become the standard on my DI rifles that I run suppressed.

So much better
SO much better than the set screw types I've used in the past. Beautifully made and installs very easily.

#1 for Suppressors
At first when I saw the price I almost spit out my drink because of this price Others are lower and have all 3 versions with all the sizes It would be in your best interest to at least have one version one one of your suppressed guns or even a gun you are taking super long shots with when your ammo isn't in a climate controlled box In most Vetran shioters minds this version is the best because it takes the least maintenance Control the night and with this from far away
