What Gas Block Size & Gas Tube Length Do I NEED?

This video explains the rationale behind choosing a mid-length gas system for an 18-inch barrel on AR-platform rifles, specifically addressing the Hansen model. It details how a mid-length system allows for a smaller gas port, more rifling to stabilize the projectile, and improved cycling balance compared to a rifle-length system on the same barrel length. The instructor emphasizes that a larger gas port is required for longer gas systems to compensate for reduced dwell time and less rifling engagement.

This video breaks down the different AR-15 gas tube lengths (Pistol, Carbine, Mid, Rifle, and Intermediate) and their impact on shooting dynamics. The presenters demonstrate how barrel length and gas system choice affect recoil, muzzle rise, and overall shooting experience, emphasizing that the 'best' system depends on the intended application and build.

This guide details the installation of a Kynshot Hydraulic Buffer (RB5000) on an AR-15 platform, as demonstrated by AT3 Tactical. The process involves disassembling the buffer system, replacing the standard buffer with the hydraulic unit, and reassembling the firearm. This modification aims to reduce felt recoil and bolt bounce, enhancing the shooting experience. The demonstration emphasizes proper firearm manipulation and function checks.

This guide details the installation of a Radian Raptor SD-SL gas busting charging handle on an AR-15 platform, specifically demonstrated on an Aero Precision M4E1 upper receiver. The process, led by an instructor with high authority, involves basic disassembly, installation of the specialized charging handle designed for suppressed fire, and reassembly. The video highlights the ambidextrous features and ported shaft for gas redirection.

This guide details the installation of the Armaspec Stealth Recoil Spring (SRS) on an AR-15 platform, as demonstrated by AT3 Tactical. The video highlights the audible difference between a standard buffer spring and the SRS, emphasizing reduced felt recoil and elimination of spring noise. The process involves a simple field strip and component swap, making it an accessible modification for AR-15 owners seeking a smoother shooting experience.

This guide details the installation of a Sprinco buffer spring into an AR-15 platform rifle, specifically demonstrated on a Springfield Armory Saint. The process involves removing the old spring and buffer, installing the new Sprinco spring, and reassembling the buffer tube. The video highlights the potential for a smoother and quieter action with this aftermarket upgrade.
