It covers barrel materials like 416R and 4150 CMV, various coatings (nitride, chrome-lined), rifling types, and the critical aspect of gas porting. The analysis includes specific accuracy results, barrel life expectations, and comparisons against other brands, concluding that Criterion offers a superior balance of accuracy, durability, and cost for AR-15 platforms.

Instruction from USPSA Grandmaster Mark Smith on optimizing rifle setups, emphasizing practical performance over internet trends. Key takeaways include prioritizing barrel precision over longevity for SPRs, understanding gas porting's importance, selecting robust rails to prevent POI shift, and optimizing controls and mounting for stability and ease of use. Smith advocates for gear that enhances shooter performance through intentional, data-driven choices.

This guide details the operation of the Glock 18 and 18C machine pistols, focusing on their select-fire capability. Expert Ian McCollum explains the function of the slide-mounted selector switch, which allows for both semi-automatic and full-automatic fire. The 18C's design incorporates a lightened slide and ported barrel to enhance controllability by reducing reciprocating mass and redirecting gas.

This video details modifications to the gas system cylinder of the Serbu BFG50A MKII rifle. Mark Serbu explains how to address issues with gas blow-by and piston return by modifying exhaust ports and the cylinder's end hole. The process involves CNC machining for precise port enlargement and hole sizing, aiming to optimize gas venting and piston operation.

This guide details how to tune an AR-15 for improved reliability and shooting experience, focusing on buffer systems and gas systems. It covers selecting buffer weights and springs, understanding gas system lengths, and adjusting gas blocks for optimal performance, especially when suppressed. The A5 buffer system is highlighted as a method for achieving a softer shooting rifle.

This guide details the installation and functional testing of the SureFire ProComp muzzle brake, drawing on the expertise of Ivan from Kit Badger. It covers the principles of muzzle brake operation, comparison to traditional flash hiders like the A2 Birdcage, and practical considerations for installation, including timing with a crush washer and the pin-and-weld requirement for shorter barrels. The review emphasizes the ProComp's effectiveness in reducing muzzle rise and felt recoil for a flatter shooting experience.
