This guide details the evolution of AR-15 carrier key staking from early 'Gen 1' square staking to modern 'Gen 5' OCKS with serrated heads. It emphasizes proper torque values (vintage 35-40 in-lbs, modern 55-58 in-lbs) and the importance of sufficient metal displacement for screw security. The video, presented by an expert from School of the American Rifle, critiques commercial staking and references historical technical manuals.

This video addresses a common issue encountered when using .22 Conversion kits with AR-15 platforms, where manufacturing variances can cause compatibility problems. The "Quarter Trick" is presented as a simple and inexpensive solution to rectify these issues. The video encourages viewers to become CMMG Insiders for updates on new releases and provides links to CMMG's website, Instagram, and Twitter for more information and engagement.

This video showcases an impressive collection of firearms, rapidly displaying high-end models like the H&K SP5, KAC SR-15, and SIG Spear LT. It highlights specialized platforms such as the Genesis Arms Gen 12 PDS shotgun and the Noveske N4 in 6mm ARC. The rapid-fire montage also features a suppressed Marlin 1895 in .45-70 Government and concludes with a large caliber revolver and a Triarc OZ9.

The Gen 12 PDS shotgun demonstrated exceptional reliability by flawlessly cycling an entire magazine of the cheapest Walmart ammunition. This test, using Estate Cartridge target loads, highlights the firearm's capability to handle budget-friendly ammo without malfunctions. The video showcases rapid fire and successful target engagement, confirming the PDS's robust performance.

This video showcases the SIG MCX Spear in .308 caliber, notably equipped with an FRT trigger for rapid semi-automatic fire. The demonstration highlights the rifle's impressive performance and recoil management during high-volume shooting at an outdoor range.
