Optic Cuts - Direct Milling vs MOS

This guide details the installation of an Aimpoint COA red dot sight onto a Glock 19 pistol slide that has been milled for an optic. The process involves ensuring the firearm is safe, removing the rear sight, aligning the optic, and securing it with the provided hardware. The video, presented by GlockStore, demonstrates the unboxing and mounting procedure, highlighting the precision required for optic cuts.

This video from American Rifleman features Mitchell from Langdon Tactical discussing customization options for the CZ P-09 pistol. Langdon Tactical focuses on enhancing fundamentally excellent firearms, particularly addressing the P-09's trigger pull. They offer two trigger job levels: Level 1 smooths factory parts and changes springs, while Level 2 replaces internals with Cajun Gun Works components for a lighter pull (5.5-6 lbs) and reduced reset. Additionally, they can modify the factory RMSC optic cut to accommodate larger optics like the Delta Point Pro, making the P-09 a more versatile carry option.

This guide details the process of mounting an optic onto the Glock 17L Gen 5 MOS, drawing from expert insights provided by Lenny Magill. It covers the use of the Modular Optic System (MOS) and highlights considerations for different optic models like the Holosun 507 Competition and SCS, including potential co-witness issues with standard plates.

This guide covers the installation of aftermarket custom Glock slides, drawing on insights from Tactical Toolbox. It emphasizes checking compatibility, installing necessary components like channel liners, and performing function checks. The video highlights various brands like Brownells, L2D Combat, Norso CNC, Polymer80, and Legion Precision, noting their unique features and finishes. Proper installation ensures enhanced firearm performance and aesthetics.

This guide details the process of having a Glock slide milled for a red dot optic, a modification popularized by GlockStore. It emphasizes the benefits of milling over dovetail mounts for a lower optic profile and the importance of co-witnessing with suppressor-height sights. The process involves sending the slide to GlockStore, where CNC milling ensures a precise fit for popular optics like the Trijicon RMR.

This video details how to upgrade an HK USP pistol for improved performance and modern capabilities, focusing on professional gunsmithing services like those offered by Langden Tactical. Key upgrades include a refined trigger system for a shorter reset and smoother pull, an optic cut for red dot sights, and the addition of weapon lights via specialized adapters. The presenter emphasizes that while factory reliability is high, professional upgrades can enhance functionality without compromising dependability, especially for SHTF scenarios.

This video from TREX ARMORY, featuring Lucas Botkin, critiques the trend of over-accessorizing firearms, particularly the Sig Sauer MCX. It highlights how excessive attachments can lead to impractical setups, especially for users who engage in high-volume training. The discussion focuses on the heat transfer issues associated with aluminum foregrips and the potential redundancy of certain mounting solutions.

This video from TREX ARMS focuses on maximizing value when purchasing an AR-15, emphasizing performance per dollar spent over simply choosing the cheapest option. Instructor Brandon highlights key components like upper receivers, lower parts kits, triggers, and optics, recommending specific brands and configurations that offer the best balance of cost and capability. The discussion covers different AR-15 roles (CQBR, SPR, GPR) and illustrates the concept of diminishing returns in firearm component upgrades.

This guide details the assembly of a budget-friendly AR-15 rifle, focusing on cost-effective component selection without compromising core functionality. The build prioritizes investment in critical parts like the barrel and BCG while saving on furniture and lower receivers. It highlights performance data, including accuracy with various ammunition types and the impact of heat on sustained fire accuracy.

This video provides a critical review of a $220 Chinese clone of the Vortex Razor 1-6 HD II. Lucas Botkin, an established firearms industry influencer, details the clone's significant performance shortcomings, including poor illumination, turret wobble, point-of-impact shift, and failure to hold zero under recoil. The review emphasizes that the clone is a poor value compared to the genuine article or even quality red dot sights.
