Why Green Dot Sights Might Not Be for Me

This review covers the Olight XR RMR-style red dot sight, highlighting its unique multi-reticle system with switchable 2 MOA and 6 MOA dots, and a 32 MOA ring. The optic features an RMR footprint, integrated backup sights, and a novel external battery pack for recharging. The reviewer demonstrates its mounting on a pistol slide, discusses its performance with astigmatism, and provides a range session showing the zeroing process.

This video provides an overview of the Holosun AEMS red dot sight, highlighting its clear lenses, multi-reticle system, solar panel backup, and shake awake feature. The presenter notes its large aiming window and suitability for handguns, suggesting it offers a significant aiming advantage. The review is presented in a casual, hobbyist tone.

This guide explains the differences between open and closed emitter red dot sights. Open emitters offer a wider field of view but are more susceptible to dirt and oils, making them better for open or duty carry. Closed emitters provide superior protection against environmental contaminants, making them ideal for concealed carry and harsh conditions. Both types are functional, but the choice depends on the intended application and user preference for maintenance.

This video demonstrates the installation of the Aimpoint CO-WA system on a Springfield Armory Echelon pistol. The presenter highlights the unique 'ski boot' and 'ski binding' mechanism of the CO-WA, which allows for secure optic mounting without screws passing through the sight itself, emphasizing a lack of side-to-side wiggle and reduced stress on screws.

This video provides a first look at the new Glock COA (Cut-Off Action) models, specifically the Glock 19 Gen 6, Glock 17, and Glock 45. It highlights the proprietary rear sight system designed to lock the COA optic in place without screws interfering with the optic's internals. The video also introduces aftermarket sight options, such as Angry Bear Sights, which offer improved co-witness capabilities and tritium inserts for low-light conditions.

This video demonstrates a durability test for the Zulisy S6-GM red dot sight mounted on a Glock 21 Gen 5. The test involves confirming zero, then physically impacting the optic on a car hood before re-testing zero. The results show the optic maintained its zero throughout the abuse, highlighting its robust construction and value. The instructor emphasizes the direct-mount advantage for Glock MOS systems.

Lucas Botkin, founder of T.Rex Arms, shares his expert insights on optimizing carbine builds based on extensive round counts. He details his philosophy on barrel length versus optic choice, preferring red dots for shorter barrels and magnification for longer ones. Botkin also discusses preferences for muzzle devices, foregrips, lights, lasers, and triggers, emphasizing reliability and simplicity for high-volume use.

This video details a critical incident during a firearms class where a custom-built pistol, featuring numerous aftermarket parts, experienced unintended discharges. The instructors meticulously troubleshoot the issue, identifying tolerance stacking and specific magazine fit as the likely culprits. They emphasize the importance of testing aftermarket components and the potential pitfalls of combining non-OEM parts.

This video discusses the practical considerations of Short Barreled Rifles (SBRs) with firearms instructor Nick Young. Key takeaways include the benefits of SBRs for suppressor use, the legal complexities involving ATF travel paperwork, and the potential reliability issues and increased violence in shorter-barreled platforms. The discussion also touches on the importance of proper buffer systems and the tendency for 'Franken-guns' to fail in training.

Hwansik Kim explains his 'No Friction Grip' technique, developed to maintain control in adverse conditions like sweaty hands or rain. The method emphasizes specific pressure points, particularly using the support hand's index finger on the trigger guard and the top knuckles of the support hand on the firing hand. This technique aims to minimize reliance on grip enhancers and provide consistent control through recoil by creating a stable platform without excessive friction.
