Holosun 507C & 407CO Review - A threat to Trijicon and the doom of Vortex MRDS?

This comprehensive review by Regular Guy Training LLC details the performance of the Holosun 507 Comp after 35,000 rounds. The instructor highlights its robust reliability, consistent turret performance, and suitability for duty and competition. However, limitations in brightness and battery life, particularly with the circle-only reticle, are noted as potential drawbacks for some users. Despite these minor issues, the optic is deemed a solid, proven performer, especially compared to other open-emitter designs.

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 from Louisiana Firearms features Wes and Chris Boutwell discussing Staccato pistols and Trijicon optics. They highlight an upcoming 'Staccato and Trijicon Day' event on April 17th with in-store exclusive deals. The discussion delves into the differences between Series 70 and Series 80 Staccato models, focusing on trigger pull and safety features like firing pin blocks. They also compare Trijicon optic models, emphasizing the durability and performance of the RMR HD for both duty and competition use, while also touching on battery life and the evolution of red dot sights on pistols.

This video provides initial impressions of the O-SIGHT XR red dot sight, mounted on a Glock 19 Gen 5 MOS. The reviewer highlights its unique charging cap, integrated rear sight, RMR footprint compatibility, and multiple reticle options. Initial testing with 400 rounds showed no issues with the optic holding zero or coming loose.

The video argues that the Trijicon RMR is 'mid' compared to newer optics, citing significant parallax error at 25 yards. It highlights the Osite SE and Vortex Defender ST as superior alternatives with much less parallax shift, even on budget options. The speaker suggests the RMR's reputation for durability is comparable to older, less advanced vehicles.

This expert guide, drawing from an experienced instructor's review, details the installation and zeroing process for the OSIGHT SE Green MRS red dot sight. It covers essential safety precautions, screw selection, mounting, and adjustment techniques, emphasizing the optic's features like its RMSC footprint and co-witness capability.

This guide details a practical experiment to debunk the myth that an AR-15 round would 'blow off' an ear. The Humble Marksman demonstrates through testing with pig ears that common rifle rounds, and even heavier calibers, create clean holes rather than explosive damage on thin tissue. The expert's analysis highlights the difference between tissue interaction and ballistics gel cavitation.

This guide showcases the specialized 'Space Guns' used in Open Division competition at the Double Tap Championship. It highlights custom 2011 pistols, advanced optics like C-More RTS2 and Sig Sauer Romeo3 Max, and high-end holsters from Safariland and Double Alpha Academy. The content, presented by a seasoned competition shooter, offers insights into the gear and techniques employed in high-level shooting events.

This guide details an efficient iron sight technique, drawing on insights from 3-division USPSA Grand Master Tim Herron. It emphasizes a shift from rigid front sight focus to a more effective target-oriented approach, using the rear sight for gross aiming and the front sight for fine-tuning. This method is particularly beneficial for shooters transitioning from red dot sights.

This guide details the disassembly process for three popular 2011-style pistols: the Staccato P, Springfield Armory Prodigy, and Bul Armory SAS II Tac 4.25. It highlights differences in guide rod systems, with the Staccato P featuring a toolless system, the Bul Armory requiring a paperclip or staple, and the Springfield Armory Prodigy needing a hex wrench. Proper maintenance of the guide rod system is crucial for reliable firearm function.
