Cvlife BearMight Auto-Brightness (or manual) Compact Red/Green Dot RMS RMSC RMR MOS PIC

This guide details the initial setup and range testing of a Holosun 507 Comp red dot sight on a pistol. It covers the mounting process, the importance of Loctite, and the steps for zeroing the optic. The reviewer expresses a preference for gold over green reticle colors and notes the small adjustment screws require a specific tool.

This review thoroughly tests the O-Sight XE enclosed red dot sight, focusing on its durability, performance, and features. The presenter, who has extensive experience with the previous XR model, conducts drop tests and live-fire evaluations over 3000 rounds. Key findings include its robust construction, clear optics with minimal parallax, and versatile reticle options, making it a strong contender for EDC and duty use, despite minor criticisms regarding the 'bunny ears'.

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 review covers the CVLIFE BearMight RMSc cut pistol optic, highlighting its auto-brightness feature, available in red or green dot. The optic is designed for RMSc footprint pistols but includes adapters for MOS/RMR mounts. It boasts IPX7 waterproofing, 5000 G shockproofing, and motion-awake technology, making it a versatile and durable option for concealed carry and general use.

This review covers the O-Sight XE, an RMR footprint enclosed emitter reflex sight. Key features include pop-up rear iron sights, user-selectable reticles (2 and 6 MOA dots, with circle options), a side battery tray, and IPX7 water resistance. The sight is motion-activated and offers 1 MOA per click adjustments for elevation and windage. It's presented as a budget-friendly, reliable option for pistol optics.

This video reviews two new O-site optics: the SE and the XE AMRS. The SE is a red 6 MOA dot version of a previous green model, featuring an enclosed emitter and shake-a-wake functionality. The XE AMRS offers a replaceable battery, built-in backup sights, and a multi-reticle system with 2 MOA and 6 MOA dots, optionally paired with a 32 MOA circle. Both optics are praised for their construction, enclosed emitters, and included accessories, with the reviewer expressing high satisfaction with O-site products and their lifetime warranty.

This video from Buckeye Ballistics provides a practical, albeit unconventional, comparison of five common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) by shooting watermelons. The expert demonstrates varying levels of terminal performance, from the .22LR's significant splitting to the .45 ACP's complete watermelon fragmentation, highlighting the differences in hydraulic shock and expansion. The test utilizes specific hollow-point ammunition, including Speer Gold Dot, Aguila Super Maximum, and Underwood XTP, showcasing their effects.

This video provides a practical, safety-conscious comparison of common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) against concrete blocks. The host, demonstrating high authority and expertise, details the testing methodology and results, emphasizing the risks of ricochet. None of the tested pistol calibers fully penetrated the concrete block's second wall, suggesting their limitations for certain penetration scenarios.

This review of the Taurus TX22 .22 LR pistol details its features, including a 16+1 capacity and excellent trigger. While initial testing with CCI Mini-Mags was flawless, subsequent tests with various ammunition types revealed cycling issues and culminated in a catastrophic failure. The failure was attributed to a squib load followed by a second shot, causing a barrel bulge and ruptured casing, highlighting potential ammunition inconsistencies. The review provides a detailed look at disassembly and damage assessment.

This video from Buckeye Ballistics provides an experimental comparison of three popular rimfire calibers: .22LR, .22WMR, and .17HMR, using cantaloupes as ballistic mediums. The host, an experienced shooter, demonstrates the distinct terminal ballistics of each round, highlighting how bullet construction and velocity affect target interaction. The comparison offers practical insights into the performance differences between these rimfire cartridges on soft tissue simulants.
