The QA for January 2022

This video demonstrates that fully loading a pistol magazine to its stated capacity (17 rounds for the Springfield Echelon) does not impede its ability to seat properly in the firearm. This contrasts with common practice for AR-15 magazines, where removing one or two rounds is often recommended to ensure reliable seating. The presenter uses Igman 124 grain ammunition for the demonstration.

This guide covers essential AR-15 maintenance, focusing on lubrication for firearms that haven't been used recently or ever. It details how to properly apply CLP or oil to metal-on-metal parts within the upper receiver, BCG, and charging handle, while also noting the expected presence of grease on the buffer spring and buffer. The video also addresses the common discovery of cosmoline on new, off-the-shelf AR-15s and how to remove it.

This video provides a detailed guide on proper firearm lubrication, focusing on the AR-15 platform. It emphasizes the importance of avoiding both dry firearms and over-lubrication, explaining the potential issues with each. The instructors detail specific points of lubrication on the AR-15's bolt carrier group, lower receiver, and buffer system, offering practical advice for optimal performance and longevity.

This guide provides a quick and dirty method for cleaning and lubricating an AR-15 platform rifle, suitable for new gun owners. The focus is on maintaining functionality rather than achieving a spotless finish, with an emphasis on cleaning the bolt carrier group and chamber. The presenter, an experienced firearms instructor, demonstrates a practical approach that prioritizes keeping the firearm running reliably over meticulous detailing, suggesting this method is sufficient for thousands of rounds between deep cleans.

This video showcases a novel magnetic optic mount for pistols, demonstrating its quick attachment and detachment capabilities. The speaker tests its retention by racking the slide, highlighting its potential as a firearm innovation. While initially shown on a Glock, the mount is available for other platforms like Sig Sauer and HK.

This guide covers the basic operation and features of the EOTECH OGL, a compact laser aiming device. It highlights the interface controls, including the activation button and the illuminator adjustment lever, and explains the benefit of co-aligned visible and IR lasers for simplified zeroing. The use of VCSEL technology is also noted.

This entry details the innovative Full Conceal M1 system for the Sig P320 and a prototype Folding Glock 19, both designed for enhanced concealability. The M1 system, priced at $899, integrates an 18+1 capacity with a smartphone-like footprint and active retention. The Folding Glock 19 prototype showcases a unique mechanism for rapid deployment from a compact state, utilizing a 23-round 9mm magazine. Expert insights from Chris Tran (Guns & Tactics Magazine) and Mike (Full Conceal) highlight the technical aspects and practical applications of these designs.

This guide, drawing on expert instruction from UN12 Magazine, details the critical steps for properly installing and maintaining firearm sights. It emphasizes the use of witness marks on red dot sights to ensure screw security and highlights the importance of checking iron sights for mechanical integrity to prevent zero loss. Proper installation and regular checks are vital for all sighting systems.
