Going Tactical – Ep. 08: Bilateral Mount Drill

This guide explains how to accurately measure AR-15 barrel length, which is crucial for understanding its impact on muzzle velocity, terminal performance, and legal classifications. Barrel length is measured from the closed bolt face to the muzzle crown, excluding muzzle devices unless permanently attached. Understanding these measurements is key for informed AR-15 builds and legal compliance.

This guide details a comparative performance drill for the Sig Sauer MCX Rattler LT across three calibers: 5.56 NATO, 7.62x39mm, and .300 Blackout. Conducted at Take Aim Training Range by Classic Firearms experts, the drill involves speed and accuracy tests, including a 5-round transition drill at 15 yards. The 5.56 variant demonstrated the least recoil and fastest return to zero, while all calibers showed distinct terminal ballistics in ballistic gel tests.

This video from Regular Guy Training LLC features Chris and Josh discussing the pros and cons of Short Barreled Rifles (SBRs) and AR/AK pistols. They cover the financial implications of tax stamps, the practicalities of SBR use for home defense, and the technical challenges like flash and concussion. The discussion highlights the importance of proper training and equipment selection for these specialized firearms.

This guide details the GBRS Group instructors' expert-level technique for self-breaching outward opening doors in a tactical training environment. It emphasizes minimizing exposure in the 'fatal funnel' and maximizing efficiency during room entry, highlighting common mistakes and the proper coordinated approach for a two-man team.

This video demonstrates a "Pumpkin Massacre" ballistic test comparing the terminal effects of various handgun and rifle calibers. Instructors Doran and Coach from Tactical Hyve pit 5.7x28mm against 9mm Luger, 22 TCM against 5.7x28mm, and 5.56x45mm NATO against 300 Blackout, all fired from short-barreled platforms into water-filled, corked pumpkins to assess damage and mess. The results highlight differences in projectile mass, velocity, and energy transfer.

This episode of The QA features discussions on duty ammunition for SBRs, AR-15 manufacturing cost differences, red dot sight usage with iron sights, and preferred concealed carry holsters. The host, Dave, emphasizes the importance of quality control in AR-15 manufacturing and shares his experience with Speer Gold Dot 75-grain ammunition for SBRs. He also advises on red dot sight usage, noting that the target and dot become the primary focus, making front sights less critical unless the red dot fails.

This guide details the dangers of 'thumbing the hammer down' on a loaded firearm, a technique strongly advised against by experts. It emphasizes that this action, which involves pulling the trigger while manually lowering the hammer, carries a high risk of accidental discharge if the thumb slips. The expert instruction highlights safer alternatives like engaging the manual safety for 'cocked and locked' carry or clearing the chamber entirely.

This guide details the advanced technique of hand stippling a 1911 firearm frame for enhanced grip, as demonstrated by a master gunsmith. It covers the precise application of texture using a punch and hammer, followed by meticulous filing to refine the edges. This process requires significant skill and attention to detail for a professional finish.

This guide details the proper technique for cycling the slide on a semi-automatic pistol, specifically the 1911, as explained by Ken Hackathorn. It emphasizes avoiding "gun abuse" by not slamming the slide on an empty chamber, which can cause premature wear. The explanation includes the mechanical reasons behind this, focusing on how the cartridge rim stabilizes the extractor and cushions the slide's action.

Massad Ayoob, a renowned firearms instructor and legal expert, details the critical post-Defensive Gun Use (DGU) protocol. He emphasizes that the most common mistake is failing to immediately call 911 after a DGU, even if no shots were fired. This action is crucial for establishing oneself as the victim complainant in the ensuing legal aftermath.
