Performance Review

This video showcases advanced tactical training from GBRS Group, covering a spectrum of skills from fundamental pistol marksmanship to complex CQB, night vision operations, and vehicle interdiction. The instruction emphasizes responsibility and proficiency in various environments, including indoor ranges, outdoor training areas, and simulated urban settings. Expert instructors guide participants through dynamic drills, highlighting the importance of teamwork, weapon system mastery, and tactical decision-making.

This video demonstrates a practical, albeit informal, test of bullet penetration through common building bricks using various firearms and calibers. From .22 LR to .50 BMG, the experiment visually showcases the significant differences in ballistic energy and stopping power. The presenter, Parker, offers an enthusiastic and knowledgeable approach, highlighting the destructive potential of each round.

This video provides expert guidance on stockpiling ammunition, emphasizing pattern recognition of market shortages rather than panic buying. It details seven calibers that consistently become scarce, offering specific recommendations for reserve quantities for each, distinguishing between training and defensive loads. The advice is presented from the perspective of a firearms instructor focused on practical preparedness.

This video from Line45, hosted by Ted, outlines seven critical ammunition calibers Americans should stockpile to prepare for potential ammo shortages, referencing patterns seen in 2020 and anticipating a 2026 crunch. Ted emphasizes the importance of having sufficient defensive and training ammunition for various firearms, detailing why specific calibers disappear first during panic buying and the factors influencing supply chain disruptions. The advice is geared towards intermediate shooters and gun owners concerned with preparedness.

This video tests the penetration capabilities of various calibers against a boulder, culminating with the .50 BMG. While smaller calibers like .22 LR, 9mm, and .45 ACP caused minimal damage, larger rounds like 5.56mm and 12 gauge slugs began to chip the rock. The .308 and initial .50 BMG shots caused significant fragmentation but did not penetrate. A second .50 BMG shot successfully penetrated the boulder.

This video provides expert advice on stockpiling essential ammunition calibers in anticipation of potential shortages, referencing historical patterns and supply chain vulnerabilities. Ted from Line45 emphasizes the importance of maintaining a buffer of training and defensive ammunition for key calibers like .22 LR, 9mm, .223/5.56, 12-gauge slugs/buckshot, 7.62x39mm, and .308/7.62 NATO. He advises prioritizing calibers based on common use, defensive applications, and vulnerability to market fluctuations.

This video demonstrates universal shooting standards, emphasizing under one-second engagement times from high and low ready positions. It showcases drills like the Bill Drill and a 3 Body, 2 Head sequence, highlighting efficient weapon manipulation and accuracy with a custom AR-15 build featuring an EOTech optic and GBRS Hydra Mount.

This guide, based on instruction from DJ Shipley of GBRS Group, details the critical importance of proper posture while wearing body armor. It emphasizes standing upright and squaring plates to the threat to maximize ballistic coverage, contrasting this with the dangerous practice of leaning forward, which can expose vital areas. The instruction highlights techniques for effective protection in tactical scenarios.

This GBRS Group video emphasizes mastering carbine reloads by prioritizing proper technique over raw speed. It highlights the critical importance of a firm, forward support grip (like a C-clamp) for weapon control during CQB and high-stress scenarios, warning against sacrificing fundamentals for fast 'par times'. The correct sequence involves sending the bolt, moving the support hand forward, establishing a solid grip, and then re-acquiring the target.

This video showcases a rigorous durability test of the SIG Sauer P320 pistol equipped with a ROMEO-M17 optic and SureFire X300U-B weapon light. Performed by a former Tier 1 operator from GBRS Group, the test involves repeatedly slamming the pistol against a table and dropping it onto gravel to assess zero retention and overall reliability under extreme conditions. The results demonstrate the ruggedness of the optic and firearm setup for demanding operational environments.
