This AT3 Tactical video addresses the common question of how to time an AR-15 flash hider. The instructor, demonstrating expertise in firearm components, highlights that while many flash hiders vent gas to the sides and bottom, some users opt for upward and downward venting. Viewers are encouraged to share their preferred methods in the comments, indicating a community-driven approach to this installation detail.

This video introduces the Strategic Sciences MFMD, a 3D-printed, over-barrel device that functions as a suppressor, flash hider, and muzzle brake. It offers significant sound, flash, and recoil reduction, with variants like the SDX achieving near-zero signature. The expert-level demonstration highlights its innovative design and practical performance on various firearms, including machine guns.

This video from Brownells features Caleb spotlighting the Rearden Manufacturing Atlas Muzzle Devices. The Atlas system is a versatile suppressor mounting solution designed to be compatible with Plan B adapters, enabling a universal thread-on system for suppressors across various firearms. The video highlights key benefits, including how the tapered mounting design prevents carbon lock, reduces overall length, and improves suppressor fitment. It also showcases a blast can option for users who don't plan to use a suppressor. The content covers installation, threading, and available options like flash hiders, muzzle brakes, length variations, and caliber choices.

This video introduces a novel 3-in-1 multifunction muzzle device from Strategic Sciences, presented at SHOT Show 2024. The device uniquely combines the capabilities of a flash hider, compensator, and suppressor into a single unit, aiming to offer comprehensive performance benefits without the usual compromises. Russell Joseph of Strategic Sciences highlights its hybrid design, which addresses the historical need for shooters to select only one primary function.

This video from SHOT Show 2026 introduces the Strategic Sciences MFMD, a 3D-printed Inconel 718 muzzle device that functions as a suppressor, flash hider, and brake. It offers significant recoil and flash reduction, with options for various calibers and extensions. The device is NFA serialized, with the muzzle device itself being the regulated component.

This short demonstrates the ballistic power of the .500 Auto Max cartridge fired from an AR platform rifle. The video showcases a test where the round obliterates a water-filled protein powder tub, highlighting the round's destructive potential. The presenter, exhibiting clear familiarity with large-caliber firearms and ballistics, conducts a visual demonstration of the ammunition's impact.

This video explains the importance of proper red dot sight zeroing for firearms. It highlights the common mistake of zeroing at 5 yards, which leads to inaccurate shots at longer distances due to the sight's height over bore. A 15-yard zero for 9mm handguns is recommended for a flatter trajectory, hitting the point of aim at 15 yards and often again at 50 yards.

The Kel-Tec P50 is a unique firearm chambered in 5.7x28mm, notable for its extremely lightweight design and surprisingly low recoil, even with a 20-round capacity. Despite a long trigger pull, its performance, with a 40-grain projectile at 1600 fps, offers comparable stopping power to .380 ACP with less felt recoil. The P50 utilizes an unusual top-loading stripper clip mechanism.

This video emphasizes aiming for the pelvis in defensive scenarios, explaining its structural importance for immobilizing a threat. It highlights this technique as effective against body armor and taller opponents. The content features a 2011-style pistol with a red dot optic and discusses tactical target selection with a humorous, direct approach.

This video clarifies the true purpose of co-witnessing red dot sights with iron sights. It emphasizes that they should operate independently, with the red dot's position within the optic window not affecting the point of impact due to parallax-free design. Co-witnessing is primarily for backup when the electronic sight fails, not for simultaneous aiming.
