This video provides a clear, step-by-step guide on how to install a single-stage trigger on AR-15 and AR-style rifles. It highlights the process as easy and quick, achievable in under 5 minutes. The video covers necessary tools, the installation of trigger, hammer, and disconnecter springs, as well as the trigger and hammer components. It also briefly touches on how to remove a trigger. AT3 Tactical aims to educate the AR-15 community on building and maintaining their firearms safely and knowledgeably.

Essential AR-15 spare parts include gas rings, buffer springs, extractor springs, and firing pin retaining pins. Shorter barrels accelerate wear on internal components. Measure buffer springs for serviceability: carbine springs should be at least 10 1/16 inches, rifle springs 11 1/4 inches. Keep original mil-spec trigger parts as backups for aftermarket triggers.

This YouTube video provides a comprehensive full assembly of the Rex Zero 1 pistol.

This video, the first part of a four-part series, focuses on the lower receiver of a Ruger AR556. Despite audio issues preventing a reshoot, the reviewer details several problems encountered, including stiff detents, buffer spring issues, receiver extension clocking, under-torqued and unstaked castle nuts, weak hammer springs, receiver extension not engaging buffer detents correctly, notched hammers, insufficient carrier key gaps, and issues with the magazine button and catch leading to binding with PMAGs. The reviewer also notes minor cosmetic scratches. This installment appears to be an in-depth examination of the AR-15 platform's assembly and potential defects.

This video demonstrates the fundamental safety mechanism of a hand grenade, specifically the T G-67 M-SOFT model. It highlights that the grenade remains safe as long as the safety lever (spoon) is held down. Pulling the pin initiates the delay fuse, but detonation is prevented until the spoon is released, emphasizing the importance of maintaining grip for safety.

This video demonstrates the proper application of a DINPRO CAT-style tourniquet for severe leg wounds. It highlights the 'high and tight' placement above the injury and the critical step of tightening the windlass until bleeding stops, emphasizing that while painful, this is essential for saving a life. The presenter, Ziga from Polenar Tactical, showcases expert-level knowledge in trauma care.

This video demonstrates the TAG 18 Smoke White grenade, highlighting its operation similar to a hand grenade but using pyrotechnic powder for smoke. The activation process involves pulling a pin and releasing a spoon to ignite the powder, producing a thick white smoke cloud for concealment or signaling. The demonstration emphasizes safe handling and deployment.

This video demonstrates the FBG-6 Flash Bang 2.0, clarifying that real flashbangs disorient rather than produce movie-like blinding flashes. It highlights the 2-second delay mechanism and the importance of holding the safety lever. An accidental detonation on the range floor showcases its acoustic and pressure effects.
