This video showcases the installation of a three-position Force Reset Trigger (FRT) on an Arsenal 107 SBR AK platform. The presenter demonstrates the functionality of the FRT, highlighting its semi-automatic, force reset, and full-automatic modes. The video also includes a brief test firing session with both supersonic and subsonic ammunition to illustrate potential differences in recoil and sound.

This video details a highly dangerous experiment where a 50 BMG round is heated on a stove, likened to cooking a 'forbidden hot dog.' The speaker, exhibiting experienced authority, highlights the extreme risks involved, even retreating behind a truck for safety. The experiment results in the destruction of the pan and a hole created by the base of the 50 BMG round. The conclusion strongly advises against such actions due to the inherent dangers.

This guide explains the functionality of the new Progressive FRT system found in the X-PRT90 for the P90 firearm. Instruction from an experienced firearms instructor details how to achieve both semi-automatic and full-auto fire modes using different trigger pull depths and releases, emphasizing the unique forward reset mechanism.

This video explores the compatibility of a 50 BMG cartridge with a 12 gauge flare gun. The experiment reveals that while the cartridge fits, the flare gun's mechanism cannot ignite the tough 50 BMG primers. However, it successfully fires a standard 12 gauge blank, highlighting the difference in primer hardness. The content is presented from a hobbyist perspective, focusing on experimental curiosity rather than professional instruction.

This guide details the field stripping process for the Smith & Wesson M&P 22X, as demonstrated by an expert firearm reviewer. It covers the essential steps for safe disassembly, cleaning, lubrication, and reassembly, highlighting the fixed barrel design common to this class of .22LR pistols. The process is presented with a strong emphasis on safety protocols, crucial for any firearm maintenance.

This guide details the disassembly and reassembly of a Benelli M4 shotgun, focusing on the removal and replacement of the handguard. It demonstrates safe firearm handling and proper loading techniques. The video showcases fluid field stripping and reassembly, highlighting the semi-automatic action of the Benelli M4.

This guide details the complex process of converting a lathe into a 12-barrel blank-firing gun, as demonstrated by Mark Serbu. It highlights the critical engineering challenges, including precise alignment, CNC control, and the application of PID theory to overcome firing inconsistencies. The project emphasizes safety and legal considerations, focusing on blank ammunition to avoid machine gun manufacturing regulations.

This video demonstrates how to rifle a barrel in a home shop using basic tools, bypassing expensive CNC equipment. It covers material preparation, precise drilling and reaming, and the critical process of pushing a rifling button. While a DIY approach is shown to be possible, the video highlights the significant difference in quality and precision achievable with professional CNC machining.

This video provides an expert-level analysis of a catastrophic failure of the Serbu RN-50 rifle, presented by the firearm's designer, Mark Serbu. The examination focuses on the severe damage to the receiver, breech cap, and barrel assembly, offering insights into potential failure points and the effects of extreme forces. The analysis also touches upon the ammunition used, specifically SLAP rounds, and their potential role in the incident.

Mark Serbu, a gun designer, addresses the RN-50 blow-up incident involving Scott from Kentucky Ballistics. Serbu reassures customers that the RN-50 is a safe design, attributing the incident to a counterfeit and faulty ammunition round. He emphasizes the importance of sourcing ammunition carefully and highlights the rifle's extensive safe operational history.
