This review delves into the 2.7mm Kolibri, the world's smallest centerfire pistol, designed by watchmaker Franz Pfannl. Despite its intricate, semi-automatic blowback operation, it's noted as underpowered for self-defense, firing a 3-grain projectile at 650 fps. Approximately 1,000 were made before WWI, and the video showcases its original presentation case with accessories.

This review delves into the rare Erika 4.25mm pistol, a compact semi-automatic blowback firearm designed for personal protection. The discussion highlights its unique 4.25x10.6mm cartridge, comparable to a .17 caliber, and its remarkably small size and weight.

This video details the installation of a Geissele MK8 Super Modular Rail on an AR-15. Key steps include using a Geissele Reaction Rod for upper receiver stability, proper torquing of the proprietary barrel nut, and secure installation of the gas block and tube. The rail is then slid on and secured with two cross-bolts using a T-handle hex wrench. Final steps involve muzzle device installation and a thorough inspection.

Proper ammunition storage is crucial for maintaining reliability and safety. Avoid storing ammo in cardboard boxes in damp environments, as this leads to moisture absorption and corrosion. Utilize airtight containers like ammo cans and control humidity with desiccants like silica gel packs. Heat accelerates gunpowder and primer degradation, so store ammo at stable room temperatures. Reloading primers are particularly vulnerable to moisture and require strict airtight storage.

This video demonstrates how to upgrade an AR-15's A2 furniture to Magpul components. It details the removal of the A2 grip using a Bondhus hex set and the installation of a Magpul MIAD grip with interchangeable backstraps for improved ergonomics. The process also covers preparing and installing the Magpul PRS stock, highlighting its adjustable features for cheek weld and length of pull.

This video explores the custom Remington 11-87 shotgun used as a prop in 'No Country for Old Men.' The film required a semi-automatic shotgun with a suppressor, a combination not readily available at the time. Prop master Larry Zanoff details how a non-functional, 'homemade' looking suppressor was custom-built for the 11-87, with the iconic silenced sound effect achieved entirely in post-production.
