This guide details the considerations for building with Brownells exclusive Mk18 Mod 1 upper receivers. It covers the choice between quad rail and M-LOK handguards, the potential for grenade launcher integration, and recommendations for enhancing shooting dynamics with A5 buffer systems. The video emphasizes the durability and performance of these uppers, even when used with full-auto lowers.

This video from Tactical Fellowship, featuring an experienced instructor, details the engineering goals and design enhancements of the BCM MK2 upper receiver. The MK2 aims to match the weight of a standard M4 upper while significantly increasing its structural rigidity, particularly around the ejection port, through strategic material redistribution and thickening.

The Palmetto State Armory AXR SSP rifle system, showcased at SHOT Show 2026, features a short-stroke piston for reduced front-end weight and enhanced modularity. Key design elements include a user-serviceable barrel nut for home barrel swaps and compatibility with AR-15 components. Available in 5.56 and .300 Blackout, the AXR offers fully ambidextrous controls and is optimized for suppressor use with an adjustable gas system.

This expert-level entry details the FN SCAR 17S, a 7.62x51mm rifle developed for US Special Operations Command. It covers the rifle's history, technical specifications, operational features like its non-reciprocating charging handle and adjustable gas system, and common accessories. The entry also touches upon its reliability, historical adoption challenges, and FN's unique warranty policy regarding suppressors.

The Beretta NARP, the Italian military's new service rifle, features a robust short-stroke piston system designed for exceptional reliability and ease of maintenance. Luca Tremolada from Beretta highlights its successful NATO testing, including firing over 20 magazines in full-auto without issues. The rifle incorporates customer-driven design changes for improved ergonomics and modularity, with a proprietary collapsible and folding stock and an M-LOK handguard. Beretta also offers a 3D-printed Inconel suppressor with a QD system that minimizes point of impact shift.

This entry details the Soviet Dragunov SVD, a semi-automatic sniper rifle designed in the 1960s. It highlights its 7.62x54R caliber, gas-operated short-stroke piston system, and standard PSO-1 optic with an effective range of 800 yards. The SVD's enduring legacy is emphasized through its continued use and the existence of modernized variants from various countries.

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.
