Product Spotlight: Bravo Company Mk 2 Recoil Mitigation System

This video from GUNBROS explains the function of a buffer tube on an AR-15 or AR-pattern rifle. As demonstrated by the instructor, the buffer tube is attached to the lower receiver and houses the buffer and spring. When the rifle fires, the bolt carrier group compresses this assembly, which then returns forward to chamber the next round. The video emphasizes the critical role of the buffer tube in the AR-15's operating system.

This entry details the significant evolution of the AR-15 platform over approximately 15 years, as explained by an experienced firearm enthusiast. Key changes include the widespread adoption of M-LOK aluminum handguards over older plastic or quad rail systems, the transition to low-profile gas blocks and mid-length gas systems, and variations in barrel twist rates. Consumer demand has been a primary driver of these improvements, leading to better value and features in modern AR-15s.

This guide details the installation of an Armaspec ELEV8 Series Plank Optics Riser mount onto an AR-style rifle, as demonstrated by AT3 Tactical.

This video demonstrates an experiment to determine if a suppressor can effectively muffle the sound of a blank round fired from an AR-15 platform rifle. The test involves firing both blank and live rounds through a suppressed setup, highlighting the significant muzzle flash produced by blanks and the potential for ejection issues. The demonstration suggests that suppressors do muffle blank rounds, prompting questions about their practical applications.

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.'
