Brownells BRN-180™ Gen2 - An Introduction

This video introduces the new Brownells BRN-180S™ upper receiver, a short-barreled variant of the acclaimed BRN-180™. Featuring a 10.5" barrel, it's designed for AR pistol or SBR builds. A key feature is its adjustable gas system, allowing for easy switching between suppressed ('S') and unsuppressed ('U') operation, developed in collaboration with Primary Weapon Systems (PWS) and FM Products. The video also includes a brief overview and disassembly of the AR-180 operating system.

The Brownells BRN-180 upper receiver is a modern adaptation of the AR-180's short-stroke piston system, designed to fit standard AR-15 lower receivers. It features a monolithic Picatinny rail, M-LOK handguard, and a self-contained recoil system allowing for folding stocks. The design prioritizes reliability and reduced recoil, with a stable trunnion mounting system and a sub-$800 MSRP.

This video provides a detailed comparison between the BRN-180® Gen 2 and Gen 3 rifles, presented by Caleb from Brownells. Key upgrades discussed include the transition to a non-reciprocating charging handle, a refined three-position gas piston system, and an improved steel cam path to address over-gassing. The presenter also highlights updates to the dust cover and handguard attachment design, emphasizing the Gen 3 as a shooter-focused evolution of the classic platform. Component compatibility and user feedback are also touched upon, offering a comprehensive overview for enthusiasts.

The Aly & Kaufman AKB-23 is a bullpup conversion kit for the Brownells BRN-180, designed to replicate the feel and ergonomics of the British SA80/L85 rifle. Utilizing the AR-180's mechanical lineage, the kit offers an affordable way to experience the bullpup platform. It features a milled aluminum lower and 3D-printed furniture, with assembly requiring integration of the BRN-180 upper. Performance is noted as reliable, providing an authentic handling experience.

The BRN-180 showcases a modernized, bufferless AR-18 design, allowing for compact operation with a side-folding stock. Its short-stroke gas piston system ensures reliable cycling and consistent ejection, even during rapid fire. The video highlights ease of maintenance, including lubrication through the ejection port, and demonstrates its capability to fire with the stock folded.

The Brownells BRN-180 upper receiver offers a modern interpretation of the AR-180, featuring a piston-operated system compatible with standard AR-15 lowers. Its design allows for folding stocks and includes a reciprocating side charging handle, adjustable gas system, and M-LOK handguard. While offering smooth recoil and minimal gas blowback, the handguard can heat up significantly during sustained fire.

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.
