New for 2018: Brownells Retro XM177E2

This video details a significant durability test of the Brownells BRN-4 rifle after it experienced a catastrophic failure due to a faulty ammunition round. The speaker, from Regular Guy Training, highlights the rifle's exceptional resilience, noting minimal damage and no performance degradation after firing an additional 4,000 rounds post-incident. This demonstrates the BRN-4's robust construction and ability to withstand extreme stress.

This evaluation of the Brownells BRN-4, conducted by Regular Guy Training LLC, details a year-long assessment involving 21,000 rounds. The speaker, a professional firearms instructor, highlights the rifle's robust performance under 'spotty' yet intense usage, including its function as a loaner for students with rifle failures. The insights are derived from personal experience and observation of numerous students.

The AKB-23 is a new bullpup lower receiver designed for AR-15 based bufferless uppers, aiming to replicate the SA80/L85 form factor. It's constructed from billet aluminum, priced around $800, and compatible with uppers like the Brownells BRN-180, PSA Jackl, and FM-15. Testing indicates good reliability, with production underway.

The Brownells BRN-180 Gen 3 upper receiver is showcased in a visually driven review. Key features highlighted include its side-charging handle, bufferless design, and compatibility with .223 Wylde and 5.56 NATO calibers. The setup includes a Meprolight M22 optic and suppressor, demonstrating a high-end tactical configuration.

The Brownells BRN-180 Gen 3 introduces significant upgrades, including a closed system to prevent debris and a left-side non-reciprocating charging handle. It features functional improvements like QD sling points and an adjustable gas system. Pre-release testing showed promising reliability, with only one malfunction in 400 rounds.

This review covers the Brownells reproduction of the Colt 4x20mm AR-15 scope, manufactured using original 1970s blueprints and manufacturer. It features authentic markings, a duplex reticle, and a BDC turret calibrated for 100-500 yards. The scope mounts directly into an AR-15 carry handle and offers improved modern glass quality while maintaining historical accuracy, making it ideal for retro builds.

This video hilariously tests a heavily accessorized AR-15, dubbed the 'Zombie Carbine,' as a parody of excessive tactical gear. The build, based on a Smith & Wesson M&P15, weighs 23 pounds fully loaded with 270 rounds across nine magazines. It features multiple optics, lasers, lights, and is demonstrated with rapid fire, hip sniping, and Tannerite explosions.

This "ultimate AR-15 meltdown" test pushes a custom build to its limits, revealing key durability insights. The Faxon barrel ultimately burst after 830 rounds, but critical components like the Sharps SRC bolt carrier group and Geissele rail demonstrated impressive resilience under extreme stress and heat. The test highlights the AR-15 platform's robust design, even when subjected to conditions far exceeding typical operational use.

This video showcases an extreme full-auto durability test of a premium Definitive Arms VEPR AK, comparing it to a budget WASR-10. The VEPR AK demonstrated exceptional resilience, enduring 895 rounds before failure, significantly outperforming the WASR-10 and even a previously tested AR-15. The expert analysis highlights the AK platform's inherent durability and heat management characteristics, even under severe stress.

This video demonstrates the legendary durability of the AK platform by subjecting a Yugo M92 PAP to a 700-round continuous firing test. Despite extreme heat causing significant smoke and glowing metal, the firearm remained functional, showcasing Mikhail Kalashnikov's robust engineering. The test concludes with a cooling process and a tribute to the designer's legacy.
