[SHOT 2018] CMMG's New .224 Valkyrie Precision Rifle and 9mm Glock Mag Guard AR

This video from SHOT Show 2018 features CMMG's Mk4 DTR2 rifle chambered in the newly introduced .224 Valkyrie cartridge. The description highlights the .224 Valkyrie's suitability for long-range shooting and CMMG's approach to building an optimal rifle platform for this round.

This video from SHOT Show 2018 features Mike from CMMG discussing their new firearms, including the .224 Valkyrie, the CMMG Guard, and rifles chambered in 6.5 Creedmoor and 6.5 Grendel. The presentation covers new product announcements and likely provides insights into CMMG's offerings for the year.

This review of the CMMG Guard 9mm carbine highlights its innovative Radial Delayed Blowback system, which significantly reduces felt recoil and improves reliability compared to traditional straight blowback designs. The firearm demonstrated excellent performance with various ammunition types and a low malfunction rate over extensive testing. While praised for its handling and potential for home defense, a key drawback is the 1/2x36 barrel threading, limiting immediate suppressor compatibility.

This video is a "Gun of the Week" review of the Robinson Armament XCR-L rifle in 5.56mm. The presenter compares it favorably to the FN Scar 17, highlighting its ergonomics and quick-change barrel system. The video covers the XCR-L's multi-caliber capabilities (.223, .224 Valkyrie, .300 Blackout, 6.8 SPC, and 7.62x39mm) and discusses Canadian firearm regulations regarding barrel length and licensing (PAL/RPAL). The creator also uses this video to promote their Patreon for supporting future content production.

The .224 Valkyrie shows promise for the AR-15 platform, offering high ballistic performance with 90-grain bullets. Early testing revealed potential issues with velocity consistency and accuracy, often linked to reamer depth, freebore, and twist rates. Enhancements like receiver lapping and specific barrel configurations (e.g., 1:6.5 twist) significantly improved accuracy, yielding sub-MOA results.

The CMMG Mk57 Banshee in 5.7x28mm is a lightweight PDW offering impressive accuracy, with Federal American Eagle 40gr FMJ achieving a 0.5-inch group at 50 yards. Its Radial Delayed Blowback system significantly reduces recoil. Suppressed shooting with subsonic ammo requires a lighter buffer for reliable cycling. The pistol accepts FN Five-seveN magazines and has an MSRP of $1500.

This TFBTV episode identifies the top 5 most reliable firearms across different categories: Glock (handgun), Uzi (SMG), Mauser 98 (bolt-action), Remington 870 (shotgun), and Galil (self-loading rifle). The selections prioritize mechanical simplicity, proven track records, and resilience in harsh conditions, often outperforming more complex designs. The video highlights specific features contributing to their reliability, such as the Uzi's single moving part and the Galil's robust construction.

This review highlights five hilariously impractical firearms for concealed carry. It details the slow, complex loading of black powder firearms, the impractical size of the Mauser C96 and full-size .22 pistols for concealment, and the dangerous accidental discharge flaw in the Type 94 Nambu. The video emphasizes that while historically significant, these guns are unsuitable for modern self-defense.

The Ruger Mini-14 offers distinct advantages over the AR-15, including a lower profile, better stock trigger on modern variants, superior maneuverability with folding stocks, a longer sight radius, and a cleaner piston operating system. Modern Mini-14s also boast improved accuracy (around 2 MOA), cold hammer-forged barrels for durability, and optional all-stainless construction for corrosion resistance. While the AR-15 remains more modular and generally cheaper, the Mini-14 excels in specific areas.

This TFBTV episode reviews five excellent surplus rifles available for under $500, focusing on historical significance and affordability. Featured firearms include the Lee Enfield, Yugoslavian Mauser 98, Swiss K31, MAS 49/56, and a debate between the SKS and Mosin Nagant for the final spot. The discussion highlights unique actions, historical context, and the availability of surplus ammunition.
