Shooting The NEW NGSW SIG MCX SPEAR 6.8x51mm

The U.S. Army's new M7 rifle, based on the Sig Sauer MCX Spear, faces scrutiny over troop dissatisfaction during testing. Key concerns include reduced magazine capacity (20 vs 30 rounds), significantly increased weight (9.58 lbs vs 6.5 lbs for M4), and potential ergonomic issues like a snagging charging handle and accidental magazine ejections. While the 6.8x51mm round offers increased range and armor penetration, the overall platform may necessitate shifts in tactical doctrine.

The Sig MCX Spear, the civilian variant of the US Army's NGSW, is chambered in the high-pressure .277 Fury (6.8x51mm) cartridge. Its advanced features include a 3D-printed flow-through suppressor that significantly reduces gas blowback, a short-stroke gas piston system, and ambidextrous controls. While heavier than the M4, its superior armor penetration and long-range capabilities offer a compelling trade-off for potential DMR or Special Operations roles.

The Sig MCX Spear, chosen by the US Army for its NGSW program, was subjected to an extreme mud test. While performing flawlessly with the dust cover closed, the rifle experienced significant failures to feed, fire, and eject when mud was introduced directly into the action with the dust cover open. This highlights a potential vulnerability in piston-driven systems compared to DI systems in extremely dirty conditions.

The Sig MCX Raptor prototype offers a compact 'Rattler' profile in larger calibers like .308 and 6.5 Creedmoor, evolving from the MCX Spear program. It features fully ambidextrous controls, a modular stock, and user-level barrel swaps. The 8-inch barrel prototype utilizes gas trap technology for reliability and is expected to be commercially available within 12-18 months.

The GBRS Group, comprised of former Navy SEALs, compares the M4 Carbine to the Sig Sauer M7 (NGSW). While acknowledging the 6.8mm round's superior ballistics for long-range and armor penetration, they find the M7's increased weight and recoil make the M4 more suitable for most assault missions due to its maneuverability and familiarity. The M7 is described as a powerful 'broadsword' compared to the M4's agile 'katana'.

This video features an accuracy test of the Sig SPEAR rifle using new 155gr Match ammunition in 6.8x51 (.277 Fury) caliber. The test follows up on a previous video that evaluated the rifle with 113gr solid copper ball ammo, which yielded approximately 4 MOA groups. The focus here is on the performance of the match-grade ammunition with the SPEAR platform, aiming to assess its precision capabilities.

The Kimber 2K11 Stainless Target offers a compelling middle-tier option in the 2K11 line, balancing features and value. It boasts a lighter 35oz weight compared to the base model, utilizing Kevlar and carbon fiber for its frame and grip. The firearm is noted for its accuracy and comes equipped with a C&H Precision optic plate, making it a solid choice for collectors and shooters alike.

This review covers the new Glock 30 Gen 5 in .45 ACP, highlighting its compact size and power. The speaker notes its inclusion in the Generation 5 lineup alongside the 10mm Glock 29 Gen 5. Visuals showcase the firearm with a SureFire X300 Ultra light and close-ups of its markings, emphasizing its suitability for concealed carry and self-defense.

The Ruger RXM is presented as a compelling alternative to the Glock 19, featuring a modular chassis system that allows for grip module swaps without an FFL transfer. It comes optic-ready with a threaded barrel and Magpul PMAGs, offering significant value at a lower price point than a standard Glock. The review highlights its potential as a 'Glock killer' due to these features and expected Ruger reliability.

This video demonstrates the performance of the Sig Rattler LT in .300 Blackout when paired with the Sig SLX 7.62 suppressor. The host tests both 150-grain supersonic and 220-grain subsonic American Marksman ammunition, noting the significant sound reduction achieved with the subsonic rounds. The setup utilizes a QD mount for the suppressor.
