Product Spotlight: SIG MCX Spear Next-Generation Battle Rifle

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.

This review of the Sig Sauer MCX Spear LT highlights its evolution from the NGSW program's M7 rifle, focusing on its lighter, commercial variant optimized for standard calibers like 5.56 NATO.

This video discusses the U.S. Army's transition away from the 5.56mm and 7.62mm rounds to the new 6.8x51mm cartridge. It highlights the capabilities of the new caliber, developed under the Next Generation Squad Weapon program, emphasizing its increased range, power, and armor penetration. The video also mentions the new firearms and optics paired with this cartridge, including the SIG Sauer M7 rifle, M250 automatic rifle, and XM157 Fire Control optic. It aims to explain why the older calibers are no longer sufficient for modern warfare and positions the 6.8x51mm as a significant advancement in infantry firepower.

This video from CF Clips discusses the progress of the Next Generation Squad Weapons (NGSW) program, specifically highlighting the Sig Sauer XM7. The instructor notes that Sig Sauer is actively delivering these weapons, distinguishing this effort from previous failed replacement programs.

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.
