Lancer Systems L6SCM Magazine: Making History With a GunMag Warehouse Exclusive

When the U.S. Army chose a manufacturer to award the contract to for the production of their NGSW (Next Generation Squad Weapon), it wasn’t only about the guns themselves. Reliable, well-made magazines are a key part of a firearm, especially when the gun in question will be used in combat. The magazine cannot be the weak point. So when it came time to select a company to handle magazines, Lancer Systems became the clear choice. Their L6SCM magazine is made for not just serious use, but combat use, and now you can get one (or more) for yourself, exclusively at GunMag Warehouse and Lancer Systems!

The Lancer Systems L6SCM is part of the military’s transition from the M4/M4A1 platform to the new NGSW which was first called the XM5 but is now designated as the XM7. As time as has passed, the original L6SCM that won the contract was changed to a steel magazine. The magazine itself did not change, the materials simply did. This magazine is made for the NGSW 6.8x51mm round which promises to be the next big thing for CQB (close-quarters battle) and duty use.

This magazine has a durable, proprietary polymer body. It’s surprisingly lightweight considering its impressive strength and is designed to be translucent, making it easy to do a visual round count. The smoky color of the body reduces the risk of glare and also helps it blend into the background a bit. It also has hardened feed lips.

Features of the L6SCM include:

  • Feedlips: Lancer utilized a coining process developed for the specific purpose of minimizing friction on the feedlip/cartridge case interface which facilitates smoother chambering and improved reliability.

  • Follower: The follower was specifically developed around the 6.8x51mm for superior feeding.

  • Spring: The mainspring was redesigned to distribute force evenly with the ‘Empty’ load as a constant force between configurations. This feature also delivers a dependable Bolt Hold Open interface. The full load point was designed for the 6.8x51mm cartridge weight and made to consistently handle full-auto.

  • Floorplate:  .050 inches of material was removed to allow optimal spring compression and loading when the bolt is closed.

  • Wear indicator:  A wear indicator is laser engraved on the front of the feed lips and serves as a visual indicator that the magazine is worn out and should be replaced.

The magazine was built for use with the 6.8x51mm, but it has demonstrated bolt-hold open compatibility in testing with AR-10/SR-25 rifles in .308 Winchester and 6.5 Creedmoor (function is NOT guaranteed with these chamberings or SR-25-spec firearms). These mags are available in limited quantities, giving gun owners the opportunity to own a unique piece of gun history.

MSRP for the Lancer Systems L6SCM is $56.99.
