LMC pre-production is a short run of LMC (Low profile, duty, Magazine Catch). Instead of the shortened shaft and taller"bump" on the magazine plate (the part that engages the magazine's cut out), LMC pre-production uses TDP spec shaft length and bump height.
Production LMC ETA is summer of 2020.
Billet machined in 4140 steel and black nitrided, LMC pre-production is shipped with a 10.9in/lb magazine catch spring. The 10.9 inch/lb magazine catch spring was first introduced in 2017, we had stiffer springs custom made for our EMR-A (ambidextrous magazine catch). The 10.9 in/lb spring's role is to offset the mechanical advantage afforded by EMR-A's lever, it also has the direct result of making the right side magazine release button harder to press, which we view as a positive.

Proudly designed and made in the USA.
For 308 AR users, AR15/M16 spec magazine catches work best with taller magazine release buttons, such as the EMR-HC and EMR-HC, AA. The taller profile accommodates the thicker 308 AR receivers. EMR-HC and EMR-HC, AA will still stay flush or below the magazine release fence on the right side of the lower receiver.
