Both the upper and lower receivers of the M4-SBR-L are machined from 7075-T6 aluminum billet and hardcoat anodized in a variety of colors. Since Franklin Armory uses CNC machines to carve out each receiver from a solid block of aluminum alloy, giving them a distinctly beefier look than usual, the company can also add custom features directly to the parts. The lower receiver has an integrated and enlarged triggerguard for ease of use with gloved fingers. At the front of the triggerguard and just above the magazine well is a grooved memory tab for finger-off-the-trigger safety (at least for right-handed shooters). The magazine well itself is significantly flared to aid with faster magazine reloads, and the front of the magazine well features a checkered pattern to provide extra grip to those who like using it as an improvised vertical grip.
