Mounting Block

Description

Grab an extra mounting block that attaches to the upper receiver for quick changes between uppers using standard detent pins. These blocks are M-LOK and KeyMod™ compatible and are CNC machined out of aircraft grade, 6061-T6 aluminum, anodized black. Great for use with multiple calibers/uppers while running the same mil-spec lower, with our Scy attached. Switch between rifle caliber and pistol caliber carbine by swapping uppers and installing a magazine adapter block.
