Description
The Ergo Gapper is a rubber gap cover designed to seal the space between your AR-15’s upper and lower receiver. Built from durable black rubber, it slides on easily without tools and provides real protection against mud, dust, and other field debris working into your rifle’s internals. Whether you’re running a precision build or a hard-use hunting rig, the Gapper is a no-fuss accessory that extends the time between cleanings and helps keep your AR running reliably. Works with any AR-platform rifle using a standard M4 profile upper and lower.
