The ACCU - Wedge is one of the easiest parts to install in a AR-15. This component adds stability and eliminates any chance of unwanted noise or rattle between your upper receiver and your lower receiver. Installation is a breeze. The ACCU - Wedge slides into the lower receiver behind the rear take down pin and will ensure a snug fit.
Trimming of the lower section may be necessary to make it fit perfectly. This is easily done with a razor blade.
