AR-15 Accu-Wedge

This 3d printed part is used to help reduce loose fit between the upper and lower assemblies on an AR-15.

Instantly Tightens Loose Upper & Lower Receivers

Helps promote better accuracy by making the upper and lower receiver fit tighter. Open upper receiver; drop this long-wearing, rubber wedge into the rear of the lower, behind the push pin. Absolutely no modifications required.

Takes less then 5 mins to print on my XYZ printer and uses less then a meter of filament.  A must have to keep your receiver nice and tight regardless of if you believe it to make your gun more accurate.  Originally printed on a XYZprinting Da Vinci 1.0 3D Printer, Grey Find this on thingiverse here http://www.thingiverse.com/thing:635723
