Upper / Lower Receiver Tensioning / Accurizing Wedge - Single
Tightening the fit between loose AR-15 or AR-10 upper and lower receivers is quick and simple with these drop-in tensioning / accurizing wedges. Installs in seconds and can greatly improve accuracy by reducing un-necessary upper receiver wobble.
Simply open your upper receiver; insert this wedge behind and under the takedown pin as shown in the example photo here and snap your lower and upper back together. While no modifications are typically required you may find that some minor trimming will allow a more proper fit with your exact upper / lower set.
- High-density, high heat resistant injection molded rubber
- ½" (12.5mm) long
- Works with both AR-15 and AR-10 platform receivers
