UTG® receiver wedge for AR15 / M4 / M16

A small but crucial component for anyone who wants to get the maximum out of their AR15. The UTG RB-A005 rubber receiver wedge strengthens the connection between the upper and lower parts of the weapon's body, thereby improving its overall operation and stability.

Better fit. Greater accuracy. Less play.

The rubber wedge simply slides into the lower receiver and is slightly compressed when connected to the upper receiver. The result is a tighter and more stable contact without unnecessary micro play, which can affect both accuracy and the subjective feel when handling the weapon. The entire assembly thus feels firmer, more compact and more professional.

Simple installation, immediate effect

No modifications or tools are needed – you just insert the buffer in the right place. This small and inexpensive upgrade can noticeably improve the overall behavior of the weapon, whether it's a new build or an older piece that has seen some use. An ideal accessory for anyone who likes everything to fit perfectly.
