The UTG Model 4/AR15 Receiver Wedge is a simple, purpose-built accessory designed to tighten the fit between your AR-15 upper and lower receivers. Installed near the rear takedown pin, this bright red wedge applies gentle pressure to the upper, helping to reduce play, improve consistency, and extend the life of your rifle’s mating surfaces.

This receiver wedge is ideal for shooters who want a more solid, refined feel from their AR platform during range sessions, training, or general use. By minimizing rattle and vibration, it can contribute to more repeatable performance and a quieter, more confidence-inspiring rifle. It is a small, affordable upgrade that reflects UTG’s focus on practical, user-friendly accessories for modern sporting rifles.
