The Leapers Model 4/15 Buffer, also known as the UTG receiver wedge, is a compact rubber insert designed to fit near the takedown pin and keep the upper receiver snug and tight against the lower on AR-pattern rifles. By filling the small gap between the receivers, this simple accessory helps create a more solid, consistent lockup for a cleaner shooting experience.

This lightweight rubber buffer is ideal for shooters who want to refine the feel of their AR at the range or during training sessions. By reducing play between the upper and lower, it can help decrease vibration, minimize wear on contact surfaces, and support more repeatable accuracy over time. It is a practical, low-cost upgrade that reflects Leapers’ focus on functional, user-friendly accessories for the modern rifle platform.
