Shims for AR15 front Body Receiver Pin

In the case of cheaper airsoft bodies M4/16 (sometimes unfortunately even with more expensive brands), we often encounter issues with the wobbling upper receiver. This problem also affects performance, as the wobbling upper half of the body can slightly move with the chamber, thereby worsening performance consistency and logically, accuracy. The wobbling body can also cause feeding problems due to the misalignment of the chamber axis with the barrel in the mechabox.

EPeS thinks of everyone, so if you don't want to buy a CNC-milled body but want to reinforce your sweetheart and give it care, then this small upgrade is just for you.
The pads are placed in the gap between the protrusion of the upper receiver and the lower one, passing through them the front pin. This eliminates the space for wobbling, solving the situation.
