Kaw Valley Precision AR-15 Anti Walk Pin Kit Features The Kaw Valley Precision AR-15 Anti Walk Pin Kit is machined from 4140 steel in the standard .154 diameter matching factory hammer and trigger pin dimensions for a direct fit on most AR15 lower receivers. Unlike standard factory pins these pins thread into posts on either side of the receiver locking them in place so they cannot walk out of position under recoil. This added retention helps keep the hammer and trigger pins properly aligned which supports a more consistent trigger pull over the life of the fire control group. The kit is intended for use with standard AR15 hammer and trigger groups. Each set includes two posts two wrenches and four screws giving the installer every part needed to complete the swap without sourcing additional hardware. The wrenches allow the posts to be properly torqued down during installation ensuring the pins stay secure through extended use. Because the pins are retained on both sides rather than relying on friction fit alone the kit also reduces the chance of a pin backing out during disassembly or heavy use. The Kaw Valley Precision AR-15 Anti Walk Pin Kit is available for sale at GrabAGun for AR15 owners looking for a simple affordable upgrade to their trigger group retention.
