This guide addresses a common issue with some PSA Sabre AR-15 upper receivers identified by the speaker, Cody. The problem stems from improper milling of the internal receiver walls, leading to excess material that obstructs the magazine well. This can cause significant difficulty in seating and removing magazines, even if the rifle functions once loaded. The guide outlines visual inspection and functional testing steps to diagnose this defect.
