The uppers use standard pin sizes, making them broadly compatible with most AR-15 lower receivers, but they are being sold in NRA-rated Fair to Poor surplus condition, meaning they likely show significant wear, corrosion, or damage. The listing also warns that they may not be in working order, so they should be viewed primarily as parts, restoration candidates, or collector items rather than ready-to-use components, and buyers should carefully review photos to assess their actual condition and completeness.
