Did not fit - Strike Industries AR-10 Shift Takedown Pins

I have a POF-USA 308 AR and these pins did not fit. The pin diameter is bigger than what my rifle takes. My POF-USA AR10 uses same diameter pins as AR15s but the front pin is longer. Not sure if this is the case on a lot of AR10s or just mine. I'll Save the set for a different lower and see. Very cool looking and well made pins, came with new springs and dents and are made for easy assembly/disassembly. I only wish i could have used them.
