I feel so stupid. I had taken off the front and rear sights of my S&W M&P 15-22 and put some cheap holographic thing on it. Now I want to go back to the sights and I CANNOT find them. Getting old means your memory is shot. Anyone want to part with their iron sights at a reasonable price. I didn't check but I bet if I buy them new from S&W it will cost me an arm and a leg. thanks PSP-Ret
