FS ar flattop riser

I have a flattop riser for lifting your optics about 1/2 inch. I am not sure of the maker of this but the rifle it came on was done up with only the best stuff and it is in excellent shape. It is of very good quality and I am sure you would like it. Asking $30 shipped to the lower 48. Please email me at [email protected] for pics or offers.

Thanks,
Ghilly
