| Hey does anyone know what height riser I will need to place on my Stag arms Optics ready upper (on the gas block) so the front and rear sight will be co-witness- I can't tell if it's 1/4 or 1/2, I e-mailed Stag Arms today , but I can't see me getting a response from them till next week. Any input would be great. |
