I have for sale KX3 flash hider/flaming pig threaded for 6.8SPC Rifles - 5/8x24. If you are interested and you own a Stag 5H/L upper, you may want to check the thread size. My Stag 5HL came with a different thread size other than 5/8x24, therefor this flash hider has never been installed. 80$ shipped discreet PP.
