Is it possible.....

[fishnfrank]

I have an FR8 308 and was wanting to build a suppressor ( legally with paperwork of course) and install it. I would only do it if I didn't have to modify the rifle. It has a flash suppressor on it and locking rings behind that. I have never done anything like this but I would like to try. Does anyone know if this is possible without modding the gun? Thanks and Merry Christmas!!
