This is my .223 Sagia with a simple bolt on forearm piece by Tapco, called Intrafuse. When I got the kit, you can add which or all of the rails you want, and there are 2 front adapters. One is for .223/7.69 and the other is for .308 So I am quite sure it, with the front adapter, could fit on the .308.
