Been searching the interwebs for a while now and have been looking at videos. I can't seem to find a .308/large platform specific forward assist ? Does it take a special FA or do I just install a standard AR15 FA ? Any one know of where I can get the dust cover, spring, circlip, and all in a single kit for this rifle as well ? Finding a rifle length tube, .308 buffer and spring has proven to be a bit of a challenge and I am dead set on the PRS stock so no else will work. Please help a knooby and guide me down the path to SUCESS !!! Oh yeah what are you guys using for gas tubes on your DPMS SASS barrels I have the block and barrel just no gas tube.....
