Purchased an AP4 LR308 (carbine) about two months ago with the the standard free-float tube. I want to change to a 4 or 6 rail system and saw that there are bolt on rail systems for AR15s for about $50 but haven't been able to find for AP4 LR308. Does anyone know of any options for the AP4 LR308 like this or do you have to switch the entire free float tube ($180 plus gunsmith charges)? Thanks,
