I got a AXCS Chassis from Europtic for a R700 SA in FDE, whom I must say had excellent customer service. My question is what do I need to get to install it? Do i need a torque wrench? can you make any recommendations as far as torque wrenches and drivers? I have also been told that I need to get High rings as well for my NF NXS 3.5-15 to clear the rail section on the foreend. Discuss!
