My son recently had a carbon fiber forearm put on his DPMS 24" SS AR-10 Bull Panther. The smith who installed the forearm put the sling swivel stud on the gas block. With a bi-pod attached to the swivel under the gas block and shooting prone, how much effect do you think it will have on accuracy. I haven't shot it yet but my thoughts tell me it's going to play heck with the accuracy. Any thoughts?
