Hi just recently purchased a Dpms lr 308 and it is the first AR I have ever purchased, and only the second gun I’ve owned. ( First is a SE-17 Semi Shotgun) I’m looking to modify or personalize it but I simply don’t know where to begin, I want to get a fore grip of some sort and the ability to run close and long range set ups. Could anybody point me in the right direction? I found a 5slotted picatinny offset rail and was wondering if I could run a red dot sight and scope at the same time while being accurate. Thanks for your time
