Clean and inspect it. Assuming you're using correct .308 ammunition (sounds like it), it could be a number of things.
New guns often need cleaning. Very old ones may have lubrication that is drying out, and brand new ones may have chip and manufacturing debris. In any case the barrel may have oil and should be cleaned out.
How does it feel when you manually cycle it? Can you see where the ejection gas tube is in the proper position under the front grip and properly in contact within the bolt ejection port? Is the action rough or smooth?
Sometimes the problem is the support you're giving the rifle to allow it to recoil properly and then spring back and reload the next round. Is it tightly supported against your shoulder?
Is the magazine fully inserted? Are both feed ramps into the barrel properly machined and clean?
Photos may help diagnose what you're dealing with.
