Does the bolt come back and stop with no magazine in place? If so, you have some sort of interference issue between the BCG and receiver or buffer and tube.
If its just hanging up with the magazine in place, try another magazine, preferably a recommended brand magazine (Duramag maybe?)
Rifle +1 gas system on an 18" barrel doesn't leave much barrel length beyond the gas port for dwell time. If it is a lack of gas problem, it could be the gas port doesn't line up with the gas block, or too small of gas port. A lightweight BCG is another option to try.
