Have not really dug into the gun yet but the immediate thing that stands out is an 18" barrel on a carbine gas system. This is extremely unbalanced regardless of port size. Extension is probably off on dimensions. Upper is Cardinal but I do not know who cut it, anodize looks good but no internal PTFE. Rail is a rail but I need to dig under this to see how the barrel nut is set up. Your gas tube is leaking from the block and hitting the gas key. The gas key is well staked with piss poor screws. Does not look to be chrome lined.
Initial look at the lower, hate the acuwedge and your trigger groups is under sprung. Going to pull the recoils spring and check coil count, free length and K value. Need to check alignment of the buffer tube to the center axis.
