It depends on what caused the problem as much as how to fix it.
If its just the barrel & shroud incorretly gapped than yes. You use a .004 & a .002 feeler gauge (or the .006 one supplied if you have it) the barrel nut wrench, & one of the hex keys attached to the nut wrench (assuming the factory wrench). The gun is stripped to access the adjustment screw for the spring & set corrrectly first, then the barrel correctly inserted & gapped the shroud slipped on & the nut tightened.
But if the frame has been stretched by uber hot loads or something else then it's toast unfortunately.
