Greyfox hang on. When I check the gun again I will be back. I know the stock is a magpul carbine (milspec 368). Also the gas block slides on with ease. So should be able to use a rifle length spring if everything is built correctly or using the carbine spring means Iam compensating something to make it work. Is it ok to replace a rifle length gas system to substitute a carbine length spring as long as everything cycles normal? If I built the gun correctly would t be talking about spring substitutes?
