I have this barrel as well and actually returned my SLR gas block because it wouldn't even fit my SLR rail...so, make sure you pay attention to the schematic they have posted. It looks like it will fit but after I talked to them they said it wouldn't. I'm stuck now trying to find an adjustable .875 gas block that will fit a rail. Other than that my build will be complete. Any suggestions for the OP and myself?
