I just swapped in a Spikes Nickel Boron BCG into my brand new Larue upper, everything works great except when I try to do a press check or rack the bolt on a loaded chamber the bolt is very resistant. The gun cycles great and I have had no other malfuctions. I have about 250rds through it now and it seems to be getting easier to rack the bolt...think it just needs to be broke in more???
