Had scope mounted at brightwater took it to the range came loose in the rings. Took it back was told scope was installed by gunsmith correctly and if somethingcomes loose again its the mount. Mount is larue. Pirchased troy ind. Mcs m14 upgrade took it to the range and shot 8 inches high made front sight post adjustments on buis nominal shift in impact. Also had 3 light strikes and the entire trigger fell out 4 times and or came unhooked. On the light strikes i was told pmc has extra hard primers. After complaining and sending brightwater employee email which he posted on this blog he was extremely Rude and told me to go to another store and to get my stuff and dont come back while i was in acu's. This was two weapons in a row which had problems after brightwater installed something on them.
