Here is the deal, I have the Troy low profile gas block adjusted on my PSA 14.7 upper so the rifle runs like a top. Now I want to make sure it stays where its at. Is just high temp loc tite on the set screws enough to keep the gas block in place or is dimpling the barrel a must? Also, has any one had problems with their low profile gas blocks moving out of place? Thanks Wanna kill these ads? We can help!
