I just ordered a Doublestar gas block with top picitiny rail for my BM Carbon 15 Superlight ORC. I read after i ordered it that there are two diffferent types of gas blocks (as far as how they mount to the barrel). I want to cancel the order before it ships if its the wrong type. Doesanyone know if this gas block will work with the BM Superlight (.625 barrel). Or which would work? You're a lifesaver if you can help!
