Low profile gas block - Faxon Firearms Ultra Low-Profile Gas Block

As always when purchasing a Faxon product you can be assured of getting the best quality and at a good price. Out of all the reviews I have read about any Faxon product I have only came across one stupid comment as how their gas block was to small and didn't fit or how the ( brass was scratched on the extension of their barrel ) LAMO since when was brass ever used on a barrel extension and also i have used nothing but Faxon gas blocks and the fit has always been perfect so evidently the guy didn't order the correct size or as the comment about the barrel extension both are idiot's.
