Scott G Posted August 24, 2014 Report Share Posted August 24, 2014 I've seen several threads saying there is no difference in the .223 gas blocks and the .308. However I just got off the Precision Reflex website and they have two different adjustable gas blocks for barrels with .875" OD, which is what I need. They are out of the one they advertise for .308 (item 03-875-02GT) but they have "ample stock" for the one made for the AR-15 (item 05-875-02GT). Does anyone know what the difference in the two would be? They appear to be identical with the exception of one supposedly made for the AR-15 and the other for .308.
