Schwansonite Posted April 25, 2011 Report Share Posted April 25, 2011 Where did you all get a low profile gas block for a free float quad rail that is compatible with a 308? My barrel diameter is .750 but I heard that the gas systems for a Ar-15 and Ar-10 are different? Quote Link to comment Share on other sites More sharing options...
imschur Posted April 26, 2011 Report Share Posted April 26, 2011 Correct terminology may be causing you trouble. Your referring to the AR-10 in the DPMS LR-308 section. Only the Armalite is an AR-10. The DPMS LR-308 while similar looking is a different weapon. Which are you asking about? Im not well versed on the AR-10 gas system but and non SASS DPMS can use any milspec gas block providing you choose the block with a bore to match your barrel. There is another wrinkle with DPMS. The current upper receivers have a picatinny that's higher above the bore than similar weapons. A front sight mounted on a non DPMS railed gas block might not have sufficient elevation adjustment.Disclaimer: Im posting through severe allergies and mental fog Quote Link to comment Share on other sites More sharing options...
Schwansonite Posted April 26, 2011 Author Report Share Posted April 26, 2011 I'm sorry, I meant the Lr-308 AP4. I'm trying to find a low profile gas block that I can use. I'm about to buy the fulton armory liberator 12 inch free float but I have a carbine dpms Quote Link to comment Share on other sites More sharing options...
imschur Posted April 26, 2011 Report Share Posted April 26, 2011 ok keep in mind the Fulton Armory needs a special wrench which they don't sell. You need to buy a spanner wrench and modify it. We have a thread someplace on it here. Also go to the bottom of the home page for info http://308ar.com/ Quote Link to comment Share on other sites More sharing options...
