RayGun19 Posted July 20, 2011 Report Share Posted July 20, 2011 So, I find that I'm in need of a new gas block for my AR10. I bought a set of Dueck Defense RTS and installed them on my AR10. With my ACOG it's a tack driver, but I couldn't get the sights to print at all. I did the old "look down the bore at a target and then check the sights" trick. The sights were WAY off. I couldn't believe this. A check of their site looked like they couldn't be used on an 7.62 platform. But The article I read showed Barry using them on one.An email to DD was responded to by Barry himself! He let me in on that Armalite has a lower bore height gas block rail than standard, and that compounded the problem with the sights being on a 45 degree angle.Sooooo, I need a new gas block. It's not really being used as a gas block anymore, just a mount for sights and the delta ring. So I'm looking for a light weight, well made gas block in .750 through bore. Rail mount on top, and maybe on the bottom, but it has to be clamp style. Any suggestions? Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted July 21, 2011 Report Share Posted July 21, 2011 PRI, JD Machine and MI all have a gas block the same height as the upper rail. Just make sure you get the .308 specific one. I have the PRI in 5.56 and 7.62, there's a sizable difference between the two. Quote Link to comment Share on other sites More sharing options...
