NightStalker Posted January 15, 2022 Report Share Posted January 15, 2022 Question is there a difference in the gas block for an AR10 and AR15? I don’t think there is but want to ask Quote Link to comment Share on other sites More sharing options...
98Z5V Posted January 15, 2022 Report Share Posted January 15, 2022 The only difference is in the bore size of the gas block, for the gas block journal size. There's some weird ones out there now, with custom shiit, but the common ones are 0.625", 0.750", 0.875" (there's a pattern there, 0.125" apart), and then there's the 0.936". Gas blocks are gas blocks. Doesn't matter what AR they go onto. Depends on the barrel maker. Gas TUBES between large frame and small frame ARs SHOULD be different, because of height-over-bore between the two platforms. Different bends between the two, because of height-over-bore. Problem is, alot of barrel makers spec out an AR15 gas tube length for a Large Frame AR... it's not a huge deal, but it's still a deal, to deal with... Check this pic - it should be obvious...

NightStalker Posted May 7, 2022 Author Report Share Posted May 7, 2022 (edited) I found a mid length 12 in gas tube on CDNN for little over just under $7, Hoping this one is good to go https://www.cdnnsports.com/ar-308-gas-tube-midlength-bushmaster.html Edited May 7, 2022 by NightStalker Quote Link to comment Share on other sites More sharing options...

It's also not an Armalite AR-10 Carbine gas tube length. Quote Link to comment Share on other sites More sharing options...

AR15 Rifle gas tubes are 15.25" long. Here's what the bend to the barrel difference is, between AR15 and AR-10 gas tubes.
