MickB Posted July 6, 2013 Share Posted July 6, 2013 I'm looking for a low profile, steel gas block to go on a Criterion 0.750 barrel and am using a Samson Evolution rail. Do any of the clamp style gas blocks fit under the Samson rail? Mick Link to comment Share on other sites More sharing options...

Bryan 45 Posted July 6, 2013 Share Posted July 6, 2013 Samson makes a great low pro steel gas block. It attaches with set screws but there are three of them, and set at opposing angles. Link to comment Share on other sites More sharing options...

MickB Posted July 7, 2013 Author Share Posted July 7, 2013 The new style JP gas block? The old style would not fit... Mick I have JP under 15" Evolution. Link to comment Share on other sites More sharing options...
2mikes Posted July 8, 2013 Share Posted July 8, 2013 Old one fits there just fine. Link to comment Share on other sites More sharing options...
MickB Posted July 8, 2013 Author Share Posted July 8, 2013 Interesting. I will have to check mine again. Maybe I was putting the handguard on at a cocked angle? Do you have easy access to the adjustment screw through the handguard slots? Mick Old one fits there just fine. Link to comment Share on other sites More sharing options...
2mikes Posted July 10, 2013 Share Posted July 10, 2013 (edited) Yes, I was lucky for a change. Otherwise I would have just drilled a hole for it. The barrel is 20" HBAR. Edited July 10, 2013 by 2mikes Link to comment Share on other sites More sharing options...
MickB Posted July 12, 2013 Author Share Posted July 12, 2013 So, after checking again, the old style JP gas block does indeed fit. as the pictures above show. It would also be safe to assume that the new style JP adjustable gas block would also fit. Another gas block that fits well, for those not wanting adjustable gas, is the Daniel Defense clamp on low profile gas block. Mick Link to comment Share on other sites More sharing options...
