Do you have a list of low profile gas blocks that will clear the evolution rails?

I am looking at the Daniel Defense clamp on. .750

Our gas block works great with all of our rails.

Thats cool, but I dont want to dimple my barrel.  So its either clamp on or have someone pin it.

You shouldn't need to dimple the barrel.  There are 4 set screws that hold it tight.  Two on the bottom and one on each side at a 45 degree angle.  They are very solid.  However I can tell you that the Evolution rail has an inside diameter if 1.56" and that DD LP GB should work just fine.  I would double check the dimensions of the gas block though.

Thanks,
