I love Yankee Hill
I'm a big fan of Y.H. gas blocks. They always fit for me and always function without a hic-up. I prefer their clamp ones more but for under a free float this one fits great and gives more clearance with out contacting the guard. I've never seen any bad wear on them after heavy use. I really like their clamp ons with folding sights but they just don't always go with a build. They are steel and not aluminium which is the biggest plus. Aluminum may be lighter but wear badly on heavy use.
