No, not the 'goofy "high top" setup' but rather the "high profile" that was standard on DPMS rifles until they came out with the "low profile" rail.
I've been looking at the MI guards, including this 15" M-Lok version:
https://www.midwestindustriesinc.com/product-p/mi-308ss15-dhm.htmHave fond some keymod guards in the $147 to $165 range but prefer the M-lok. Don't know it I prefer it enough to pay a $50 premium.
Have also found some 16.5" and a 17" guard. Might consider them if I go with a 20" barrel.
