I got the rail in the set from Chris. http://www.centralfloridafirearms.com/product/cerakoted-fde-ar15-receiver-set/ I had thought about a shorter rail but for the price of the set figured I could sell the rail if I didn't like it, that's not happening though, I like it! Only downside is now I have to invest in keymod gear for it. Went with the regular SLR adjustable, titanium was too pricey and shiny for my taste, plus I'd hate to compete with breastguy for most anal lightweight parts buyer ;-) Pinned a standard flash hider on the 14.7 inch barrel, the comp I had was just a hair short of the 16 needed, kinda glad I went that way now, trading the minimal recoil reduction away is balanced by the lack of concussion felt. I think I'll yank the buffer weights tonight and hope for a decent day to test fire, range is pretty well snowed in right now.........
