Owner gerhardt defense armament - Surefire M4 Rail Covers, Set Of 3 Z70

These are the best rail covers I have ever owned! They are soft rubber and look very unique and classy compare to plain polymer rail covers. They have a depression or valley in the center of each slot. This gives a great appearance. People don't know this but that line of concave little depressions on the top section of the picatinny rail on a rifle draws a line of sight like a pistol non-reflective slide sight line. It draws a line toward the front sight of your rifle for quick acquisition of the sight radius length! One of the best products surfire makes! Cons: I wish they came in OD Green, Grey, FDE , etc. like the New Ergo # 4010 Ergo 2 AR Grip Sure Grip pistol grip colors.
