What HK should have done from day one. - MCLMM

I am a HK416 nut. I absolutely love the platform. I have the SMR rail for the 10.4" upper and the 14.5" upper. I will be buying another 14.5" SMR rail next month for a 3rd upper of mine. With a SF 212 suppressor the fit is just perfect to give it that seamless look but with just the right amount of clearance needed for the can to clear. I have run a PVS-30 as well as LA-5's on these rails with absolutely no shift in the laser's POI when taking the rail on and off. That alone is worth the price paid.

They fit the hand perfectly, especially the 14.5" rail on the 14.5" 416 upper. I installed a factory AGR gas block on mine and professionally drilled a small hole to access that gas selector. It ended up being in a structurally sound part of the rail and worked out great giving me no worries that I may have weakened the rail.

***Now if I could talk the Geissele guys into doing a small run of Colt large pin MR556 triggers for those of us who bought SBR's back when Colt was the only factory game in town I would be golden (hint-hint).

Hope you guys enjoyed the Pecans from down in SC at Christmas and thanks for a great product line.

Just awesome - Dan

I took the plunge and bought a MR556 upper to put on a ar15 lower. Along with my MR556 upper I bought the Geissele MR556 trigger and loved the setup. However, I found the keymod rail that came with my MR556 was just way too thick and bulky looking. After researching and looking around for a while I figured I'd get the Geissele rail and realized that I should have done that from the get go. This rail looks slick and thin on a MR556 upper. I got the 14.5" black rail, and it looks similar to what a 13" rail would look on a 16" barrel. The rail is very skinny. I think the skinniest rail you can get for your MR556.

The rail comes with picatinny rail panels that you can attach anywhere along the rail. I only attached one picatinny rail to the side to attach a flash light.

Overall I am very pleased with this rail. My handling of the MR556 feels better and more natural than it did when I had the other rail. I personally love skinny rails and this fits the best from what I can tell. It appears MR556 rails are getting harder, and harder to come by and my advice is if you got a MR556 upper/rifle you should definitely consider purchasing one of these rails. You don't need to do anything special other than slip it on the barrel nut and you can even use the same barrel nut that came with your rifle if you feel like having a backup spare.
