Knight's armament ras m4 quad rail - Knight's Armament M4 Carbine RAS Forehand Assembly with Three 11-Rib Panels

First off I am not a free float handguard guy I don't like spending extra cash on rails that you have to put on the thing when they should already be on there thats just my opinion. Quad rails might be old school but they work just fine. I was looking for a good quad to replace my magpul plastic thing. I knew I wanted this one have wanted it for a long time but could never seem to finder any one who had them in stock. Came to optic to see what they have that was similar was looking threw and I saw this in stock I was like yes!!. The quad was a little pricey but I just got it today and put it on the 6920 and it is fantastic fit on my rifle great no wobble was not hard to put on fallow the direction that come with it you be ok. The covers that came with it are metal I thought they would be rubber but they are not,its no big deal is comfortable. It don't weigh down the front of the rifle at all. And optic they are awesome as well it said it would ship out with in 1 to 4 months I was like what than the next day boom has been shipped, yes!! Lol thanks for an awesome product optic.
