"I actually love the rail it is very nice. However it does require a special crows foot wrench 1 3/16 to be precise. Ordered the Sunex wrench not too bad. Get said wrench and its two wide to fit in the channel to put the barrel nut on. Very frustrating, take it to the grinder and down size it. It would be nice if they would put ears on the back of rail to line up on the receiver, as fine tuning the rail with upper rail is very difficult and miniscule difference"
