Best sig 556 rail - Troy SIG 556 BattleRail (Rifle)

I have two Sig 556's. I was forced to use the more expensive Samson rail on one because it's a four hole model. That rail took a good deal of fitting in the front where the two sections of the rail join. I had to elongate the holes so that the top section did't bend downward causing the top of the rail to curve. If I had known how much better the Troy rail was, I would have altered the Sig to accept it. Two of the holes would have matched up so it wouldn't have been that bad.
The Troy rail I mounted on my 556R seems much stiffer, and it attached in minutes. I didn't have to apply heat to break the loctite, and I used the original screws on three of the holes. I can also remove the gas tube with the rail in place. You can't with the Samson rail.
I got a great price on the rail from Opticsplanet.com, and the free shipping really made it a bargain.
