Drop in replacement for the Sig 556R

by RevEsteban, from United States, CA Written on February 8, 2015
I wanted a quad rail for my Sig 556R but was a little reluctant to try the Troy rail because of mixed online messages of its compatibility with the Sig 556R. Once I read the instructions, I was able to securely install it on the rifle within a half hour. It is stable and secure. Just the thing I was looking for....

Troy SIG 556 BattleRail

by Jim, from United States, PA Written on December 24, 2014
Great product. Was easy to install and fit as expected from a Troy product. It made the rifle more flexable with the added rails. I can now add a slanted forearm and a bipod. It is a good after market product to add to the SIG 556 rifle...

Best SIG 556 Rail

by Rob14505, from United States, FL Written on September 5, 2014
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....

Sig 556 replacement rail

by Legacy Reviewer, Verified Owner from United States, PA Written on February 16, 2013
This rail is a MUST for the sig 556. Easy to install, it replaces the factory plastic with a beautifully machined metal rail. Only thing is, you need to take the front sight off- so buy another one. Well worth it though....
