Most Helpful Positive Review Excellent Rail
A tremendous accessory for the Sig P556. I also recommend Samson's sights. You may want to have a couple of extra screws sent from Samson, as they are a bugger to get out after you have installed them with blue locktite. Overall, you can't go wrong with this rail. Pros: Rock Solid Cons: None
Most Helpful Negative Review Wish it wasn't broken
Really wished it wasn't cross threaded when I revived it now waiting for Samson to fix it and hoping the mail doesn't lose it! Pros: Sturdy and build good Cons: Cross threaded when I revived it

This should have been standard on SIG 556

Easy to install. Great look. I like that it used the bayonet lug for mounting. gives additional strength. The new rali extended further back than the original and touched the portion of the lower just in front of the butt stock folder. May not be a problem, but I noted that this made the rear receiver pin hard to insert. You could also see a gap between the upper and lower receiver. This binding bothers me so I will file off a very thin amount of the lower receiver where the rail extended. The bare metal will be hidden when the upper is pinned in place. I suspect that if I do not file the material it will eventually wear the surface finish off anyway. Samson could remedy this by cupping the underside of the rail where it extends over the lower portion of the receiver. Other than this one item The fit and finish is excellent. I like this design better that the Troy rails because you get to keep the existing front sight or replace with a folder. The Troy rail uses the SIG front dovetail to mount secure the rail. Therefore you cannot keep the original sight.
Pros: Looks great, Easy installation, Well Made
Cons: The read of the rail touches the lower and required a samll aount of filling for clearance
Would recommend: Yes
