Honest Review

by Yura K, from United States, WA Written on March 4, 2015
I bought the rail to give the gun a more "modern" look and feel. Accuracy, was said to improve after installing this rail, after reading online forums. Well, that was not at all the case. In my case, accuracy suffered about 50-75% loss with various ammunition. I tried accuracy tests using Sellier & Bellot, TulAmmo, Red Army Std, Winchester, PMC, PPU and, the infamous, Mil-Surp boxes. This gun is no tac-driver to begin with, but, thats not what it was designed for.

Any gun with this much rail space will be a cheese grater on the hands and sand bags. I installed the Surefire Rail Ladders on every exposed Picatinny and it complemented the rail perfectly. Im not sure what the cut out on the bottom forward end of the handguard is for, but, that still has some sharp corners that are still exposed. Still, its a well handling forend.

The install was really easy, and no gunsmith was required. I installed all fasteners using Loc-tite Green, as it is the ONLY thing that has kept ALL of my fasteners for EVER coming off, regardless of heat, or round count.

Disassembly of the complete weapon is no longer as easy as Sig designed it to be. The "Piston Tube" no longer comes out by 1/4 turn and pull out. There's a notch on top of the "Piston-Tube" that becomes trapped by the channel in the top of the handguard. Thus, requiring one to remove the Top portion of the handguard, along with any optics that might have been installed over the rail screws. Not a show stopper, as not everyone is that...

I really wanted to like it.

I chose the Samson over the Troy rail because of availability, big mistake. The rail is not standard 1913 mil spec size. Its slightly too large, which means accessories that clamp on to the rail fit, but plastic accessories like LaRue Index Clips and Magpul Angled Foregrips dont fit. I'm sent Samson email about it but have yet to hear back. Should I got the Troy.
Pros: Looks sexy
Cons: Limits what accessories you can use. ...
Would recommend: No
