Ordered as an add-on to previously purchased handguard. Went on easily, perfect fit and well-made.

This rail is light, strong, and looks great. The Gator grip is beyond what I anticipated. As far as the rail itself is concerned it is a clear 5-star winner. Unfortunately, it does not work as well as I had hoped with the Osprey gas piston system. When you slide the rail over the barrel nut adapter it pinches at the top making it difficult for the piston to slide, resulting in inconsistent cycling. I believe the problem will easily be solved with a quick pass of the Dremmel. Other than that one concern, I can't say enough good things about this product. It is perfect for my new found appreciation for light and clutter free builds. If I were using it for a typical gas impingement system it would be a clear 5+ star rating without hesitation.
