Solid System, Quality Materials
I prefer this item in it's 1913 rail configuration from Centurion. It's well made, lightweight, and easy to install without removing your barrel nut and it's factory torque setting. I am able to use Knights rail covers on the bottom, but not on the sides (I was able to force them on the sides from the back, but they don't click in place without excessive force being used.) Highly recommended item.

Geat Quality Product
This product is extremely well made and very lightweight for a quad rail system. This 12" rail will fit perfectly behind a front sight gas block on a 20" barrel. It also incorporates very well placed lightning holes that make it both aesthetically pleasing and does not compromise the integrity of the rail system. It incorporates built in quick detach points in the front and rear of the 9 o clock and 3 o clock positioned rail. This allow the shooter to incorporate traditional and non traditional slings. The screw holes incorporate a new and innovating way of keeping the screws from backing out by having a spring that applies reverse tension on the screws. I highly recommend this product for anyone interested in a very well designed rail system for their weapon system. 5 out of 5 product

Great rail
Solid and lightweight considering all the mounting options. I prefer these quad rails over the new versions as with magpul/KAC style rail covers it puts a little bit more room between your hand and a hot barrel. Great product. Did I say it was solid. Its solid.

Easy install and quality fit and finish
Two-piece design made install incredibly smooth. Mounted to a standard barrel nut with four hex bolts and two more bolts near the muzzle end of the rail. Extremely rigid design and the fit and finish are exceptional. Any lightweight free-float rail will heat up quickly, but utilizing any standard Magpul or KAC rail covers counteracted any heat issues. The design is simple and the concept of a quad rail is proven. I prefer this design to newer keymod rails that require additional accessories to mount lights, grips, etc.

Nice rail
Great rail, went back and forth on all my options and chose this one. Light weight, nice finish, great fit. Though when tightening the rail to the barrel nut, tension caused paint to chip on the upper half of the rail. Careful how you install.

Not so impresed
Its a good rail, does its job. Easy instal, looks great. But it gets hot during rapid fire. Its touching the barrel nut and it conducts heat fast. You better wear gloves when using this product, or have some awsome rail gaurds.
