Rainier Arms has teamed with Samson Mfg to create a lighter weight "Evolution Series" rail. The tubular style of rail has become increasingly popular as civilian and LE shooters have decided the extra weight of a full quad rail isn't always needed, especially when you can just drop in rail sections where you want and still have the functionality of a quad rail. With a given weight of 11 ounces including the heatsink that installs over the barrel nut, this is one of the lighter rails we've seen. The top of the rail system is a full-length 1913 spec rail, and Rainier Arms includes two different drop-in rail sections, which let you throw on a light and VFG if you choose. Additional rail sections are available.
Installation of the rail is simple, but you need to remember that the heatsink pieces need to be installed as shown in the pictures below. Chop off the Delta ring cap, and remove the spring, then push the heatsink pieces into place. Note the half-circle portion goes on the bottom, and the full circle goes on the top next to the gas tube. If you try it the wrong way, you are only going to get frustrated as the tube won't slide over them. After you slide the rail in place, tighten the two screws, and you are done.
At $175, this full-length rail is worth checking out, especially if you are looking to slim down your blaster. Click the picture to check out the product specs and a video.
