The Samson Evolution Series 9-EX” Rail stands out from the rest of the rails in the Samson offering for a few reasons. First, the tubular with slightly angular feel of the rail handles great and fits good in the hands of everyone I know. Secondly, the cutout for the rail allows for a folding gas block sight, fixed FSB or for an adjustable gas block similar to the offerings of Noveske Rifleworks or several other companies.

The aluminum rail is easy to install, and basic hand tools will get the job done. Cut off the Delta ring, and slap on the two part heat sinks and you are ready to slide the rail into place. Instructions from Samson MFG are available on just in case you get worried you may be doing something wrong.

If you are looking for a setup that isn't a clone of what everyone else has, you owe it to yourself to check this one out.
