As everyone knows there are a huge number of addons for the AR15 family of rifles. Some of these aftermarket parts are very good while others are best ignored. I recently found a new extended carbine rail system from Apex that’s well worth considering as a replacement for your current GI grip or traditional four rails.



At a weight of only 8.1 ounces with three extra rail attachments the weight is considerably less than the usual free float rail system. Most standard configurations have four full length rails which are seldom used in full and just add weight. They can also be pretty rough on your hands unless you add rail covers, which increase the bulk and size of the rails.

The Apex extended carbine system allows the AR15 owner to add assorted short rails to a greater number of locations than a standard system. Extra short rails of one inch to four inches can be placed in eight locations around the entire tube utilizing the milled slots. Most of us only need a flashlight mount and possibly a vertical grip. If you want to add additional items just add an appropriate size short rail in the location best served for that add on. The Apex rail system has the capacity to add four QD sling attachments; two on each side. If you use a single point sling no problem just leave them open for later use if needed.
The top rail is 7.5 inches long and mates perfectly with the receiver rail. The external diameter of the tube is 1.970 inches, which is much less than standard rail systems.

Apex has also solved the rough surface problem most rails have by milling a grip surface they call a Gator Grip. This gives the shooter a firm grip without being abrasive to the shooters hands.
