Handguards and Rails from Justrails.com



Your #1 Handguard and Picatinny Rail Store

One of the most important and personal decisions for customizing your AR-15 or AR-10, is the handguard or fore rail.  Most builds come set up with plastic drop in handguards, with picatinny rails on the top only.  


A super simple upgrade, is to go with an AR-15 Drop in or AR-10 Aluminum Drop In Quad Rail Handguard. You then have the extra picatinny rails, on the sides and bottom, for adding important quality aftermarket parts and accessories for your firearm.  Such as laser sights or a fore grip and bipod set up.


A more common upgrade, is to go with a Quality Aluminum Free Float Handguard or Rail.  This allows you more flexibility to go with any length of fore rail you prefer.  Available from 4.2" up to 19.5" in length, with either Keymod slots, M-LOK slots or even more picatinny rails.  Allowing you to add tons of available parts and accessories, available from the aftermarket.  Justrails.com is your #1 Online Source for Aftermarket Handguards, Rails, and much more...


We also carry a large stock of Stainless Steel Gas Tubes, Nitride Coated Gas Tubes and Low Profile Micro Gas Blocks for you AR.  We have them available in standard or adjustable gas blocks, and in the most common barrel diameters.  Made to fit the insides our AR-15 free float and AR-10 free float handguards, for a perfect addition with your handguard.
