Upgrade your AR with a replacement handguard. If you have the original-style handguards, you know how difficult these are to replace. They also do not accept accessories. A Midwest Industries free-float handguard goes on and off with an Allen wrench. The handguard clamps to a replacement barrel nut, also available here. The Midwest Industries rail allows you to add tactical lights, tilted iron sights and so much more. The ports in the handguard let your barrel cool much faster compared to a traditional handguard.
The Midwest Industries M-Lok ports give you space for hundreds of configurations and accessories. The Midwest Industries drop-in quad rail gives you four times the space for adding accessories that attach to Picatinny rails. Put on a fast-detach bipod, a light and angled sights. A Midwest Industries quick-detach sling swivel lets you easily add or remove a sling for increased tactical carry ability.
