Handguard Adapters

Frontier Tactical™ creates innovative solutions for your AR. Our Handguard Adapters replace the traditional handguard cap and enable you to bypass the gas block with two piece drop in rails or handguards. Run the handguard or rail length you desire. With our Handguard Adapter, your handguard or rail is no longer determined by the barrel shoulder. An ideal choice for those looking for a rugged, battle rifle with longer rail or handguard options. Confidently mount your backup sight to your rail for longer sight radius, without point of aim (POA) change that occurs with free float guards, rails and tubes.

By using handguards instead of free floated rails, your hands are protected by heat shields; enabling combat firing of multiple magazines without wearing gloves or “calling a timeout”. The Handguard Adapter securely mounts your handguards and rails, eliminating flex or rattle created by traditional handguard caps and free float applications. Our Handguard Adapters are made in Round or Triangle styles; both styles are available in .750″ or .875″ I.D. Made in the U.S.A.

We personally believe that by manufacturing high quality products any need for guarantees or warranties become largely unnecessary. It is our intent to prove that we appreciate your investment in our product. To that end, we diligently strive to provide you with solid value for your trust in us at Frontier Tactical™.

Our Handguard Adapters have been designed to accept most commonly available rail systems and hand-guard assemblies. It is made from high strength aluminum for durability and lighter overall weight.
