Breek Arms mission is to provide quality parts at competitive prices and the DELTA handguard lineup release is the next step. We’ve found the perfect formula between cost, quality, durability, aesthetics, and weight reduction for our newly developed AR15 handguards!

The Newly Released RNGR was developed specifically for suppressor builds, each length is designed to fit common barrel lengths and leave room for a suppressor. It also works well for short builds - coming in as short as 5.25 inches long it is the perfect handguard for any short barrel AR build. Though it is short, it still has room for 1 M-LOK slot on the bottom and 2 slots on each side. In addition, the other lengths provide multiple additional length options to suit your custom build.


For use on AR-15 & M4 variants (223, 556, & 300blk)

T6-6061 Type III Hard Coat Anodized Aluminum

Cutouts made to reduce weight and provide barrel ventilation

Magpul Licensed M-LOK Mounting System

Clamp on Barrel Nut System with spacer allows for a rock solid clamp, holding the handguard in place easily

Steel Barrel Nut is serrated for increased grip and made from high strength steel and coated for durability and longevity

    Awesome handguard!

    Posted by Jake Murphy on Apr 3rd 2020

    I purchased the 15.75" model and it fits my 16" perfectly! Lightweight and well made with a very nice finish. This is my 3rd Breek arms handguard, but it definitely won't be my last!

    Fit and finish is top notch. Easy install, solid mount. Lightweight and tough. The 15" version finished perfectly with my Strike Industries Sail Comp. I will be recommending friends and buying more parts from Breek Arms!
