Questions & Answers
Will this fit a supressor with 1.375 outer diameter Manufacturer Answer

No, the ID of the handguard is 1.375 as well. And even if there was a small amount of room you would still have to account for flexing, so keep that in mind as well.

Best 15 inch handguard on the market by Jesse, Verified Owner, April 27, 2023
I was looking for a 15 inch Handguard to add to my 16 inch barrel and I eventually found this Breek arms Handguard. Receiving this in the mail, I was amazed that this Handguard was being sold for under $150. The finish and the fitment alone are top t...

Sturdy and comfortable grip for your SBR by dubyam, Verified Owner, October 20, 2023
Picked up the 9.7" version for an SBR upper build that is a 10.5" 300BLK setup. Handguard is nicely finished, heavy enough to be sturdy, and comfortable in the hand. Seems like it's built well enough to be durable in the long-term, but I've owned i...

Breek Arms RGS2 Handguard by johnchip, Verified Owner, February 9, 2025
I bought the 9.7" and 11.7" versions of the Breek Arms RGS2 Handguard. They are really easy to install - no timing on the barrel nut and the wedge lock system is great. It's a nice firm lock up. The 9.7" was for a 11.5" upper build and the 11.7" was ...

really good for the price by c, Verified Owner, February 4, 2023
I haven't found a better value in a handguard anywhere. It's not super heavy or super light, it's just practical and purpose built. The finish scratches pretty easily so it will look right at home under a truck seat and you won't feel too bad the fir...

6.7 is a perfect fit for 7.5 inch SBR by Flex Crush, March 19, 2023
Perfect length for attachment of a direct thread suppressor or a muzzle mount adapter. Good finish, mounted no problems. I wanted to be able to get shims on and a wrench around a GP5 suppressor and this fits fine

Beautiful handguard! by Eric, Verified Owner, April 28, 2022
I bought the 6.7” handguard for a 7.5” 300 blackout pistol build. I had a hard time finding a high end handguard for the billet upper I used. Most premium handguards have anti-rotation tabs that only work with mil spec upper receivers. This handguard...

Product Info for Breek Arms AR-15 RG2-S MLOK Handguard

Breek Arms' mission is to provide quality parts at competitive prices. Our newly developed RG2-S (Rugged Rail Mod2) Handguard line up is an evolution from our previous lineup. Our Patent Pending locking mechanism uses a wedge block system that puts equal pressure all the way around the barrel nut. This gives you better harmonics and a much stronger mounting solution especially when you're putting pressure on the end using a bipod or sling.image

The Newly Released RG2 handguards were developed specifically for suppressor builds, each length is designed to fit common barrel length and leave room for all types of quick attach suppressor mounting solutions. The skeletonized design shaves as much weight as posssible without sacrificing the integrity of the handguard. All edges are chamfered, blasted, then Type 3 Hardcoat anodized for a smooth feel.
