JOSHUA, member, from TX, United States, asked on January 04, 2025

Will this fit a supressor with 1.375 outer diameter

Manufacturer Answer
A
Answered by Breek Arms, Manufacturer from MN, United States, on January 10, 2025

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.

Jed, member, from SC, United States, asked on July 21, 2022

Will this work with an adams arms low profile 300 blk piston kit?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on August 03, 2022

The Breek Arms RG2-S AR-15 MLOK Handguard has an internal diameter of 1.35". So it will most likely not work with the Adams Arms Low Profile Piston Kit. However, I recommend you measure how much clearance you need based on the measurements of the piston kit install on your rifle.
