Riflespeed Gas Controls are compatible with the vast majority of common handguards. There are a few known handguard models that may not have enough room to allow proper clearance around or above your Gas Control. This short list includes the models below. Please note that some of these can be made to work with very minor modifications and some, like the Atlas R1 will work with no changes in SOME rifle configurations. If your handguard has an inside diameter of approximately 1.3 inches and the traditional "inverted keyhole" shape of most handguards you'll likely have no fitment issues.
List of handguards with known or potential fitment issues:
- Smoke Composite carbon fiber handguard (some other cylindrical handguards will likely have similar issues. Offset models like the Apex have no issues)
- Daniel Defense RIS II (Can work in some configurations with modification to handguard)
- SOLGW M89 handguard (there is a small protrusion inside the top of the handguard extrusion for an anti-rotation pin that may cause clearance issues in some configurations)
- Aero Atlas R1 (works in configurations where the Gas Control is near the end of the handguard) Minor modification to handguard may be required.
- Aero Atlas S1 (the lowered center section causes fitment issues)
- **Some** PRI cylindrical handguards with fasteners that protrude inside the cylinder to retain the 12:00 picatinny rail. Customers report that others work fine.
- BLK LBL BIPOD AR15 - AR10 Handguard (Customers have told us that a newer version that is compatible with Gas Controls is in the works, but this has not been confirmed with BLK LBL)
- The Radian handguard requires a very small amount of metal to be removed inside the gas tube channel to clear the top of the Gas Control.

I wanted to confirm that your RS7533 would fit within an Aero M5 (308) Enhanced Gen 2 hand guard (AERO SKU: APPG308226). I cannot find a dimension diagram for this hand guard. I can only find the statement that Aero has 1.72" inside diameter.

Recently purchased a gas control and found that YHM Smooth Series Handguards are a “NO GO”….Very happy with the Gas Control and also YHM Products. Just need to pay more attention to the details when ordering…

LaRue LAT style rails will not fit over the gas block.

Will not fit LaRue LAT, and will contact top of rail on ALG EMR.

do you guys know if the riflespeed gastube/block fit under a radian handguard? Admin response: The Radian handguard requires a VERY small amount of material to be removed right above the Gas Control. The amount of material is roughly the same as the thickness of a couple sheets of paper. Our friends at DDM can do this for you if you’re not interested in DIY.

The gas block is not compatible with Zev wedge lock hand guards. These are similar to the SOLGW hand guards. Maybe this is obvious, maybe not. But, I didn’t know.

I want to confirm that the Timber Creek Outdoors Enforcer handguards WILL NOT fit the Riflespeed gas block. The handguard does install, but once secured it will contact the gas block and prevent adjustments. It's so close, yet will not work. If you want the gas block exposed I suppose it will be fine since a shorter handguard will fit past it, but it won't work properly if you want the gas block inside the handguard.

Will not fit the Daniel Defense RISII Quad Rail Handguard Admin response: The DD RIS III is an easy fit if you’re looking for a DD branded alternative.

YHM MR7 Handguard does NOT work with this gas block. I have the 12.25" M-Lok version of this handguard. The inner diameter of the handguard is a perfect circle, with the 12:00 postion of the handguard lacking a 'channel' for the upper part of the block to fit into. I would normally just remove material as I would love to use this gas block, but unfortunately I'd have to remove a ton of material, and doing so on the interior of a handguard would be a major pain. Admin response: The easiest way to do this is machine a small slot above the Gas Control through the top of the handguard. Our friends at DDM can do this for you. Alternately, we have a selection of compatible handguards available in the “Build Parts” category of our store here on RifleSpeed.com

Aero Precision Quantum handguards are not compatible with this gas system. The handguard interferes with the top of the gas block and won't install.

Does this fit in the DD RIS3? Admin response: Yes. You may need to remove the grenade launcher tabs inside the handguard on some configurations. This is how Daniel Defense installs Gas Controls under factory built RIS3-equipped carbines.

Does not fit Yankee Hill Diamond Handgaurd.
