Questions & Answers
will this tuck in under an aero precision r one handguard? Expert Answer

The internal diameter of the Aero Precision AR15 Atlas R-One M-LOK Handguard is 1.3". The outside diameter of the Kaw Valley Precision MACH 3 Modular Linear Compensator is 1.28". So it will most likely not fit under that handguard.

Does this item COME WITH a thread adapter of any size? Or is that sold separately increasing the actual price by $20? I need 5/8x24 Expert Answer

The Kaw Valley Precision MACH 3 Modular Linear Compensator does not come with a thread adapter. The 5/8x24 thread adapter can be found at the link below.

Very cool addition by Ethan, Verified Owner, October 30, 2025
While it doesn't make my gun any quieter, it does help to make my AR's muzzle brake considerably less rude by directing the blast downrange. And it looks like a suppressor, so it adds to the cool factor.

Really Nice Quality by R.R., Verified Owner, December 9, 2022
Good Compensator. It's able to be extended or reduced whenever you want. Thread adapters are a little pricey compared to the comp itself, but it's still a good value when compared to other options. It's a great option when you want a tucked look insi...

Love these by Gregory, Verified Owner, February 29, 2024
These work great as linear comps. They are modular, which allows for different lengths. Also, they fit inside most handguards. Very good quality also. A little pricey though since the barrel adapter is another $20.

Be aware you'll have to buy a a muzzle thread adapter separately. I deducted a star for that. I realize the assembly picture does not show a muzzle thread adapter but I bought the variant labeled "1/2-28" and this does not include any threads that pi...

Really nice linear compensator by Michael High, Verified Owner, April 17, 2024
I purchased this for a 7.5 inch AR pistol. The shorter the barrel, the louder the blast and concussion. This should put all that a bit further out. The machining was done exceptionally well; tight thread with zero wiggle. The only negative to thi...

Product Info for Kaw Valley Precision MACH 3 Modular Linear Compensator Body

The KVP MACH Modular Linear Comp is a Patent Pending linear compensator system that is completely user configurable! If you've struggled to find a comp the correct length for the perfect "tuck," configure ytheir own! By utilizing 1-1/8x28 TPI internal threads, the MACH Modular Linear Comp can utilize common suppressor attachments, such as a SilencerCo 3-Lug Mount, SilencerCo Direct thread mounts, etc. KVP has opened up a level of modularity that has never before been offered in the Linear Comp market. The Mach Comps allow end users to run any length comp they want, including extra long configurations acting as a placeholder for a suppressor awaiting a Form 4 approval. Each component is machined from 6061-T651 Aluminum and hard coat anodized for wear protection. The MACH system utilizes a 1-1/4 hexagonal wrench flat configuration for easy installation with a standard open end or adjustable wrench. For permanent configurations of a MACH Modular Linear Comp, Red Locktite (or similar) thread locker should be considered. If future re-configure of the comp is desired, anti-seize on the mating threads is recommended.image

Note: This kit does NOT include a thread adapter.
