Will this work on the YHM R9? Expert Answer

No. The Yankee Hill Machine R9 will be compatible with the YHM 3-Lug Mount and YHM Nielsen Booster Assembly. The Yankee Hill 2045 3-Lug Adapter Assembly can be found linked below:

What is the max OD of this device? Around the fat collar section? Expert Answer

The manufacturer does not state the OD of the Yankee Hill Machine Phantom 5.56 Q.D. Muzzle Brake 1/2x28. I recommend contacting the manufacturer for that information.

Suppressor Ready by Petok, August 9, 2017
Shot a few hundred rounds using this brake (alone and in combination with the YHM 30 cal blast deflector) and was very pleased. The ratchet works great and the brake design reduces recoil when used alone. Ready for that form 4 to come back.

Love yhm QD system by Md2k, Verified Owner, May 29, 2018
Yhm QD system is great....quick lockup and spring tension to hold it. This new brake is so much better looking and functional...the flash hiders are pretty...umm... Not appealing. I used one on my 556 and tried it on my m92 AK and I really liked it...

No I'm Suppressed by Reno Skip, Verified Owner, September 15, 2025
Shipped quick and fit perfectly. I wish YHM included this size with the can but that one will fit nicely on the .308
