Questions & Answers
Will the anti-rotation fins fit into the anti-rotation slots on Cry Havoc’s QRB barrel plate adapter? Expert Answer

The Midwest Industries SP Series AR-15 M-LOK Handguard might work with the Cry Havocs QRB Barrel Plat Adapter. From what information I could find the QRB Barrel Plat Adapter is compatible with free float handguards with a width of 2.0". The outside diameter of the Midwest Industries SP Series AR-15 M-LOK Handguard is 2.0" so it should work but I recommend contacting Cry Havoc to confirm compatibility.

What size torque wrench will connect to the barrel wrench? 1/2? 3/8? Etc.. Expert Answer

The manufacturer doesn't specify what torque wrench size the barrel wrench is compatible with, so I recommend contacting the manufacturer to determine compatibility.

Cool Handguard. by Le, Verified Owner, May 23, 2025
It is easy to install, fits around my suppressor (OCL polonium 30). I recommend. Only downside is that larger OD supressors wont allow you to use the M-lok. The two inches where the M-lok goes over the suppressor has no attachments

Equal to Geissele and BCM by Broken Jarhead, Verified Owner, July 26, 2022
I have all the brands, and while Geissele and BCM have a more secure side mount, MI is equally sturdy and has great quality. It's fat since it can fit a suppressor, but it still handles perfectly with a angled foregrip and C-clamp hold.

Great 18" hand guard at a great price! All others I was looking at were only 15" and this one just fits so well. Came with all the xtra tools needed to attach to a build. 10/10 would recommend! Plus it shipped from Midwest.
