Questions & Answers
Will this fit an Aero m4e1 upper? (Not the enhanced version) Expert Answer

Yes, the Radical Firearms M-LOK Hybrid Rail System will be compatible with your non-enhanced M4E1 upper receiver since it is designed to accept a standard AR15 barrel nut.

Will this fit a Huldra/Adams Arms Mark IV AR-15 piston driven system. The current hand guard on it is 9 inches long Expert Answer

Radical Firearms doesn't state if the Radical Firearms M-LOK Hybrid Rail System handguards are compatible with piston driven systems. I recommend contacting Radical Firearms to confirm compatibility.

No shims again with handguard by fdc1970, Verified Owner, April 23, 2022
I just received this MHR15 handguard again with no shims. The description says shims included! This barrel nut will never line up for the gas tube without the shims and the nut is way off being lined up 30-40lb torque. I can't install this! The mount...

Misleading by Ben Adler, Verified Owner, March 10, 2021
The picture shows there are holes at the back of the handguard to screw it in place, however I got mine and there were no screw holes. I ended up having to use a drill and drill my own holes, which didn’t work too bad. It was still very disappointing...
