Questions & Answers
does this include the barrel nut? Expert Answer

The Centurion Arms C4 Rail Handguard does not come with a barrel nut.

by Hunter, Gear Expert, December 19, 2022
Would this fit on and dpms .308 AR? Expert Answer

The manufacturer doesn't specify if the Centurion Arms C4 Rail Handguard will fit DPMS Pattern AR10's. I recommend contacting the manufacturer for that information. Here are some options for handguards for a DPMS Pattern rifle.

Heavy Duty Free Float by Jordan W, Verified Owner, November 2, 2025
If you want a heavy duty free float quad rail, you really can't find better. I put this on an 11.5 upper with surefire rc3 and comp m4. Overall package is 9lb loaded. Heavy, but rock solid. Weight was not a primary concern on this build. You need to...

Extended Carbine Handguard by JT, July 9, 2018
This hand guard is great if you want something strong, looks excellent, and allows the use of a little more space to the front end of the barrel while retaining the fixed front sight post. A free float design without changing everything to have it.

Excellent! by D, January 6, 2018
Very high quality and easy to install. The instructions don't mention that the front handguard retainer needs to be removed but that's a pretty minor complaint. If you're looking for a little extra rail space while retaining your fsp, this is the w...
