Quarter Circle 10 is proud to offer our compact handguard system, designed from the beginning to be the perfect pairing for our pistol caliber barrels and any other short-barreled AR platform weapons.

Designed and manufactured in-house by QC10’s design and engineering team, this is the premium-quality handguard and attachment system for the accessories and tools you want on your firearm. Our lightweight, free float design makes the most of the short barreled weapon you’ve chosen.

The QC10 handguard is made to end just short of the shoulder of the barrel threading (see chart below for specific lengths.)
