Quarter Circle 10 is proud to offer shooters the QC10 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 you may need to outfit.

Our handguard is a lightweight, free float design that makes the most of the short barreled weapon you’ve chosen. Designed and manufactured in-house by QC10’s brilliant design and engineering team, this is a premium-quality handguard and attachment system for the accessories and tools you want on your firearm. CNC milled from 6061 aluminum, our system is available with the VLTOR Keymod attachment systems on 7 faces, and a solid 1913 Picatinny rail at the 12 o’clock position. Lightweight, utilitarian, and engineered with the distinctive QC10 aesthetic, this handguard is the perfect way to finish your pistol caliber build. Our handguard features:

  • Free float design
  • Secures directly to barrel nut
  • Continuous top Picatinny rail
  • Compatible with low profile gas blocks
  • 1.56″ Inner diameter fits many suppressors and muzzle devices
  • Rail aligns with Pistol MUR upper receiver rail

Whether for home-defense, law enforcement, competition, or plinking, Quarter Circle 10 has you covered, with our philosophy of Made For- Not Modified. Each of our parts is engineered and manufactured with pistol-calibers in mind, rather than modified from rifle-caliber components as an afterthought. We’re Quarter Circle 10, the AR Pistol-Caliber brand.


**This product may not be compatible with side-charging upper receivers from Quarter Circle 10, American Spirit Arms, Gibbz, etc., or billet upper receivers, including the F-1 Firearms Skeletonized upper.
