DSC Sight Block Barrel - XC Edition
Couldn't load pickup availability
The DSC Sight Block Barrel opens the door for XC owners to finally run their pistol in both duty roles and competition divisions where ported barrels are restricted. By removing the factory porting while retaining the benefits of a sight block, this barrel keeps the front end planted, stabilizes recoil, and makes the XC versatile for more than just the range.
Key Features:
-
Duty & Competition Ready – Built for XC owners who previously couldn’t use their pistol in service or divisions that ban porting.
-
Exclusive XC Fit – Designed specifically for the Staccato XC platform.
-
Two-Piece Construction – Barrel and sight block are permanently bonded using an untraditional threading system, making the sight block only compatible with its matched barrel.
-
Sight Block Design (No Porting) – Adds weight and stability without gas compensation.
-
Front Sight Optional – Standard design comes without front sight, front sight available as add on
-
Porting Service Optional – Standard design is sight block only, no port - MR1 Port available as add on
-
Premium Finish Options – Stainless steel standard; DLC, PVD, TiN, or Hard Chrome upgrades available for both barrel and sight block (adds 5–7 weeks).
Fit Options:
-
DSC Fit – You send in your XC slide or build for DSC to hand fit the barrel to your build’s specific tolerances.
