CQB 11.5″ .223W One-Stamp Upper (GP-5™ Silencer)

Description

Griffin suppressed uppers ship from the factory with the suppressor pinned and welded to the barrel to achieve a non NFA (non SBR) regulated overall barrel length of +16″ per ATF regulations.

This MK1 CQB 11.5″ .223W One-Stamp Upper comes from the factory with a GP5™ Suppressor pinned and welded to the barrel, requiring a tax stamp for the suppressor only – hence the “One-Stamp” designation in conjunction with permanent attachment to a barrel typical in use on SBR’s. This upper makes an ideal home defense firearm, and ensures end user hearing protection. GP™ suppressors offer sub OSHA 140DB impulse risk limit, sound performance at minimal weight with high durability. The latest generation of GP™ suppressors are tubeless in construction, yielding lighter weights than previous GP™ suppressor generations, while maintaining their full-auto durability rating with no minimum barrel length restrictions. This latest generation GP5™ Suppressor incorporates a flash-hiding end cap design borrowed from the popular EXPLORR® family of suppressors.

One-Stamp uppers feature Griffin’s Suppressor-Ready Rail system which overhangs the suppressor, creating a unique, integrally-suppressed look, with more handguard length for muzzle control. The complete uppers are ready for use right out of the box, and include Griffin’s Enhanced Mil-Spec BCG, SN-ACH™ 15 Charging Handle, M2™ flip-up Iron Sights, PRIMO Gas Block™, and 4-piece Rail-Shield™ furniture kit. This upper features Griffin’s 11.5″ HEDP™ Barrel made from nitrided 416R Stainless Steel which provides incredible accuracy with maximum lifespan. TRUE-BORE™ concentric suppressor-grade threads provide an optimized interface for pinning and welding the GP5™ Suppressor providing guaranteed concentric suppressor alignment.

Griffin’s One-Stamp uppers offer premium features and reliability to each user, with the ease and simplicity of having a one-stamp build without the need for multiple tax stamps.
