Bolt-On, 1-Stamp Upper for AR-15s

The KGM Integrally Suppressd Upper Receiver Group (ISURG) is purpose-built for 100% suppressed shooting, excelling in heavy-firing schedules, accuracy, repeatability, and sound suppression.

With efficient gas management, it enhances precision by redirecting gas away from the bullet’s flight path, eliminating over-gassing, and reducing toxic gases through its Integrated Gas Flow (IGF) design. The gas system is tuned for suppressed shooting, ensuring reliable function with various ammunition types. 

The suppressor with integrated gas block is pinned to an 11.5” barrel to achieve a 16.7” overall length barrel, balancing compactness with legal compliance. This upper receiver group is compatible with any AR-15 lower receiver group, the ISURG is out of the box ready with a full-auto BCG, charging handle and Back-Up Iron Sights (BUIS).
