JP Adjustable Gas Block - .936 Gas Journal

The JP JPGS-8D is the large-bore, low-profile adjustable gas block built for heavy .936” barrels and modern handguards. The click-adjustable detent gives precise, repeatable gas control so you can smoothly recoil, cut blowback, and run clean with or without a suppressor. Lightweight 6061-T6 construction, a split yoke for easy installs, and side access adjustment make it a set-and-forget upgrade that actually stays set.
