JP Two-Piece Adjustable Gas Block with Detent, .750 Bore, Black Stainless, Ultra Low Profile
Ultra-minimized D2 Series low-profile .750 gas block in 416 stainless with exterior D2 detent nut (52-click sweep) for extremely fine gas control, improved dirt tolerance, and easy installation under tight handguards. Two-piece design fits pin-and-weld barrels.
JP Two-Piece Adjustable Gas Block with Detent, .750 Bore, Black Stainless, Ultra Low Profile
JPGS-11D2 is the .750 entry in our D2 Series: an ultra-minimized two-piece gas block engineered to sit under the slimmest hand guards while providing exceptionally fine, repeatable gas adjustment and robust tolerance to dirt and fouling. The D2 Series uses an externally mounted adjustment nut with a heavy-duty 5/32 drive and redesigned forward-facing geometry that avoids handguard interference and sheds carbon. With 52 clicks between fully closed and fully open, the D2 Series doubles the resolution of our prior detent blocks—ideal for short-barrel/high-pressure systems and SBRs.
