J P Enterprises Ar-15 2-Pc Detent Gas Block Low Profile .750 Steel Black
$113.95
The JP Enterprises AR-15 2-Piece Detent Gas Block is a low-profile adjustable gas block built for shooters who need precise tuning without the headaches of traditional setups. Sized for .750" barrels, this steel gas block pairs a click-adjustable detent system with a split-yoke design that makes installation straightforward—even on barrels with pin-and-weld muzzle devices where space and access are tight. Whether you're building a precision rifle, tuning a suppressed upper, or dialing in a piston gun, this two-piece design simplifies the job while keeping your gas settings locked in place.
The detent mechanism is where this block earns its keep. Six clicks per full rotation of the gas screw give you the fine control you need to find the sweet spot for reliable cycling and minimal recoil, without the guesswork of friction-fit adjustments. Once you've found your setting, the detent holds it secure—no more mystery adjustments or lost gas screws mid-range trip. All the detent components stay internally retained, so there's nothing loose to drop in the grass or gravel.
Installation is less of a chore than many gas blocks. The split-yoke design means you can fit this block onto your barrel without fighting alignment or wrestling with tight clearances under your handguard. Side-mounted gas adjustment keeps the port accessible even after your build is complete, so you can fine-tune on the fly if needed. The low-profile footprint works underneath most modern handguards on the market, making it a practical choice for both duty-focused builds and precision rifles.

Frequently Asked Questions
Will this gas block work with pin-and-weld barrel assemblies?
Yes. The two-piece split-yoke design is specifically intended to simplify installation even on barrels with pin-and-weld muzzle devices, where traditional single-piece blocks can be awkward or impossible to fit.
How fine can I tune the gas adjustment?
The click-adjustable detent system provides six clicks per full rotation of the gas screw, giving you precise incremental adjustments to dial in the exact gas flow your rifle needs for reliable cycling and minimal recoil.
What happens to the gas screw and detent parts—can they get lost?
No. All detent components are internally retained in the block itself, so there are no loose parts to drop during assembly or maintenance.
Is this gas block compatible with most AR-15 handguards?
The low-profile design is intended to mount underneath many handguard models on the market, though fit varies by handguard model. We recommend verifying clearance with your specific handguard before purchase.
