The TROY .875 Low Profile Gas Block is built for AR .308 platforms that require a .875-inch gas block seat, commonly found on bull-barrel rifles. Machined from 4140 pre‑hardened steel and finished to MIL‑STD manganese phosphate standards, it provides a compact, serviceable footprint while maintaining robust construction. The low-profile form helps clear handguards and sighting systems while keeping gas system alignment simple for standard gas tubes.

With straightforward engineering and durable materials, this gas block suits precision-oriented builds and heavy-use service rifles where a low-profile, reliably machined component is required. Its clean profile and proven materials make it a practical choice for AR .308 assemblies that specify a .875-inch gas block seat.
