SEEKINS SELECT ADJ GAS BLOCK .750

Description

The Seekins Precision Select is built for shooters who need genuine on-the-fly gas adjustment without giving up a repeatable starting point — the kind of requirement that comes up when running a rifle both suppressed and unsuppressed in the field. Most adjustable gas blocks force a trade-off: you can tune the system, but returning to a known setting after changing configurations is guesswork. The Select’s patent-pending design solves that by allowing near-infinite initial adjustment while preserving that setting as a reference, so switching between different running conditions doesn’t mean starting the tuning process over from scratch.

The block is machined from steel and finished in Melonite, which is a ferritic nitrocarburizing treatment rather than a surface coating. Because Melonite penetrates the steel rather than sitting on top of it, it doesn’t add appreciable dimension to the bore, and it produces a hard, corrosion-resistant surface that holds up to the heat and carbon exposure inherent to the gas port area. The .750-inch bore diameter fits the barrel profile most commonly found on mid-length and carbine AR-pattern builds, and the block is compatible with both AR-15 and AR-10/LR-308 platforms. Country of origin is the United States.

If your rifle runs inconsistently between suppressed and standard configurations — cycling too hard in one and short-stroking in the other — a block that lets you dial in separate settings and return to them reliably is worth the investment. The Select is a practical solution to a real operational problem, not a range accessory.
