Sadlak Industries Ar-15 Low Profile Gas Block .750 Steel Phosphate
A properly sized gas block is foundation work on any AR-15 build, and the Sadlak Industries AR-15 low profile gas block in .750" steel phosphate gives you a precision-made component that works hard and stays out of sight. Sadlak has built a reputation for hands-on manufacturing—every bore is precision honed and critical dimensions are 100% inspected to guarantee consistency, and this low-profile model keeps your setup clean and streamlined, especially if you're running a free-float handguard or want maximum grip surface on a carbine-length barrel. The steel phosphate finish is durable field-ready wear, and the included setscrews mount securely to your barrel with straightforward, reliable clamping.
This .750" size fits a standard mid-length or rifle-length AR gas tube, and the low-profile design means it tucks underneath modern handguards without interference—no bulky gas block profile stealing real estate from your rail system. Whether you're building a precision rifle from parts or refreshing an existing upper, a quality gas block made in the USA with real attention to bore honing and dimensional accuracy removes one variable from your equation.
All hardware is included; no hunting for the right setscrews. If you've built ARs before, you know how much better it feels to work with parts that are actually honed and inspected rather than cast and hope-for. Sadlak's commitment to precision machining shows in the fit and finish, and a gas block that sits true on your barrel is one less thing to troubleshoot downrange.

Frequently Asked Questions
What barrel gas tube size does the .750" gas block fit?
The .750" bore accommodates mid-length and rifle-length AR-15 gas tubes. If you're working with a pistol-length or carbine-length gas system, you'll want to verify your barrel's gas port diameter before ordering.
Will this gas block fit under my free-float handguard?
Yes. The low-profile design is specifically engineered to fit underneath free-float tube handguards, giving you a clean, unobstructed look and preserving maximum gripping surface on your rail system.
What hardware comes with the gas block?
All setscrews and mounting hardware are included. You clamp it to the barrel using the side-mounted setscrews—no additional fasteners needed.
How is this gas block different from typical manufacturers' gas blocks?
Sadlak machines every bore with precision honing and performs 100% dimensional inspection on critical measurements. This attention to manufacturing detail means tighter tolerances and more consistent fit than cast-and-finish alternatives, which matters when you're building or upgrading a reliable rifle.
