Precision-engineered adjustable gas block for .750-diameter AR barrels. Durable construction, low-profile design, and easy installation optimize rifle performance and reliability.
The Luth-AR .750 Adjustable Gas Block represents a straightforward approach to tuning your rifle's gas system. Designed specifically for barrels with a .750-inch diameter, this component allows you to fine-tune the amount of gas cycling back into your bolt carrier group.
An adjustable gas block gives you control over your rifle's reliability and comfort. Too much gas creates excessive recoil and accelerated wear; too little risks short-stroking. This block lets you find the sweet spot for your ammunition, barrel length, and shooting conditions.
Whether you're running suppressed loads, handloads, or factory ammunition, the ability to adjust your gas system is a practical advantage. This is the kind of upgrade that separates a good rifle from one that runs exactly how you want it to run.
