Advanced Technology LOP Quick Stop Black Anodized 6061-T6 Aluminum - AR-15 Mil-Spec Buffer Tube

The Advanced Technology LOP Quick Stop is a precision-machined length-of-pull locking accessory designed for AR-15 rifles equipped with Mil-Spec buffer tubes and adjustable Mil-Spec stocks. It gives the shooter a positive, repeatable lock point so a collapsible stock will not drift or walk under recoil, making it ideal for users who run adjustable stocks but want a fixed LOP for a consistent cheek weld and improved accuracy.

The Quick Stop is machined from 6061-T6 aluminum and finished in a durable black anodized coating for corrosion resistance and a low-visibility look. It is compatible with standard Mil-Spec buffer tubes and the broad range of Mil-Spec carbine stocks on the market. A built-in anti-rattle spring eliminates play between the stock and receiver extension.

Specifications include a length of approximately 4.75 inches, a width of 3.05 inches, and a height of 0.40 inches, with an installed weight of roughly 0.06 lbs. The unit carries ATI's Limited Lifetime Warranty and is backed by the company's patent-pending design.
