Advanced Technology LOP Quick Stop Features The Advanced Technology LOP Quick Stop is machined from 6061 T6 aluminum and finished in a black anodized coating giving it the durability to stand up to repeated stock adjustments without wearing out. Its core function is repeatable positioning so every time a shooter extends or collapses their stock it returns to the same length of pull without having to count detents or guess. An integrated anti-rattle spring keeps the stock snug against the buffer tube eliminating the wobble and noise that loose stocks are known for. This combination of precision machining and a tensioned spring delivers a tighter more consistent fit than a stock stop alone. Compatibility is straightforward as the LOP Quick Stop works with Mil-Spec buffer tubes and stocks covering the vast majority of AR-platform rifles and pistols on the market. Shooters who share a rifle between multiple users or who break their setup down for storage and transport benefit most from the repeatable positioning this part provides. The black anodized finish matches standard AR hardware so the Quick Stop blends in without drawing attention on a build. The Advanced Technology LOP Quick Stop is available for sale at GrabAGun for shooters who want a dependable repeatable stock setup every time.
