HK 50236720 Slimline Black Polymer Retractable Fits AR-15/M16
$80.00
The Heckler & Koch 50236720 Slimline Black Polymer Retractable stock is a purpose-built AR-15/M16 buttstock designed for shooters who value compact handling without sacrificing stability. Built from tough polymer, this retractable stock collapses for easier storage, transport, and shooting in tight spaces—ideal for home defense, patrol, or hunting scenarios where a shorter length of pull matters. H&K engineered this stock for reliable performance on the platform it was designed for, making it a solid choice for rifle builders and operators upgrading their AR platform.
Retractable stocks have become standard on modern tactical and sport rifles for good reason: they let you adjust the length of pull for different shooters, gear configurations, or shooting positions without swapping hardware. The slimline profile keeps your rifle's profile compact and reduces snag risk when moving through brush or tight quarters. Black polymer construction is durable, weather-resistant, and low-maintenance—no rust, no rattle, just dependable function.
Whether you're building a rifle from scratch, modernizing an older platform, or setting up a versatile home-defense AR, a quality buttstock is one of the most practical upgrades you can make. This H&K retractable option gives you the control to fine-tune your setup without breaking the bank or adding unnecessary weight.
