Sylvan Arms GCB100 Glock Conversion Block Black

Description

Product Overview

The Sylvan Arms GCB100 Glock Conversion Block is an aftermarket aluminum insert that lets you run 9mm Glock 17/19 magazines in a standard mil-spec AR-15 lower. Install the conversion block into the AR magazine well and, with most compatible 9mm AR uppers, you can build a pistol caliber carbine using Glock-pattern pistol magazines.

Key Features

• Converts a standard AR-15 lower to accept Glock 17/19 style 9mm magazines
• Aircraft grade 6061 aluminum construction for strength and durability
• Black finish for a clean, compact install
• Trigger-style magazine release design for quick one-hand magazine removal

If you want an AR-15 platform that uses Glock 17/19 magazines, the GCB100 conversion block is a purpose-built option designed for that compatibility.
