❗️FREE SHIPPING❗️ Title says it all! This will extend your outer battle for the use of any 14mm CCW accessory. I strongly recommend only using these for something like a flash hider, as the material is only so strong. It is 3D printed with PETG filament. If your inner barrel needs to go through this, it may require some modification. Most inner barrels will fit through just fine, but some are too thick. • Available in black
