Product Info for WMD Guns 5.56mm 6 Positions Carbine Buffer Tube

The new 6 Position Nib-X Buffer tube is a long awaited item for those who want the look of a traditional nibbed buffer tube but want the performance of a Nib-X buffer tube. The 6 Position Nib-X is a big hit with the younger crowd who want there guns to look like a 'normal' gun and not a "castle" build. This buffer tube can be used on a standard AR buffer tube pin, or a standard AR extended buffer tube pin with a longer overall length. We decided that a more aesthetically pleasing option than a plain ole' steel tube. So after a day at the range with our 6 Position Nib-X Buffer Tube, you may want to consider a more refined option. This tube has been extensively machined and anodized for wear resistance and durability. It is easy to install and even easier to remove.image
