Availability: In stock

* Required Fields


Our Keyed Carbine Buffer Tube is manufactured exclusively for Thordsen Customs and is ideal for use with either our FRS-15 Rifle Stock or AR/AK Cheek Rest kits.

It is a hybrid design, combining the strength of Mil-Spec rolled threading with the heavier walls and length of a commercial buffer tube. They are made without the slot and detent holes. This gives it a clean look and eliminates the ability to lock an adjustable stock onto it.
