Abstract
A method of forming a solid-core carbon fiber barrel or carbon fiber gas port barrel for use with a firearm and related kits.
Claims21
A method of forming a barrel for a firearm comprising the steps of:
- winding a first dry prepreg carbon fiber to form a carbon tube with a first diameter, wherein the winding comprises a vertical angle from 0 to 25 degrees;
- winding a second dry prepreg carbon fiber to form the carbon tube with a second diameter, wherein the winding comprises a vertical angle from 30 to 60 degrees;
- bonding the carbon tube to a steel barrel core, wherein the carbon tube is bonded to the core with an epoxy or resin;
- wrapping the carbon tube bonded to the steel core with a compression tape;
- curing the carbon tube bonded to the steel core;
- grinding the carbon tube to a third diameter;
- and
- sealing the carbon tube bonded to the steel core.
