If you are a gun manufacturer, you might consider using our barrel liners for your barrel application. Many companies have used our liners making a lightweight barrel by injection molding, carbon wrapping and using an aluminum jacket around my barrel liner. One type of barrel replacement has been for the Ruger 10-22. These barrels have proven to be very accurate. The advantages to using my barrel liner vs. a standard barrel is as follows:
- Cost savings in production time
- Being able to make an accurate lightweight barrel.
- Achieve better accuracy. The synthetic or aluminum jacket seems to dampen the shooting vibration, allowing the barrel to be very accurate.
