This video tests the accuracy and heat resistance of a Faxon 16-inch pencil barrel on a WWSD rifle. The test involved shooting groups before and after heating the barrel significantly with a suppressor. The results indicate that despite the light profile, the Faxon barrel maintained good accuracy with minimal point of impact shift after extensive firing.

Quick Summary

Light profile pencil barrels, like the Faxon 16-inch tested, heat up rapidly and can cause accuracy issues due to distortion. However, Faxon employs special stress-relieving procedures that help their barrels maintain good accuracy, with groups remaining around 2.5 MOA even after significant heating.

Frequently Asked Questions

Does heat affect the accuracy of a Faxon pencil barrel?

Yes, light profile pencil barrels heat up quickly and can experience distortion and point of impact shift. However, Faxon's special stress-relieving procedures help their barrels maintain good accuracy even when significantly heated.

What was the accuracy of the Faxon pencil barrel before heating?

Before significant heating, the Faxon 16-inch pencil barrel on the WWSD rifle achieved a 2.1 MOA five-round group, which is considered quite good for this barrel profile.

How did the Faxon pencil barrel perform after being heated?

After rapid firing multiple magazines with a suppressor, the barrel was smoking hot. Subsequent five-round groups remained around 2.5 MOA, indicating minimal degradation in accuracy.

Why are pencil barrels susceptible to heat-related accuracy issues?

Pencil barrels have a very light profile, causing them to heat up faster and reach higher temperatures. This rapid and intense heating can lead to thermal expansion and distortion, potentially shifting the point of impact.
