How to: Front Sight Install

This video demonstrates a DIY method for installing a custom-fit front sight on a CO2 gun using a salvaged rifle sight and JB Weld. The process involves precisely recutting the sight's contour to match the barrel diameter using a milling machine and endmill, followed by secure attachment with JB Weld. The instructor highlights the importance of accurate measurement and machining for a proper fit, even on a less expensive firearm.

Quick Summary

To custom-fit a front sight, recut its contour to match the barrel diameter using a round-nose endmill on a milling machine. Precisely locate the barrel's center with a DRO and edge finder. Secure the modified sight to the barrel using JB Weld for a durable installation.

Frequently Asked Questions

How can I fix a melted plastic front sight on a CO2 gun?

If a plastic front sight melts, you can source a metal sight from another firearm, like a Remington 600 rifle. You'll then need to recut its contour to fit your barrel using a milling machine and a round-nose endmill, followed by securing it with JB Weld.

What tools are needed to custom-fit a front sight?

To custom-fit a front sight, you'll need a milling machine, a round-nose endmill matching your barrel's diameter, a digital readout (DRO), an edge finder for precise measurements, and a strong adhesive like JB Weld for installation.

Can JB Weld be used to install firearm sights?

Yes, JB Weld is presented as a reliable adhesive for installing firearm sights. It's noted to be strong enough to hold even on firearms with significant recoil, making it a viable option for DIY sight installations.

How do you ensure a front sight fits precisely on a barrel?

Precise fitting involves using a milling machine with a round-nose endmill that matches the barrel's diameter. This allows you to recut the bottom contour of the replacement sight to perfectly match the curve of the barrel for a secure and accurate installation.
