Specifications

Frequently Asked Questions

Will this front sight fit my rifle's barrel?

This sight is designed for rifles with a dovetail cut directly into the barrel. The 17/32" wide base with rounded sides fits standard barrel dovetails. If you're unsure whether your rifle has a barrel dovetail (as opposed to a ramp-mounted sight), measure your dovetail or consult your rifle's manual. This sight does not work with ramp-based front sight systems.

What does the "W" designation mean?

The "W" indicates the width of the base—17/32" in this case. Marble Arms offers front sights in different base widths to match various rifle dovetail specifications. If your rifle's dovetail is a different width, you'll need a different sight base size.

Can I use this sight with a rear peep sight?

Yes. This front sight is designed to work with Marble Arms rear sights or other compatible open-sight systems. For best results, pair it with a matching Marble Arms rear sight and refer to their sight selection chart to ensure proper sight heights for your rifle.

What's the finish like—will it rust?

The sight is steel with a brass gold finish. Like all steel sights, it will benefit from routine cleaning and light oiling to prevent rust, especially in wet or humid conditions. The brass gold tone will develop a patina over time with field use, adding character to your rifle.
