Frequently Asked Questions

Is the Vltor FRE-15M compatible with my AR-15?

Yes—the FRE-15M is designed for standard AR-pattern upper receivers. It uses conventional barrel nut attachment and works with any mil-spec setup.

What accessories can I mount on M-Lok slots?

M-Lok is an industry-standard mounting interface. You can attach lights, laser modules, bipods, grips, and rail sections from most quality manufacturers that support M-Lok—giving you broad flexibility in your build.

Is the 15-inch length right for my rifle?

The 15-inch dimension is a mid-length option. It provides good coverage and support without extending too far forward. Fit depends on your barrel length and shooting style—shorter for pistol-caliber or compact builds, longer if you want maximum accessory real estate.
