Frequently Asked Questions

Will this fit my AK rifle?

The VG146 is designed for AK-platform rifles that accept mil-spec stock tubes. Mil-spec is the standard across most contemporary AK variants, but verify that your rifle's receiver is drilled and tapped for a mil-spec tube before ordering. If you're uncertain, check your rifle's documentation or reach out to the manufacturer.

What stocks can I use with this tube?

Any stock manufactured to mil-spec AK dimensions will fit this tube. The mil-spec standard ensures compatibility across a broad range of aftermarket and OEM stocks, giving you flexibility to choose furniture that matches your needs—whether you prioritize length of pull, storage, or ergonomics.

Is this a direct swap on my existing AK?

If your rifle already has a mil-spec tube, the VG146 is a direct replacement. If your AK uses a different tube design, installation will require work beyond a simple swap. Verify your current setup before purchasing.
