Frequently Asked Questions

How do I adjust the comb height on my shotgun?

To adjust comb height, you typically use Allen keys to loosen the comb's mounting screws and add or remove plastic spacers between the comb and the stock. More spacers increase height, fewer decrease it. Ensure consistency and check alignment.

What is 'cast' in firearm stocks?

Cast refers to the sideways angle of the stock relative to the barrel's bore. Cast-off angles the stock to the right, and cast-on angles it to the left. This adjustment helps align the shooter's eye perfectly with the sights.

Why is pattern testing important for adjustable combs?

Pattern testing is crucial because it verifies that your adjustable comb setup correctly aligns your point of aim with the point of impact. Even if it feels right, testing confirms accuracy and identifies any discrepancies.

Can I adjust my own firearm's comb?

Yes, you can adjust your own firearm's comb, especially with systems like Beretta's B-Fast. However, for optimal results, especially for competitive shooting, professional gun fitting by an expert who has set up thousands of guns is highly recommended.
