Thread Reference Guide

Barrel Thread Reference Guide

In this firearm barrel thread reference guide, Infinite Product Solutions lists all the most common barrel thread sizes we get requests for. Please keep in mind that this barrel thread guide is meant for references purposes only.

Just because a barrel thread pattern is listed here, that does not mean we currently have an adapter of that thread size in stock. If we do not currently have the barrel thread adapter you need, we will be more than happy to make you a custom barrel thread adapter to any specifications you may require. Call us at 1-951-220-7948 for details!

In our world today, there are so many barrel thread patterns that exist for rifles, shotguns, and pistols. For faster and easier identification of what you may need, this barrel thread guide lists only the most commonly requested thread patterns.

If you cannot find the thread pattern you are looking for in the barrel thread reference guide below, or if you still have questions about barrel thread sizes, please send us an email or give us a call at 1-951-220-7948. Enjoy!
