Thread Pitch Adapter Guide

There are many thread pitches out there, but we’re here to help. Each firearm has its own thread pitch, and most thread pitches are universal to the style of weapon and caliber.
We have put put together a comprehensive guide below which lists the most common thread pitches for firearms. USASOLVENTTRAPS strives to make it as easy as possible for our customers to understand more about their thread pitches and what is the best fit for your firearm!
