Size Guide

This is a guide for matching up component sizes for tubes, caps, adapters, dividers, and spacers. It will not tell you what size to choose for your application. This is something that we cannot assist with and needs to be determined by you. Online forums are helpful in this regard.
We do provide all of the necessary dimensional information for each component listed on the product pages.
ASR Tubes are threaded on one end to accept the ASR Bravo, Keymo for omega, Griffin plan A, Q plan B, & YHM 1.375" x 24tpi adapters. The other end is threaded for SPC caps.
