Brownells Delrin Ring Reducer, 30mm to 26mm

This Brownells Delrin ring reducer lets a shooter mount a 26mm-tube scope or optic in 30mm rings, sleeving the smaller tube diameter up to fit securely without gaps or slippage. Delrin construction protects the scope tube’s finish from ring marks.

A practical, low-cost way to reuse existing 30mm rings with smaller-diameter optics.
