Home Forums Hunting & Shooting Hunting Rifles Details on this Ruger?

Ran across an interesting Ruger today, an older 77 tang safety in .30-06. Prefix was 772-, so should have been a '90 model. What was interesting about the rifle, it was a UL model with pencil/lightweight barrel and express style rifle sights. I am not sure what the barrel length was, but assume either 18.5 or 20". It was a really lightweight setup, with a black recoil pad.

Any ideas what the model number would be on this one, and how rare are they? Sorry, no pics...

It might be an RLS

RLS or an RSI in a different stock

Yes, an RLS....Rifle, Lightweight, with Sights
