I'm sure this topic has been beat to death a few times before, but i'm new to the mini-14 & the site. I've found a few see thru mounts but I would like some of your inputs on wich ones are the best for a 581 series. 2 that seemed to stand out are the B-square see thru rail model#14507, & The country Shed model MNT-214. I also liked the design of the Weaver see thru rings model#49723 but i heard they block the rear sight on the 581 series. Thanks for any feedback.
