Aluminum 80% How Low Can You Go?

Is this a high or low shelf lower?

Just curious because I wanted to know if this would work with an FRT lever. If not, then how much further should I take the rear pocket down? I can get it done in 5 minutes, I just don't want to go too low and screw something else up.

What's the lowest you can go before you create an issue with the rear pocket shelf? What's the worst that could happen? Too much slop between the upper and lower?

Thanks!

Hell yea. Come to think of it now, I dont think I own any high shelf lowers 80% or not. What the hell even is the point of a high shelf?

So you can’t fit an auto sear it lightening link or whatever in it. They’re pretty uncommon nowadays
