Yep! The 2 leather "legs" is what's broke.
Gotcha- I might be able to replace the broken leather piece... kind of looks like an add on after it was made. Not sure if I can sew it because it looks like it's got dividers inside. I don't mind trying.
I can take a look at it when I buy that PSA lower from you. Oh yeah- I'll take the PSA lower minus the stock/tube.
