Don't know how I stumbled across this... But here's another golden reference!
Full pictures and discussion here:
A (perhaps) Silly Question
L4A4 ejector block on left.
L4A1 ejector block on right with hold open device 'button' behind the mag catch
FN (FAL) locking lug top (L4A1 type) (top)
Commonwealth locking lug bottom (L4A4 type) (Bottom)
Confirmed:
L4A4 used a 30 round mag, staggered rounds.
Looks like it also used a shorter 20 round mag as well, but I've already modeled the 30 round mag... I'm sure the guys on Goose Green will like how that worked out
It looks like the whole mag catch assembly swings upward on rotation of the pivot point (?) once the lever is pushed forward toward the mag (?)... Wait a second...
Here's the problem I have with this...
It looks like from the ref of the magazines that the locking lug is the part that is held onto and that's what keeps the mag in the receiver.
And the lever swings along a pivot that brings the most z-axis southern lip of the lever toward the leaf ironsight, which then releases the magazine locking lug and allows the lug to pass:
It also looks like there is a lip on the mag catch release, or a rim that slides into a slot in the receiver, along a very specific slot, then a bolt that keeps the mag catch apparatus in the receiver, not a pivot point. In other words, it looks like there is a very specific slot and position that the mag catch apparatus maintains at all times, and the only thing that moves is actually the release lever, which has a lip on it's most southern extremity that holds (or releases) the magazine's locking lug.
There is extra space that leads me to believe not that the whole apparatus swings, but that the apparatus has room to be lowered into the receiver and moved into position along the slot, then the bolt goes in to keep it in place. Maybe even a rivot (?).
Also, the diagram you provided, Strima, would only mechanically work if the spring was on the left like so:

Not to be a deushbag but more just because it didn't look right. That's what got me on the search.
Can I get some agreeance on these points, or naysayers (is fine as well)? Let's talk about this now and come up with a concensus before I get too deep into modeling this.

Cool... Then just to confirm, this won't be seen in 1p obviously, but for 3p this should be a normal map?
