Nice project,,love the Mannlicher rifles.
I'd include the small spring loaded 'door' on the bottom of the existing magazine system to capture the expended enbloc clip. Often seen on the GEW88 sporters, I've seen them on the Mannlicher sporters as well.
That keeps the magazine & feed system in tact. IMO that's much of the charm of the rifle to begin with.
I have a sporter carbine built on a Romanian M93 Mannlicher.
A betw the Wars build as it was a bring-back souvenier from WW2.
It has DST and they cut on the orig trigger guard and inserted a shotgun style trigger guard to lock into it to give the extra room for them.
It also gives a nice look to the now full stock carbine.
I can dig it out and post some pics of the carbine and the DST & how they worked over the trigger guard(s) if you'd like.
Just gives another way of doing things, maybe some ideas for you.
