Post Apoc Rifle Pt 2

Well, after a few tests with my new birthday present we realized there where a few problems with my older design. Being a child leads to that sometimes.
The first thing Reg 'nd I did was change the grip, we found and carved a new rifle grip but we had to screw it into the reciver and and stock.
The second thing we did was create a new holding mechanism for the rounds, there was a constant issue of the slugs not fitting properly into the barrel when shot because there was no cylinder of any kind. So we abandoned the old idea of just having them attached to a chain since pushing them forward would be to complicated.
And just for fun we changed the trigger gaurd so it would look a little classy.
Luckily I haven't managed to to damage this one yet, but I'm sure it won't be too long now.
I never did find one of those tentacle monsters for Trish yet... Maybe I'll just name the gun after her instead for her birthday...

The idea for what to use for the cylinder I believe was from Robbe. If wrong just say so.
And again, NO I did not take any ideas from Borderlands. Revolver Rifles existed in real life too!
