Halo SMG with connectors 125% scale

Remix of the Halo 2 SMG by @brentglover1970 and fixed a few things.

• added joiners and connectors for the foregrip, magazine, stock slide, laser and laser connector.
• fixed the charging handle to have a larger surface to fit to the upper for strength
• removed the studs on the lowers grip as they kept falling off
• changed to size to be 125% of the original for life size prop

I hope you all like the changes as I am very novice at modelling so might not be perfect but allows for easier assembly.
