Nicely done! Are you going to build a cover to hide the parts?

Not very mini, but good job. Get a cover for the internals and paint it black, it will look great.

i have been meaning to find some plastic sheeting for the sides and then i was going to pant the white part the same as whatever plastic i get, and thanks for the comments.

:D

All hail the wooden stock!

I would remove the electronics from the stock before painting, then use a piece of clear acrylic or polycarbonate as a cover.

It looks very ergonimic, now it just needs some flat black paint.

I'm also intrested in your igintion, but anyway very nice looking cannon, you just need to paint over the stock and you're pretty much have a nice looking finished gun.
Is that a fake silencer or does it actually work?

its actually a Steyr AUG, Bull-pup is not actually a gun its a term used to describe aspects of certain features the main one being that the mag is held behind the trigger grip not in-front of it like most guns making a shorter total gun length and saving weight while also looking cooler :D

most people think its called a bull pop due to count strike calling it that so they wouldn't have to pay royalties :(
