That actually looks like a really good model to me. I like the blocko style of it.
Call it the BL-74U.
I added the trigger after I posted it in the 3D model megathread.
I still need to fix a few things on it, like the sights, magazine, roostering bolt, and ejector port.
And I got lazy on the mag. I'll fix it.
I think this is my 3rd one so far.
