New Knex Gun

Made this earlier. I made a cool handle and built a whole gun off of it. This is the result. I need to improve on the stock, and I guess that's about it. 

Features:
Comfy, Realistic Handle
Pin Guide
Low friction Barrel
Top-Loading, or Bottom Load (It has both!) Magazine
Extremely Solid
Very Powerful (Pin barely hits bullet, and gets maximum pin draw)

Tell me what you think, if I should post, etc.
