Italian_guy299,
Unfortunately your link ask for a postal code before it will proceed to the website and I do not have a Canadian postal code.

Italian_guy299,
Thanks for the Walmart link. Much appreciated.
Here is an interesting website concerning the Crossman M70 gun and several links showing how to cut the gun down to a smaller size: tgi.net/~andrew/?p=22

Interesting. Originally I planned to mod the gun, however I decided not to for safety reasons. There are rules I have to follow when entering my local science fairs and all these rules must comply with CWSF (canada wide science fair). To make it there I have to follow these rules. 1 being not to modify guns/ammo(this is considered a gun by CWSF since you must be 18 to purchase it).
You would probably get better accuracy and control if the gun mount was ridgidly mounted to the bot and the gun tilted on the mount itself. Look at the below setup to see how to tilt a mounted object using a simple linkage. This would allow for much finer aiming and the gun would be steadier on the mount. Bottom is the UZI which might be more compact.

Thanks for the comments guys. Its too late to change my project for the science fairs, but I plan to continue with this project until I am satisfied with its performance. Its a project I am very fascinated in and will be complete when I say so 
UPDATE: It is kind of a late announcement, however, last week the MARC took home a gold medal in my school fair. Iāve just completed my registry for my regional fair and if all goes well I may end up with a gold there as well a long with the grand prize to Ottawa for the Canada-Wide Science Fair (won that last year).
BTW: i just recently downloaded Google Sketchup and I must say it is very good! Its not exactly a 3-D imaging program like autocad, but it is very good for modeling chassisā etc. I highly recommend it to newbie CAD drawers.
Heres my first CAD ever:

Its pretty good however it isnāt to scale as I just learned how to measure lines etc using the tape measure tool. Over all a very good and user-friendly program.
Got any pics of the medal?
Google Sketchup is quite simple. Thats the first program I used. Very quick, easy to use interface.
Looks cool and congratulations.
You can do some pretty intense things with sketchup. Depends on how good you get at it. I hate that it doesnāt have drill points though. And it has serious issues with exporting DWG and DXF files.
yes, I wish it had drill points too.
And heres the gold:

Nice!
Congratulations! Keep up the good work!
Thanks Zenta, Cudos for winning the Trossen Robotics competition as well! 
Here is the final project for my regional fair this week:

comments?
I think you should be very proud of yourself. You did an outstanding job.
I think the board and robot look terrific.
Thanks, Evo!
your robots are terrific and an inspiration!
Thanks bud. And you spelled reconnaissance right. lol not alot of people do. Not even reconnaissance soldiers. Really.
I remember words better when I keep forgetting how to spell them (lol if that made sense). Im just glad I know reconnaissance has two Nās and Sās.
Its dissapointing to say that I didnt make it to Canada Wide Science Fair. Actually no decent project did. The judging at this fair was unbelievably difficult - more than ever! Neither of the judges were interested in any of the robot projects and most of them didnt do very well.
Here are the results: 3rd last Silver Merit in the Fair, 6 Engineering awards (mostly mechanical of course) totalling 730$ CAD. I was also the highest merit with a robotics project (in other words no one else with a robotics project got past bronze, and they were VERY GOOD).
Part of the reasons as to why the judging was especially hard on robotics projects was that the judges thought we didnāt DIY. Geuss they forgot to see my 63 page report 
All in all, the Canada Wide trip went to 16 others, while the 3 robotics projects remaine in town. Future science fair plans or projects are sketchy at the moment for me, so everything here on will be robotics experimenting in my free time. Its been an interesting year completing this project and in some ways im glad its over. I can now move onto something else that interests me.

As posted in the thread last August: āIf this is going in a science fair, where is the āscienceā in the project? A judge might think it is just an RC model project.ā
Hello sir a hearty congratulations 
to your bot just love it ,it will be a great pleasure for me if you teach me that how the gun shooting system with laser and camera aiming works in detail and how you made your bot water resistant
