This is my $30 pump. That's right, I paid $30 for the pump and 12 gram CO2 adaptor. Paid $2 to make the feedtube.
The Marker is a 1991 Razorback. It really dosn't have any upgrades (none really exist). It does have:
A modified spring which gives it 280 fps while using a 9 gram CO2
A homemade stock class feed tube, PVC pipe, cap, and elbow. The cap is attached by a string. It's been used a lot this fall as some of the black paint on the feedtube has worn off due to being used.
Now for the pics:
