60+ feet range with rod bullet and no fins (with only 2 #64 rubber bands...!) Or 100+ feet (with 5 #64's)
around 50+ or so feet per second (my Ak-47 with same mechanism and power got that...might post if get requests)
power = 1 inch penetration of very thick cardboard box with sharpened red rod on yellow connector at 1 foot of range =) Or with 5 rubber bands at a few feet with a yellow rod on yellow connector it pierced all the way and the connector went halfway through the box. =)
magazine: don't work as a magazine because its a sling mechanism (they own) but it can hold bullets:number varies on type of bullet)
stock: from the winchester
made to compete with: I don't know, maybe all those carbons with clip trigger system?
Step 1: Parts lists =)
