I hope this helps you,
What do you mean by 3/4 magazine?
Fropm what I can see this has a tube mag, disappointingly the insert for the mag is missing.
It means the tube goes 3/4's of the way down the barrel. The inner mag tube assembly is available from Numrich Gun parts for $23.35. http://www.gunpartscorp.com/catalog/Detail.aspx?pid=229840&catid=4525
