Buying the collapsible stock/tube/buffer/spring set and a 16-inch upper would be much cheaper than buying a new rifle.
DSArms offers their "ZM4" 16-inch A3 upper for $275 without B/C/CH www.dsarms.com/
Brownell's offers a complete collapsible stock kit for $80 part# 080-000-545EE
This way you would still have your original parts and could swap back-and-forth if needed.
