I just recently purchased a G&G M14 and the wolverine kit from amped-airsoft to convert it to a HPA system. My question is is that I want to shorten the barrel a bit since it is a standard size M14, mainly to eventually accommodate a suppressor and not make it so long with the added length. Would my best option be to:
-Find someone/somewhere to cut my outer barrel and re thread it?(is this expensive?)
-Purchase a shorter barrel?(If so, does this one work?)
-Some other option?

Thanks for your time.
