Is a new spring required with M4 factory extension?

A friend is buying a Factory Benelli M4 two shot extension and asked if he needs a new spring with this setup?

I said duh... I need to on Benelli USA Forums to ask.

I couldn't convince him to buy a one piece mag.

Thanks in advance for the answer.

I just shot my M4 for the 1st time last weekend with a factory Benelli + 2 extension tube (# 81043p) with stock spring & put about 100 rounds thru it with no concerns.I am puting a full length tube on it tonight & will be selling the Benelli + 2 tube. Looks like new($75.00 shipped) or best offer.Please contact me by e=mail or phone. Shipped from sarasota florida :)
