According to what eBay told us, the M4 shotgun is considered to be an "assault shotgun" and parts for such are not allowed on its site. It is okay to advertise the tube as for the model M1014 shotgun. Harlan

We had a message from 'Rob' but the phone number left was not complete. Thanks. Harlan

Here is a pic of the +2 steel tube we offer for the M4. Thanks. Harlan NoDak Spud LLC

We are now offering the steel +2 extension tube with a gray parkerized finish. Thanks. Harlan NoDak Spud LLC
