4.25" Rifled FGC9 or Mod9 barrels. These have been turned out of button rifled blanks and are drop in replacements for the ecm/shaft collar barrels.
BLEM: these will require minor modification to work in your build. Some will drop in as is but have damaged threads, while others have slightly long or short trunnions and will need to be shimmed.
We will be out of the office until 20 May while we travel to celebrate a military commissioning. We will be back soon and your order will process ASAP!
