Hastings Metro Barrel INV+ NIB

The Metro system is a barrel extension that is specially ported to reduce muzzle noise by half. The 32" extension installs easily in seconds by threading on in place of a choke tube. No modification to the gun is necessary, and the Metro will even accept your gun's original choke tubes. Blue matte, 12 gauge. •32" overall length •Extension is screwed into choke tube threads •Metro tube is threaded to accept original choke tubes •Tube is drilled to help reduce recoil and noise •Heavy loading will not harm Extension •Includes wrench This tube is for Invector Plus choke tube systems. $99.00 plus $16.00 shipping to lower 48 states. I would be very willing to trade two of these barrels for one with Rem-Choke threads in NIB condition.
