Each Extension includes:
(1) Barrel Extension (in the wrap). I have not opened or cut the wrapping, so have no clue as to manufacturer.
(1) Barrel Lock Spring – NOS in the wrap. These are USGI for 30.06
(1) Breech Block – SG marked, one in the wrap, others are in excellent conditions as pictured.
(1) Breech Block/Accelerator Pin – NOS, in the white. These appear to have never been installed.
