Oringinally it was the ‘Original’ DPMS 24″ SS Bull barrel .308. About a year after I bought it I had DPMS in St. Cloud redo/customize it:
1. Replaced the original no-rail gas-block with the 4-rail gas block.
2. Cut/re-crown the barrel to 22″
3. Flute it
4. Change upper receiver from the slab-side to the AP4-style w/ forward-assist and dust-cover.
DOES NOT INCLUDE OPTIC OR MOUNT.
