Lurker Lube "juiced" is specificly designed for spool markers.
Raz's oring kit is WELL worth the $30.
eigenring helps with efficiency tremendously.
Only other thing I would suggest is a full set of Dye UL barrel backs, or a barrel that accepts bore size inserts. And possibly a B-Wing bolt if you wanted, Though the Lurker Lube and Raz's O-rings will polish your bolt for you over time, which is all the Bwing is....poslished..
Other than that, the gun is out of the box ready to do damage.
