I didn't take mine down completely, rather I field stripped it, put it in an heated ultrasonic bath, then clean boiling water, compressed air, water displacing oil and then let it sit in ATF. More compressed air, grease and oil on appropriate spots, reassembled and shot. What a fun gun to shoot! Mine was pretty accurate even though the grooves were frosty.

Taking it out again next week and will shoot from rest to see how good we really are.

Thanks to Bob for his help.
