"Works as intended, did have to shave part of one tooth for the best 1st contact with gear. This was expected.

"The piston seemed like it was came out of a boneyard gun. Mine came with stripped teeth up to the ninth tooth. It will still work but not for long.


-Nice ported piston head w/ bearings
-Hard material


-Old nasty grease!
