I am selling a Brass Eagle Nightmare Long Barrel.
I shot 10-12 balls on Apr 15 and was getting 330ish FPS using some old Valken Bing ( around .689) . I did not hear any leaks.
I dumped oil in the valve and on the hammer area not knowing how long since it was last used ( Its a co-worker's gun).
It is beautifully loud and intimidating.
It does have some scratches and dings as would be expected for a marker of this age.
