NEF/Marlin B@#%%ds
I know this thread is supposed to be about fastest turnabout, but thought that I might add my experience with a major company.
Made the mistake several years ago of buying a cheap revolver, the NEF 9-shot .22, don't remember the model. (Swing out cylinder, solid frame)
Knew it wasn't great quality, but couldn't justify money for much else at the time, and it seemed robust.
Broke an internal part after about a brick or so.
Seems that when they reconfigured them to accept a transfer bar, they just slapped it in, and weakened a part that is under considerable stress when firing double action. The arm that transfers pressure from the trigger to the hammer, (can't think of the name for it now), had a hole drilled in it for a pin that held the transfer bar.
So it was a basic failure of materials.
No problem, they're supposed to have a lifetime warranty.
Sent it to NEF/Marlin.
They sent it back, minus the box and paperwork, and told me to get lost.
After a few calls, they send me a (wrong) replacement part.
Not amused!
Worst part is that I like NEF and Marlin rifles, have some and and will own more.
But their customer "service" is dreadful.
Bought correct replacement part, fixed it and had it running right, but didn't trust it anymore. Especially that it would hold up to DA shooting.
So I traded it at a loss, added some cash and came away with a Model 10 that is an amazingly sweet shooter.
Action so smooth I couldn't imagine having any work done on it. Holster wear, but tight and accurate.
