I suggested a parts number/with photo thread a while back.
need a new upper
People said they liked the idea; but in reality, only those who have received parts in the past are able to supply numbers, etc.
Lack of factory supplied exploded view diagrams and parts lists causes S&W to drop further down on the list of acceptable manufacturers next time I buy a firearm.
I really don't like having to wait two-three weeks for a small, easy to replace part. In the case of the 15-22, S&W has a captive market. When it comes to revolvers, Semi-Auto and ARs, I'll remember the poor Customer service that S&W has...
(Yes, I believe that failure to supply and exploded view diagram and parts list is poor customer service.)
Not all replacement parts need to be installed by a gunsmith.
