Got a M4-1000 and would love to get a few latch replacement (18T) springs. Anybody have a source? So far I searched the entire internet and can't find any.

Still looking!

Bump and would like to know as well, or off to try to make some...

Ditto and maybe a another mount lol

I had an old, old M4-1000 sent in 2 weeks ago after being on a waiting list for over a year with the new AAC. They have some 18T springs to do repairs. I don't know if they will sell any by themselves, but I was able to get new springs in my M4-1000.

I asked for new latch springs. You have to send it to the factory to have it replaced for $100 I believe. At least hats what they said for my m4-2000.
This will be my third latch spring replacement. Funny thing is, I babied the second latch spring replacement which lasted for maybe 2 1/2 years. It’s a bit ridiculous.

My m42k is a really great can besides this. Unfortunately sending it in every few years to get it replaced is not something I care to do for a lot of reasons.
So unfortunately I’ll be looking @ surefire for my next 5.56 can. I really wish hey would get their latch spring teeth to be more durable. Doubtful this will happen.
