Replacement Liner

[neond7]

How easy is it to obtain a replacement liner for a 4gr 75mm RMS motor?
I have had an L900DM in the box for a few years, started to assemble it and cut my finger on a sharp edge. Looked at the liner and it had a huge chunk missing!
The liner was nicely wrapped in layers of bubble wrap from Wildman so i don’t think it was damaged in shipping.
Are the liners sold, or can aerotech just replace it?

I had a similar missing chunk on a 75mm M liner, but mine was the result of dropping it on the garage floor. Know what sound sucks? Hearing bits of liner bounce around on the floor right after the liner hit.

I was able to get a new liner from our onsite vendor (AMW) with no fuss.
