My brief review of the seller suggests almost exclusive sales activity and very little forum content or engagement.
In my eye, he is a mass seller and straying into amateur or pro trade sales.
If this is new, and within warranty, I would have agreed return if rifle for warranty work. The warranty may only be original purchaser. That would have been a reasonable interparty solution.
The seller is ising caveat emptor in a spirit I find a bit cold and cynical and to be frank, just underlines a trade seller at best.
I think the mod team perhaps need to have a bit of a purge on 99% sales threads or perhaps members can raise a flag on members whos activity is based on flogging stuff.
In a battle of wits I refuse to engage with an unarmed person.
To one shot one kill, you need to seek the S. Kill only comes from Skill
