New grendel, wont fire

[leopard6.5]

But Bill we're supposed to be a Horde and should be allowed to act like it shouldn't we! Just Kidding in case anyone wondered.

Deezil: You said the shop claimed they built it but then they said they bought it straight from AA. Does that mean they just bought the loose parts and then assembled it themselves?
At first it sounded like they bought a completed upper( or rifle) from AA and just were the middle people.
Do you know which particular AA ammo they used when they fired the rifle?

Thanks for the further info and good luck with getting this straightened out.

PS- I have to second the recommendation to send it to AA if you can't get it fixed otherwise especially if time really starts getting critical.
