If you disassembled it you may want to contact Gamo directly and see if they can help you with a diagram. Call 954-581-5822 Gamo Customer Service. Unlike Crosman who post schematics for all their guns and rifles, Gamo and Daisy does not. Your next best shot is to check the web for an "Air gun repair" shop and send it to them for assembly and repair.
What is a gamo del tamatic? I can not find any information on it.

What condition is it in? without some sort of description about the condition, it is not possible to answer you. Is it in Poor, Fair, Good, Very Good or Excellent condition.
Gamo extreme hunter
The Gamo Silent Cat fires .177 caliber Pellets not BB's.
You can purchase a Gamo air rifle at your local Walmart retail store. You can also purchase one online from the Amazon website and have it shipped directly to your house.
I don't believe that Gamo it still making the Hunter Sport anymore. But It may still be in stores. The Crosman Phantom 1000 has great reviews but I would lean towards the Gamo as my choice. But it's all up to you.
I suggest you contact Gamo Customer Service with this question. See the link below
Yes it is. It is a single shot .177 pellet rifle. It is not a BB rifle.
I would contact Gamo directly for the best answer. See the link below. You do mean "GAMO" not Gamco
Gamo never made a Sniper model rifle. It depends on the model, each one is different. You need to locate the model number and ask your question again.
Get a GR3T trigger for it. It is considered the very best trigger available for Gamo. See the link below
