Big Bang Inners

I'm new to the Modelguns so I may ask some dumb questions. I recently purchase a Marushin MP40. I just got some 7mm caps off eBay and fired the gun for the first time yesterday. It fired fine with the cartridges loading and ejecting well. I was disappointed that there was very little noise. An eBay seller lists an item called "Big Bang Inners". Can anyone tell me what they are for? Do they create a "bang"?

Why not contact the seller directly?

I don't think your expectation for a huge bang should be set too high in your particular model. A single cap cartridge that is used in a Marushin MP40 will not be too loud.

The ebay seller of the big bang inners is Francky - and all of us forum members are familiar with him. He can probably give you more info if you reach out to him.

Also - welcome to the forum and the hobby!

Please check out the video section to see more of what these models are capable of in order to set your expectations to a realistic level. Enjoy!!!!

I did contact Francky about them and he didn't reply.

Hi, can you give me the link to get 7mm caps on eBay? I done a search but I don't see them.

Cheers.
