Mad Bull Airsoft JP Rifles RIS

[Micleo]

I really want a new RIS for my G&G R4, and I found these items through my interweb burrowing...

I absolutely love the JP Rifles RIS! But, before I decide on buying one, I have some questions!

I have a standard length M4 barrel on my R4. So here's the Q's!
- Do I need a new inner barrel in order to use the 16" outer barrel I'd be getting? If so, what's involved there?
- Where can I get this RIS? I would be happy to buy a used one, I don't even care if it's banged up. It'll look that way regardless, anyways.

Thank you all for your help in advance, I appreciate it!

P.S. Just curious, where can I possibly get myself a 7" MadBull Dragon Fire CNC Handguard? Thanks

you dont NEED a new inner barrel but since you are extending the outer it would be a great idea to extend the inner too...

i bought mine at airsoftpart.ca

and i think they also have the madbull dragon fire... not sure...

You don't need a new inner barrel but it's a good idea because it's kind of a waste of a long outer barrel if you don't.

You can find the 7 inch Dragon Fire rail at many, MANY online airsoft stores.

I have the 12" JP Rifles kit for my M4. Came with 4 outer barrel extensions. I haven't tried the longest the 2nd shortest works best with the 509mm inner.

It doesn't come with enough rails though.

Thanks all of you! It looks like I have all the information I need now. I'll get myself the conversion kit, and go from there...
