Brass breech Rampage?

just wondering if it's worthwhile/ possible to brass breech a Rampage, or if anyone has attempted a BB conversion on a Rampage/Retaliator?

Also, since I'm always time-poor, is there an online store that supplies brass?

Worthwhile? Probably.
Possible? Anything is possible with enough time/money; this is probably relatively simple though.
Supplier? Can't help you sorry.

I believe SG Nerf tried a brass breech on a Retal, and commented that performance was increased by 10-15ft using an 8kg spring, so the PTG ranges were about 80-95ft.
"Worthwhile" will depend on your ability to create said brass breech, but considering that you could break 100ft with one, I'd consider it worthwhile.

I am in the process of making a BB for the rampage. When I remember to go and get the 9/16 and 19/32 I will let you all know how it works/fails.

Gooni.

awesome, thanks for the input. gooni- please do let us know how it goes!
