Nerf Rampage Barrel Holder Exchangeable

Made this Barrelend/Holder for scientific purpose!

I will test different kinds of barrels for the rampage!
Just in case someone needs this...

Needs 2 spare screws (the ones from the case) or just tap M3 into it if you like.

Edit: Seems a straight barrel is the best. Ive uploaded an extension for the barrel ;)
