Nuff said, just seems that it might be kinda tight will it fit without modding and how would you ensure not to get it stuck inside?

Thats the bad part. I had a Python kit and it seemed no matter what I did the back kept getting stuck in the body. Thats why I switched to a freak back. Its long enough tonot have to worry about that. Also you can use a DW barrel.

Will the back actually fit down there though?

It was a tight fit. You may be able to loosen the screws of the body to get an easier fit putting it in then screw them back when its in.

Yes I've been able to get it to fit. However, changing the fin for bore size is a real pain in the arse.

you might be able to tightly wrap some electrical tape or duct tape around where the barrel meets the fin? but i guess that would make them hard to swap out.

Well, I went ahead and ordered a Widowmaker for it. I figure if it's a good barrel however, it's not like I'll be changing it anyhow.

Well, I got my Widowmaker in and yeah I had to loosen the screws to get it in but after that it was fine, looks great on there too. Problem is that it's so short I can't fit the APEX 2 on it even with an adapter. I'm still gonna use it though cuz it's such a sweet barrel. I may bet a MoFo later on and just keep my fin in there. That should give me enough clearance for the APEX 2.
