I went with OTE guts. I had to do a little sanding for fit on the standard reed that came with it. Right now I can't tell the diff between the OTE and the orange guts I had in the poly mag. (I don't remember who's them are). I'll break in the "broken in guts" before judgement. I have to wonder what the CCC guts would have been like, being 7 bucks more. Ha.
The first poly mag I got was great, but it disappeared. The 2nd one I got for the boys ran about half as good.
It had the set and forget guts in it. I can't remember what the first one had. The tone board wasn't a clean molding so I don't believe it came from the Grounds Co. Thus the reason I had the orange guts. The call was an Ebay buy
