Haven't even shoot the gun yet but I've used my bro's Sonix,
couple ?s.
with the Xtra having the Derlin bolt I won't be doing any polishing mods will I?
and I took the bolt out, but didn't notice a ventury is this correct?
is there any write ups on modding anything on the 07 Xtra?
yeh usually a delrin bolt wont have a venturi just a different design on the front of the bolt. and i really havnt seen anything done to an 07 xtra yet but there is plenty u can do to a spyder...
