Shocktech bolt not fitting?

[spray and pray]

I just got a new shocktech bolt because my old one broke (I dropped it.) but it won't fit my Xtra. It says clearly and I made sure of it that it fits the Xtra but it won't.

[druid]

how old is the XTra and what part of it doesn't fit?

Is the diameter of the bolt too big? Does the side-cocking knob not reach?

[spray and pray]

I got the wrong item sent to me......

Then thats not your fault.
