Can anyone tell me what section the replacement springs were from ARH? I have a 127 at home with a square section spring. Now it may be an Ox (!) but it cocks very nicely (no wrestling matches) and sits low 11's fpe with nice sensible recoil (I can see pellet flight when using Accupells). So , I'm not planning on changing it (I have a stock 127 spring in my stock of springs), I'm just curious - either someone did a good job with an Ox (even the fit to guide is sublime) or it's someone else's aftermarket alternative.
