Hey Gang,

I'm about to buy these Ancient Spirits Kadiak limbs.
Only problem is they have some minor cracks along the limb-bolt and pin holes.
Do you think they're gonna widen or weaken the limbs?

I dont think they will hurt anything at all I had several AS bows and this was a common thing on everyone. It may be caused by cranking the lims down to tight.

It is OK.

Wow!
Not even 20 minutes  

I'd use some thinned-out superglue and massage it into the cracks, but those should be OK.

That's a fairly common occurrence on many takedown bows.  Doesn't seem to affect them.
