Mossy Oak 22 In. Crossbow Bolt

Very economical but straight shooting. Test them by rolling on a hard flat table or quartz counter top. If not true take the back for exchange. However I bought a dozen and none had to be returned. Shoots much truer than my Carbon Express, Ten Point and Parker bolts/arrows. Some reviews slam them for not being durable but without proof. Mine have been as durable as any and much more durable and resilient for reshooting than my 10 Point aluminum arrows. The vanes are fetched in a strong spiral to make arrow spin and fly straighter. My Ten Points have same spiral but not as severe. Both these spiraled arrow brands shoot straighter than my straight fetched arrows, the Parkers and Carbon Express. I have read where to much angle in the vanes can be counter productive. But I now prefer them. I would like to know what the inside diameter of the arrow barrel is at the knock to buy some lighted knocks. My Parkers are 0.300?. This Mossy Oak arrow is 22" crossbow knocked with+/- 0.003" run out on shaft.
