I was just comparing products between the standard 105 and the ones with all the upgrades when i noticed the standard one had the right 1:8 twist rate, but the other one claims to have a 1:10. As far as im aware 1:10 is too slow for almost all 5.45x39 ammo available so im wondering if this is just a typo or is PSA has something else in mind.
I already saw someone asked this same question on the product page but it has no answers.
