Im guna agree w/ bleach. It is only slightly better if you ask me, damage wise. If you want a scar to shoot faster go with the trispear. Honestly, most NX guns that say they preform on par with the regular ones (i.e. g36 valk, trispear, scar-l black, ak gold) they always have increased fire rate. So the scar-H is just stronger, but how much stronger can it already get?
Overall-Not worth it
