so.. is this true about the Match Barrel Attachment?

If we equip Match Barrel, shouldn't we use the Rapid fire module? because it is unnecessary?

Match barrel reduces spread and apparently the rate of spread increasing. Rapidfire increases the rate of fire and so increases the speed of spread increasing. ADS and laser reduce spread dramatically so its virtually a non issue. :/

Muzzle brake reduces recoil, which is great on the higher recoil weapons.
