Opinions on barrel adapters?

What is an RVA, when I searched all I could find is "Rear velocity adjuster"

RVA is a rear velocity adjuster.

Correct. The RVA uses the drive spring to effect velocity. If you change the spring pressure you change how hard the hammer hits the valve and therefore the volume of air coming through it

In stock trim the tippmann blowbacks use a massive amount of air, between the stock barrel being roughly .7 and the barrel having an extremely short effective length (6ish inches) in order to get a paintball up to speed with all that you have to use a ton of air to compensate.
