OK I went through my stable and tried out all the snipes I had - fire, rad, beam, elec, dark, archery. That's all except energy (I don't have a nrg blast toon) and psi (my psi is a sentinel which explains why i didn't remember the snipe in my above post). There's clearly something wrong with the assault rifle one. It is faster in quick mode than long snipe but not by much and it's waaaaay slower than the other quick snipes. I don't have numbers as that would have required recording but it'd be glaringly obvious to anyone who goes to compare them back to back. Oh and my AR is a corr so it's not just the blaster version.
