I hope they thickened it up a reasonable bit.They just don't have the space to make them all..
Edit; What I'm getting in feedback on the reticle thickness, (and I've asked several people) is that the new one isn't "thicker" per se. It was described to me as being X amount of microns thicker, which didn't jibe with me, but it was clear it was thickened up in some manner to accommodate illumination. It should be more visible due to this. But this reticle at a glance is by no means thick.
There is liking a thin reticle and then there is unreasonably thin, which unfortunately seems to be the trend.
It's fair to assume most people buying the 3.3-18 version are not leaving it set at 18x all the time, otherwise they would've bought the 5.5-30, so making it properly usable at 3.3-8x would be excellent.
When Vortex first did the PST Gen2 line the 3-15 had a .052mil thick reticle vs .03mil i n the 5-25 and that suited the 3-15 perfectly.
When they switched to the EBR-7c they made them the same thickness which I think was a terrible idea.
In my opinion a super fine reticle in a 3-20ish scope adds absolutely nothing and just makes it less practical on mimimum magnification.
Long story short;
If the 3.3-18 has a .05mil thick reticle Burris will have nailed this scope, at least in my very noisy opinion.
