I can't say enough good things about the Vortex line of optics. I bought a Viper 6.5-20x44 MilDot back before the PST's were available, and have since purchased a 2.5-10x44 Mil/Mil, in addition to their awesome 8x28 R/T mini binos, SPARC Mini Red Dot, Strike Fire RDS, and Nomad 20-60x60 Spotting Scope.
The 6.5-20x44 has gone through some pretty extreme weather conditions, and held zero with exact & repeatable tracking. I used it for some load development on my 16" Grendel, and it's now on a 5.56 SPR and has been shot in -20 C/-4 F temps with high humidity, as well as 100 F in high humidity over the past year. That SPR/Scope combo has been able to hold .5 MOA-.75 MOA all along.
I think the 2.5-10x44 Viper PST is an ideal scope for most Grendel applications, since it is small, lightweight, has great knobs, reticle options, Mil/Mil or MOA/MOA clicks to match the reticle, illumination, zero-stop, excellent glass, and is a tough scope. I have it on my .260 Rem AR10 right now. I wrote a bit about it before the site was attacked, anticipating the release of the Viper PST's, and they have not disappointed.
I have a GRSC 1-4x on the Grendel, but I will put another 2.5-10x44 Viper PST on the Grendel in the future. You simply can't go wrong with the Viper PST's and I got that scope for under $600 from Scott at Liberty Optics, shipped.
