Ok,
So I need an affordable scope for my SPR-ish/3-gun build (18" WOA barrel).  I currently only have access to a 200 yard range.  This will be primarily for casual target shooting with the possibility of shooting 3-gun (if I ever get the time, etc.).  I'm limited to Amazon as I have a $200 gift card there.  So, I figure add another $200 and I can get something pretty nice (yes I know "pretty nice" is all relative).  I do want a 30mm tube though.  So, I'm thinking.....

Burris 4.5-14 MTAC
Vortex Viper PST 1-4
Vortex Viper HS-T 4-16
Vortex HS 2.5-10x44

Other recommendations?

For 3 gun, you really want a true, or close to true, 1x magnification at the lower end.
You only have one listed suitable optic out of those, the PST 1-4x.  You might also consider the Burris 1-4x MTAC..
1-6x is certainly 'nice' to have, but generally not needed for most typical 3 gun matches, unless  real outlier, IMO - I shoot regularly between 15-300yards in 3 guns, and while I do run a 1-6x (not < $400), I could still make do with a 1-4x.

ETA - random quick poking around on amazon:

Ok,
Outside of 3-gun (I've been reflecting and come to the realization that I'll probably never get the time etc for 3-gun), what do you recommend?  How's the HST 4-16?
