Re: Weaver FFP 3-15 or Vortex Viper PST FFP 4-16
If it's subjective opinions you want, you should get plenty. I bet almost all opinions you get will be from someone who has either one of these or the other. I don't think there are many, if any, that have both of these scopes at this time.
I have the PST 4-16 FFP and I can tell you this is not a frail scope and as hydro556 says the turrets are really nice. I would add the reticle is pretty decent also.
Both scopes will be good on weight, the PST slightly better I think.
The biggest differences as far as I can tell is going to be the reticle and zero stop on the PST, and the glass in the Weaver would likely be better to my eye though I haven't looked through one. I have a Nitrex scope and I am basing that last statement on the assumption that the Weaver Tactical glass will be like the Nitrex glass which is very good.
The Weaver has an older style reticle that looks almost exactly like my Falcon Menace reticle except that the mildots have an open center. The PST reticle has hash marks at the mil and half mil marks and are numbered every 2 mils. I don't see how anyone could have a gripe about the PST reticle for tactical shooting.
Some will say they like the older style better. I'm not sure how much emotion can be found in that point of view but having both, and liking both, I like the PST better.
Also, the illumination on the Weaver has the option to choose between red and green while the PST has red illumination.
The turrets will also be different as the Weaver Tactical has the locking turrets (like my Nitrex) as compared to the more standard PST turrets which, again, are very positive. I doubt the Weaver turrets will have the positive feel of the PST turrets but I haven't tried them first hand. My guess is they will be similar to my Nitrex locking turrets.
In the durability department neither of these scopes have been out long enough to prove themselves. I think the PST may have an advantage in following the Razor and being able to borrow from the engineering from it's bigger brother.
A couple more points to consider:
The PST can likely be counted on to have a straight reticle and accurate adjustments after having 2 tries at the current production model. This may be a moot point if Weaver nailed it on the first try.
Warranties - the PST cannot be beat. I don't know the details of the Weaver warranty to be honest.
I would watch for a report from jrob300 for a better breakdown.
So, it's all in what you want. We are lucky to have them both as options at that price point. Unlike many in this forum it won't hurt my feelings one bit if you chose the one I don't have. Freaking communists.
