Re: Remmy R-25
Burris tactical rings would do just fine and be a fair price. Don't recall the name of them though.
At night, under lights- there is a lot of your problem. That's a situation that requires some very, very quality glass to get good visibility. Bushnell is decent- I own US Optics, NightForce and Bushnell; granted bushnell is NOT on the level of USO or NF, it's good for the price. But I wouldn't expect much in low, artificial light conditions.
A lot of guys get caught up on magnification- to the point of detriment. If you can afford NF, USO, S&B and the likes, then sure- go get your variable power with a top end higher than 20x. But you won't find anything in $300-$500 that is actually useable that high in anything but the clearest, brightest conditions. And even then it will look like you're watching television on a set from the 60's with a few tubes on the way out.
The common advise given to new shooters is to stick with something around 10x- that will get you out to 1000 yards... it isn't ideal for 1k, but it is capable. But, you should be focusing at 600 and in for a while anyway- a range which small errors don't result in total misses that you can't annylize without a good spotter to watch trace and splash- in other words, small errors still result in hits- poor hits, but still hits so you kno where they went. Once you are finding yourself outgrowing that scope, THEN look to something with higher magnification, more features... and be ready to spend more money. Glass has a sort of funny scale on value. In terms of tactical scopes there is usually little discernible difference between one that runs $75 and one that runs $200. Get into the $300-$700 range though and there is a HUGE difference. Then move up to $700-$1500 and the fades off a bit. Beyond that, the difference really are in the find details. So what I'm telling you is, try to start in the bottom of the $300-$700 range with something maxing out at 9-12x. Later on look at moving up to the top of that range, maybe up to $800 and make use of your new found practical range.
Oh and between the SS 3-9 and the weaver, the SS would be the better choice, but it's also $200 more... that's 200-240 rds of FGMM 168's you could have shot. However, if you don't buy before the price goes back up on the weaver it's only a $100 difference... making the SS a much more attractive option.
