CGH: Riton Scopes

CA Guns & Hunting: Shooting is fun, accurate with Riton RT-S Mod 5 4-16x50 scope

BY STEVE COMUS/Cal. Guns & Hunting Guns EditorPublished: Jul 05, 2019

Shooting is always fun. It is even more fun when using really good gear that delivers what it says it will, and more.

After checking out the Riton RT-S Mod 7 1-8x28R-H scope (see the previous issue of WON where that effort was reported), I next took the Riton RT-S Mod 5 4-16x50 scope for a ride.

There was no question about the quality and performance of the model RT-S Mod 7 1-8x28R-H, so I had no trepidation with a model down a notch or so on their hierarchy – one with a higher variable range, which is more in line with what most hunters use for general hunting these days.

THE RITON SCOPE worked great atop author’s Remington 700 in 7mm Remington Magnum.

I was impressed enough with how precise and positive the adjustments were on the 1-8x model that I figured I would put the RT-S Mod 5 4-16x50 on a really accurate hunting rifle – a model that might be used for general hunting pretty much anywhere across the land, capable of hitting from near to far. I thought that to be able to judge the precision of the scope adjustments, I needed a rifle accurate enough to make such measurements predictably.

To give the RT-S Mod 5 4-16x50 scope a ride, I chose a first year (1962) Remington Model 700 BDL in 7mm Remington Magnum (also the first year for that cartridge).

I have two first year 700s, one a BDL (used for this effort) and an ADL. They are both hair-splittingly accurate when fed good ammo and handled properly (sometimes I suspect those rifles think they are benchrest rigs rather than hunting rigs, although both have taken many big game animals at various distances over the years). The BDL has a 23½-inch stainless steel barrel and the ADL has a 23½-inch barrel that doesn’t say “stainless steel” as does the BDL. Later 700 magnums sported 24-inch barrels, but the first ones didn’t. I once asked the folks at Remington about why the difference, but don’t remember the answer offhand. Whatever it was, it wasn’t memorable. And what’s a half-inch of barrel among friends when a rifle is incredibly accurate? Some folks in Gundom like to focus on minutia, though.

Reminds me of a time when I was chatting with Tim McCormack from the Remington Custom Shop and we were looking at some 700s during the 80s or 90s (foggy on the year) when I noticed that the left side of the receiver was no longer drilled and tapped at the factory for an aperture sight. He chuckled and noted that they had stopped doing those threaded holes several years earlier, but that in all that time, I was the only person he had heard of who even noticed. I like aperture sights, barrel sights, scopes – all of ‘em. Back to the Riton scope.

After mounting the scope in Riton’s RT-M 30mm MID rings, I verified that it was more or less shooting where I was looking by having it put a hole in the target on the vertical and about 1½ inches low at 25 yards.

Then I moved the target to 100 yards and fired one shot. The hole was roughly 1¾ inches to the right and 1¼ inches low. Click adjustments are 1/4 MOA (four per inch).

Even though calculations would indicate seven clicks left, I decided to do six, just for kicks and giggles. Sure ‘nuff, the next shot went 1½ inches to the left of the previous shot (but also was about a caliber lower (probably pilot error).

THE RITON 4-16 scope is shown here in the Riton rings used in the workout. Everything worked great.

That mean the last hole was roughly 1½ inches low and a quarter to half-inch to the right, more or less (at 100 yards I have problems being more precise with old eyes, although measurements after shooting verified the distances between were pretty much dead-on). I thought, okay, let’s go left slightly past where I want to go and then come back for fine-tuning. Also, I wanted to ease the impact up a nudge to see what a double adjustment would do.

So, I gave it five clicks left and three clicks up. Yep. That bullet hole was ¾-inch low and ½-inch left. I wanted the next shot to be one inch low, dead-on. That meant one click down and two right.

Bang! Bullet cut the vertical line right at one inch low from dead center of the ¾-inch paster. Very nice. I then wanted to go up, past the center of the bull so that the next bullet would go one inch high from dead center on the paster. I clicked eight clicks up and popped off a round. A millimeter or so shy of exactly an inch high, dead on. Must be old eyes making the difference.

I was getting bored, (when great gear behaves perfectly, boring is good), so I clicked down four clicks and went for it. It wasn’t dead center in the ¾-inch paster, but close enough for government work (the upper edge of the bullet hole cut dead center on the ¾-inch paster). To put it in perspective, that hit would have been in the eye of a fox or bobcat at 100 yards. The point is that the scope “walked” the points of impact at will, right, left, up and down – and it did it with precision. Very nice.

The reticle in this scope is what Riton calls its hunting reticle. It is a modified plex arrangement with hash marks below and to the right and left of the crosshairs to allow for precise holds in wind, as well as at extended ranges.

Also, the reticle is in the second focal plane, which means it appears to be the same size regardless of magnification setting. Average eye relief is 4.4 inches (very nice for a hunting scope). Total internal adjustment is 80 MOA.

The 30mm main tube is made of 6061 aircraft grade aluminum. The scope is 12 inches long and weighs 23 ounces.

There are three turrets on the scope. Two (top and right) are capped zero resettable turrets, while the third on the left is to adjust for parallax. Parallax adjustment becomes more important the farther out one shoots, because it minimizes the effects of the eye not being exactly in the same place for every shot. Most hunting scopes that do not have parallax adjustment have their parallax setting for 100 yards or 100 meters. Some airgun scopes are parallax-free at 25 yards.

It is difficult to relay how crisp, bright and high definition a scope is to someone else. It is the kind of thing that has to be experienced to be fully appreciated. I was impressed with the resolution, color fidelity and other optical characteristics of this scope. The best way to describe it is to relay what I experienced when it took it out into the world to try some random shots at various distances, etc.

Hitting targets, both short and long, was predictably smooth and without incident – put the crosshairs or hash marks in the right spot and hit.

While playing with the rig, however, I did use a rangefinder and discovered that with the scope set at 16x, I could discern the pattern in chicken wire at 334 yards, individual saguaro cactus spines at 595 yards and a rabbit in the open shade under a bush at 719 yards.

When a scope works in the bright sunlight and in the shade, it pretty well sums it up. This scope is hunt-ready as soon as it is mounted on a rifle and sighted in.

There is really not much more to say. This scope has it all and does it all very precisely. For most hunting, one would be hard-pressed to find a scope that could match or surpass it. And that’s saying a lot.
