I just my Rigby back from JJ today and I am very happy. He built a red dot mount using the thumbscrew that is torqued down using a cartridge case.. However, to keep from cutting into my rifle, he built a new rear sight piece which provides the mounting surface for the red dot mount. It contains a rear sight that can be used as normal if the red dot is removed. Also, the rifle can be put back to 100% factory by simply drifting off this rear sight piece and replacing it with the factory one standing and three folding leaf rear sight. Quite ingenious really.

Why not use a Trijicon RMR instead? Then you don't need to worry about detachable mounts as the RMR is really better than iron sights.Has anyone actually put a Trijicon SRO on their double? What moa did you select? I am going to put one on my new Verney 375 flanged magnum o/u. Will be using an RM57 detachable mount so i can quickly revert to open sights, but this will require milling two small indents on the sides of the quarter rib.
Massaro mentioned using a 1 MOA dot. I personally think a 3 or even 4 MOA dot would be quicker and more appropriate for a double used at under 100 yards. JMO
Theres not a ton on here that I feel I can contribute a lot to (yet) but this is definitely one. I'd recommend a smaller dot than you think you need. When the brightness is turned up high they're plenty large and fast. But you can turn them down for precision, further shots.
I shoot a 1moa red dot on a .223 AR in competition. On close targets that are only about speed, I turn it up. But i can turn it down to reliably get accurate hits out to 600yards on the clock. Alternatively, the larger dot sizes (3 or 4 moa) dont get precise enough for my liking even when turned down.
It's also my personal opinion that these moa ratings arent accurate. I think my "1moa" when turned down even is still at least 2moa and probably closer to 3, based on target size when I zero the optic off a bench at 100yds
Just speculating now....Yesterday was spent at the range with the Ruger No1 375 H&H with Leica 1-6.3x24 red dot and the Verney o/u 375 flanged double with open sights. Shooting 300 grain Hornady DGS with 68 grains 365 in the Flanged and 70 grains in the H&H. The results after some 25 shots has changed my view on all this Red dot debate. Firstly the Verney is a perfect fit, light, balanced and every mount brings up the same sight picture. A small departure from the story but honestly guys such a thing is worth every hard saved cent. Anyway, static shots with the Ruger on 6.3 power at 50m were easily all in the 50mm black, whereas the Verney were large grapefruit, say 90mm. About 6 rounds through the Ruger and 8 through the Verney, switching between barrels. Regulation on the Verney at this distance with either Woodleighs or Hornady DGS is about 35mm. No surprises so far. Then we switched to charging lion target, engaging from about 35m in. The Ruger red dot shots on 1 power now were all oner the place and easily 200mm. Quite hard to acquire the target as it was set up to come in on a curve. If this were a real lion the shooter would probably be dead. The Verney, however, now transformed into the Cinderella and shot after shot was in 75mm, 4 in the black 50mm. Could it be, as I think is the case, that this was as much down to perfect instinctive alignment as to sighting? Deal lion every time.
In summary, the Verney ir perfectly capable of good shot on DG, buff in particular at least out to 50m and although a dot would undoubtedly reduce the hit radius, it is enough without. And if it comes, a good fitting open sight is way better. So fo me, there will be no dot sight on my Verney and my 65 year old eyes are far better aided by good fit than technology. The Ruger will remain the longer shot PG choice.
The distance between the dot and your eye will account for very little change in dot size.Red dot sights specify the size of the dot as 1 MOA, 3.25 MOA, etc., But it would seem to me that the size of the dot in MOA, since it is projected on a glass in the device, not into the target, would be a function of the distance the glass screen is from the shooters eye. In the case of a red dot mounted on a handgun this distance could be close to 2 feet. In the case of the RMR on the Blaser S2 above, this distance would be measured in inches. Am I missing something or should the distance between the shooter's eye and the red dot sight be taken into consideration when choosing a red dot sight?
