I posted this in the lever rifles section, but haven't got much response, so I thought I'd post it again here.
I picked up a new USRAC Model 1886 Extra Light Rifle a couple years ago that has spent far too much time in my safe and not enough time in the field. I've decided to get it into hunting trim by adding a proper recoil pad and a decent receiver aperture sight. The front sight is a very nice gold/brass bead that shows up well, so I don't know if I need to replace that. But the semi-buckhorn rear sight is not good enough.
This is not a rifle I have any interest in mounting a scope on. It's too pretty and too traditional a rifle for that sort of nonsense. My eyes ain't what they used to be, but I can still use open sights and hit what I'm aiming at out to 100 yards, but this rifle is drilled and tapped for a receiver sight. I think I could do a lot better with a good receiver sight and perhaps a globe-type front sight, but I have zero experience with aperture sights other than the Marbles Tang Sight on one of my cowboy carbines.
Any opinions on what receiver sight I should mount on this rifle would be greatly appreciated. Lyman has a version of their M66 that is specifically designed for the USRAC/Browning 86's. I have no experience with Williams receiver sights. I've heard that the XS ghost ring sight is popular, but I'm not sure if it's going to give me the accuracy I want at 150 yards?
Also, my only globe front sight experience is with a repro 1873 sporting rifle, and I like it, but don't know if it gives much of an advantage over a standard post-and-bead at the ranges I've used it (out to 150 yds or so). Is it worth the trouble of removing the post/bead on my 1886 ELR and replacing it with a globe sight, given the likelihood that this rifle will never be shot at an animal more than 150 yards away?
DocRocket:
Just chiming in to offer a couple of suggestions and cmts.
1. I've a Browning 1886 SRC that I'm fond of. I ended up with a Marble tang aperture and a custom foresight that consists of a wide blade with a large brass bead inset on a shelf. Offers a fast visible sight picture for aging eyes without the beads tendency to shoot away from the light.
I use orignal LYMAN 66 and a REDFIELD SOURDOUGH on an original WInchester 71, but the modern iteration of the Marble tang seemed adequate for the Japanese Brownings I have in 45/70 and 357. I use original Lyman and Redfield Sourdoughs on my 92's except for a Japanese Browning 92 which also has the tang aperture since it's used occasionally in SASS.
Tang Apertures are perhaps the optimal aperture sight as far as fast sight acquisition, but can be a problem with a heavy recoiling light weight rifle if the eye is too close to the tang. That being said, I tend to prefer a receiver sight and prefer earlier iterations of the Lymans on original guns since I think they just look better. Don't mind a current Lyman on the Japanese Repro's though. Just a matter of taste.
2. I've never heard of a problem with the grand old Williams Fool Proof aperture and used to use them exclusively back in the fifties and sixties on a variety of Marlin 336's and 39A's. Mebbe steel and alloy will wear them out, but I don't know anyone personally who fiddles much with the sight adjustment after zero. As a matter of taste, I just prefer the look of the older Lyman's to the Williams FP or the current Lyman's.
3. The XS sights are viable options, but, personally, I discount them for the same reason I discount 'scopes on a saddle gun---they just don't look right to me.
4. As has been said before, stay away from the globe foresights in the hunting field. Marvellous sights for their intended purpose when there is good light. Hard to beat the old REDFIELD LYMAN SOURDOUGH---they were made for a while after Redfield disconintued them by BURRUSS and are, or were, the last time I looked, offered by NECG's. My foresight was visible in the Maine woods on my WInchester 71 until after target discrimination was not viable.
5. Don't discount the ROCKY MOUNTAIN BUCKHORN sight if you're shooting fast and close---say for hogs. I always dismissed the buckhorn because "it obscured the target" in the common wisdom when I was growing up. I learned from SASS just how fast and accurate the Buckhorn can be when it's used as a "sorta, half-arsed aperture." Wouldn't be my choice for precision shooting, but for hogs in the SE, it can be a useful sight on a 45/70 Lever.
Hope this is useful.
