General Information There are several suppliers of quality front and rear sights for single-shot black powder cartridge rifles. Since I’m often asked for a list of suppliers, my initial intent here is to identify them for the reader. But since this web site is focused on Miroku manufactured Browning or Winchester M1885 BPCRs, I will also provide specific details you may need to know when selecting sights for these rifles. When reading the following information, please keep in mind that I’ve only had direct experience with one supplier (AMT) therefore I’m not prepared to provide details on the overall quality, benefits and features of one supplier versus another. To make a final selection will require further research on your part. I suggest you run an Internet search and/or ask for references and recommendations on several of the Internet BPCR discussion forums.
Note, regardless of the supplier you choose, I strongly suggest selecting a vernier soule-type rear sight design, and a front sight with a spirit level which helps in reducing rifle cant when shooting at long range targets. A “soule” or “soule-type” sight is named after the inventor, John W. Soule, who was issued Patent No. 410,039 on August 27, 1889. It has the windage adjustment in the base of the sight rather than on the eyecup or peephole assembly. Adjusting the sight for windage on a “soule” sight moves the entire sight staff and eyecup.
Another excellent accessory is a selectable-aperture eyecup. Key to a clear and crisp sight image is using the correct aperture diameter to match the ambient light. Traditional eyecups with fixed aperture diameters work well, but a selectable-aperture eyecup is a real convenience when frequent adjustments are necessary for varying light conditions. Hadley-style selectable-aperture eyecups are available from Lee Shaver Gunsmithing, Davide Pedersoli, Montana Vintage Arms (MVA) and Kelley Sights. Lyman-style selectable eyecups are available from Kelley Sights and Baldwin Sights. For additional details refer to the article titled Selectable-Aperture Eyecups.
Merit Corp. offers several models of iris-type adjustable aperture eye discs, but as of this writing, due to the nontraditional design, they are not approved for NRA sanctioned BPCR silhouette matches. I do understand the Merit discs are permitted in BPCR long range target matches. The Merit #3 Adjustable Master Aperture eye disc is available directly from Merit or from Midway USA. Regardless of the brand or style of eyecup, just be sure that the threads on the mounting shaft match up with the threads in your rear sight elevator.
When purchasing a rear sight keep in mind that the sight base mounting holes must be of the proper size and spacing to match up with the holes in your receiver tang. The sight staff vertical detent angle should also match up with the tang angle of your rifle to ensure that the staff is close to perpendicular to the rifle bore line of sight. Several sight suppliers offer bases with adjustable detent angles. And don’t forget that the mounting screws must have the same threads as the drilled and tapped holes in the tang. Therefore, be sure the sight supplier fully understands the brand and style of rifle the sights will be mounted on.
Browning & Winchester BPCRs The following comments discuss specific details to keep in mind when purchasing sights. The tang angle is approximately 18 degrees and the two tang sight base mounting holes have a center-to-center spacing of 2.185”. The tang sight base screws should be 10-32x1/4”. Although all the sight suppliers are well aware of the original Browning BPCR tang and front sight requirements, some may not know that the more recent Winchester BPCRs are identical to the Browning’s. Therefore, if you’re purchasing a rear sight for a recent Miroku manufactured Winchester BPCR you may have to ask for one that fits a Browning BPCR.
Another area of concern is the front sight dovetail dimensions, especially when purchasing one of the Miroku manufactured limited series Winchester BPCR that comes without sights, but has a front sight dovetail. Sight suppliers may indicate that the correct dovetail width is 0.3925”, but I have accurately measured many of the original Browning’s and more current Winchester BPCRs and found the actual width is between 0.380” & 0.384”. Therefore, a 0.3925” wide dovetail can be made to fit relatively easily with some filing or by removing material from the base with emery cloth. The dovetails have standard 60-degree shoulders. By the way, the front sight should only be installed from right to left with the rifle pointing forward.
Finally, if you plan on purchasing an adjustable aperture disc, Hadley-style or Lyman-style selectable aperture eyecup for the AMT sights, the thread size and pitch must be 10-32.
