Perhaps this thread might obtain better response in GUNSMITHING forum, but the essence of the problem to be solved pertains to recoil.

I seek a particular configuration of adjustable aperture sight assembly. I am creating a rifle for which I will frequently change loads, requiring sufficient precision of adjustment that I can "dial" or "click" in adjustment to obtain repeatable changes in point of impact. MVA's #134 mid-range Soule sight has what I seek. BUT recoil will be so severe with some loads that a sight mounted on tang is unsatisfactory.

I did a preliminary search in my reference library. The only sight assemblies that might achieve results wanted are M1/M14 National Match sights or a match sight (Parker Hale??) intended for competition SMLE No. 4s. Not only am I uncertain whether any of these receiver-mounted sights can be adapted - or the flat top of barrel-receiver on my rifle adapted - but I have no idea whether these kinds of sights have the repeatability and precision of MVA's.

I need to identify more possible sight assemblies. A little help?

Yes,

Go to the Brownells catalog, and look up the Williams Sight #55. It comes in precision and hunting styles. Get the precision style. Most rifle actions more than ten years old will have holes already drilled on the side for direct mounting of these sights. If not, have your gunsmith do it for you.

I'm having difficulty locating the #55. I checked my Brownell's catalog #60 and Williams' web site. I downloaded their catalog and searched every page. I did not detect a #55. The target sights whose blurb I read do not approach the repeatable precision of MVA's sights. Of course, considering price differences, it is unreasonable to expect comparable quality or manufacture.

I've been considering the problem from a slightly skewed perspective. Since the #134 does the job - it is recoil that concerns me - would drilling & tapping tang to allow the MVA to be mounted farther from shooter's eye solve the problem? MVA offers at least two Hadley aperture disks having multiple sighting holes - a larger aperture compensating for excessive distance of aperture from eye? Rifle and sight are not intended for target work. The function of the sight's precision pertains to being able to used [three] different loads having different points of impact, my being able to dial- or click-in any without needing to resight. I have a friend whose hobby is squeezing the last drops of accuracy from his BPCR rifles. He experiments with loads constantly. MVA and C. Sharps Soule-type tang-mounted vernier sights allow him to dial in any tested loading point of impact. And his range testing begins at 300 meters.

Your idea would have merit were precision inherent in the sight. That's my key. The whole purpose for my scratching around is to avoid having to resight to return to a previous point of impact. Precision as I describe is the reason that, for example, NM M1 sight assemblies are so much more expensive than G.I. issue.

The tang mount is not a great idea. You can get very repeatable sights from Creedmoor, Champion's Choice.

Warner rear sights will get you more accuracy than you are capable of using.

Please furnish links to these sights.

Do not forget to define your purpose frst. If your rifle is not capable enough accuracy to justify sights that can be adjusted in 1/4 MOA or 1/8 MOA increments; it might be a waste of money to get sights like these. Of course, you can always sell them for not much under what you paid for them. Creedmoor
