Randingo Posted January 20, 2018 Posted January 20, 2018 Several months ago, I picked up an H&R Buffalo Classic. The original sights were unimpressive with very little elevation adjustability. With elevation maxed out shots were 11 inches low. After some research and conversations with shooters who shoot these guns competitively, I purchased a new front sight from Lyman and a new Smith Enterprises Buckhorn Extra Long Range rear sight from Buffalo Arms Co. Front sight arrived first and was mounted without difficulty. The rear arrived and I was initially impressed with it. Sight appeared to be very well made. Tang pops up and the sliding sight works smooth. The issue is that when mounted to the barrel, it sits canted to the right approximately 12 degrees. I removed and remounted it several times with the same outcome every time. Thinking that the mounting holes in the barrel may be drilled incorrectly I took it to my gunsmith. He assured me that the mounting holes are correct. The issue is with the sight and the mounting holes which are not centered in the sight. I contacted Buffalo Arms and explained this to them and asked if I could return the sight for another. There response was no. I was told that because I had mounted the sight that it was considered used and could not be returned. Three follow up phone calls all produced the same response. (This has been resolved). Thanks for all the help. I have amended this post to reflect my lack of Knowledge and not Buffalo Arms service. Did not intend to offend, was just seeking help. Thank You!!!
John Boy Posted January 20, 2018 Posted January 20, 2018 Quote My options are to have the sight milled ($75.00) or use 4 aluminum shims from a beer can. Rindingo, your options are correct and not uncommon with any rear sight or tang peep / vernier sight. You have an option to mount the sight as is and correct the plumb with the windage adjustment on the sight for the 12 degrees I mount tang sights on nearly all the rifles I own and each one needs to be shimmed or the sight base milled to be fitted plum to the front sight. It is No Big Deal to do Yes, I agree with Buffalo Arms - they do not accept returns of mounted sights plus if they did and sent you a new one ... it too would have to be either milled or shimmed to be plumb to the front sight
irish ike, SASS #43615 Posted January 20, 2018 Posted January 20, 2018 I have two very expensive vernier sites. When I checked them for vertical square to the barrel, site , breech they both needed to be shimmed. The installation instructions said to check for square and shim as necessary using paper or metal.

Thanks for the reply. I am saving for a Shilo Sharps and hope I don't have this issue ever again. Thanks!!!

They’ll mount it on for you free and it’ll be setup perfectly.
The Original Lumpy Gritz Posted January 20, 2018 Posted January 20, 2018 BACO clearly states that if you mount it-You keep it. The shim deal is very common. I had to shim both of my Shiloh's MVA tang sights, and have done the same for others. Go buy a set of feeler gauges, and use the 'blade' that works for you. They are easy to trim with tin-snips. BTW-It's NOT the fault of the sight-It's the fault of sloppy QC when the rifle was built, and how the holes were drilled. Very common issue with this brand of rifle. OLG

John Boy Posted January 20, 2018 Posted January 20, 2018 Randingo - if you plan to shoot your Shiloh any distance more than 600yds, ask Shiloh to mount the sight with a 3 4 degree drift on the left. This will compensate for gyro bullet drift shooting long range when the sight is mounted at zero degree windage

John Boy Posted January 20, 2018 Posted January 20, 2018 Rindango - since your Shiloh is a future purchase and you'll be mounting the Smith sight on your H&R - read this how to tread for getting the sight plumb ... http://bpcr.net/forum/viewtopic.php?t=2616 And if you are a diabetic, the plastic strips from your meter readings are perfect shims
Dirty Low Down sass 23492 Posted January 20, 2018 Posted January 20, 2018 Pair o snips & a empty coke can been known to go a long ways-----Don't ask how I know!!!

That 'can' is only .001-.002" thick. Many times more than that is needed, and it's best not to 'stack' shims. That is why I say buy a flat feeler gauge set, and use the 'leafs' from it for your shims. Respectfully, OLG

Chili Ron Posted January 20, 2018 Posted January 20, 2018 Howdy, One option is to go to the Dollar store and buy a cheap set of feeler gauges. Those steel leafs make great shims. Thichness is often marked right on em. My local dollar store sells em for.....a DOLLAR. And if anyone hasn't shimmed a sight or scope they arent really shooters..... Drift due to spinning bullets, how cool is that? Best CR
The Original Lumpy Gritz Posted January 20, 2018 Posted January 20, 2018 11 minutes ago, Randingo said: I like it. Will do!! Cut the shim to the full length of the sight base. You can use cold blue to color the shim, to 'hide' it somewhat. The spin 'drift' will change some from different bullet types and bullet speed. I set my Shiloh's up with a no-wind 'zero' at 500yds, with the bullet/load that shoots the best. That is, the rear Soule tang sight is centered at '0' at that distance. Yes-I must move the front sight within the dovetail some, to archive this setting. I plum the rear tang sight at 90* side to side, and when that is set. I will angle the staff forward 2-3*. This helps in a clearer sight picture at the longer ranges. Good luck, OLG
Dirty Low Down sass 23492 Posted January 21, 2018 Posted January 21, 2018 O.K. Lumpy-----ya got me sold ---when spring gets here & I get back to getting out & playing w/ my toys again the coke cans come out & feeler gauges go in------Good excuse to go shoot off couple hundred rounds!!!!----HEE HEE !!!!
Mud Marine,SASS#54686 Life Posted January 21, 2018 Posted January 21, 2018 I believe that I should mention that I have been a customer of BACO since its founding. They have always provided the most superlative service of any merchant of any kind with which I have had any experience.
Kid Rich Posted January 21, 2018 Posted January 21, 2018 I have to agree with that. I called them and they gave me a good starting place for loads for my 45/90, bullet weight powder etc. kR
Mud Marine,SASS#54686 Life Posted January 21, 2018 Posted January 21, 2018 Dave Gullo, the owner, uses a .45-90 for BPCR. He has won every type of international and USA long range black powder rifle championship with with that rifle. I imagine that if anyone knows about everything about that rifle, it would be Dave. Like most champions in sports, Dave is happy to provide others with the advice they need to be better competitors.

As I said this was my first experience with this type of sight and with Buffalo Arms. That is why I asked for help. There is a tremendous amount of experience and knowledge within the membership of this forum. I thank you for sharing it with me. To Buffalo Arms: My apologies. I should not have jumped to conclusions. With the help provided me here, the sight is mounted correctly and functions as expected. Thank you for providing such outstanding products to the shooting community.
