Front Sight

I have a couple of questions about front sights.  I see that they come in different heights from (.500 to .850) the bottom of the dovetail to the center of the aperture.  What height should I get or how do I know what height I need? 

Happy New Year and thanks for your time,

If it can be done without too much problem, I was planning on putting both a tang and barrel mounted sight on it.

I am assuming that your barrel has some taper to it.
you need to know the distance from the center of the bore to the top of the front sight that you are planning on using and thecenter of the bore to the top of the bbl mounted rear sight that you are planning on using so you will need ti figure out what distance that will be from the front sight - from there you need to know what the trajectory of your bullet is and what distance you will be shooting at - from there it is just simple trigomometry.  If you need more details I will need more info.   
Good luck.

rimfire - The rifle is a Winchester 1885 Highwall 30” barrel no sight BPCR 45-90.  I just received and email from Lee Shaver's and he said he wouldn't suggest putting a tang and flip-up barrel sight on the gun - it causes too many problems.

Thanks,
Greg

Orginally I was thinking about getting a Shaver's Long Range Buffalo, Shaver .450" D.T. Spirit Levelw/Insert Front Sight, and a buckhorn (ladder).  Now, with everyones great input I'm down to Shaver's Long Range Buffalo, Shaver .450" D.T. Spirit Levelw/Insert Front Sight.  What do you think of this combination.

The long range tang is a good choice if you are going to be shooting any distance - the same with the spirit level front - to cut down on any tendency to cant.  I don't have any Shaver sights but do know that he has an excellent reputation.  Let us know how it all works out.

Greg,

Unless they put a different size dovetail from what they used to use on the BPCR's, I believe it is a 3/8 dovetail (.375 DT) not the .450 which is a shiloh rifle size. I have one of the original Browning BPCR sights on one of my rifles and it is a .375 dovetail

Wait until you get the rifle in hand before you order or ask Texasmac (I believe you said you were getting a rifle from him) what the front dovetail (D.T.) size is.

I tried to give you a shout Saturday but you weren't home.

regards
dave cook

On the height.  With a tang sight you can accommodate most front sight heights. However I often see someone with a poor fitting set up.

I set up to have the head position I want on the rifles comb.  Set the tang sight to suit.  Then keeping that tang sight setting zero the rifle at it's most likely distance using a temporary front sight, Piece of cardboard or plastic duct taped or hose clamped on the muzzle, cut back to zero the gun. Then measure the proper height and have the front sight made to suit.

Greg,

I’ll jump in here with some comments.  I understand the current Winchester BPCR Creedmoor model that does come with sights has the correct sight dimensions for handling any range out to 1000 yds. as does the original Browning Creedmoor.  Although some folks prefer sights from suppliers other than AMT (the Browning and Winchester sight manufacturer), Browning/Winchester did their homework on the correct size (height) of sights.  The soule tang sight ladder has an adjustable range of 0 to 2.5” with the lowest setting placing the aperture hole approximately 2” above the rear tang.  The 2.5" of adjustment results in approximately 250 minutes of angle (MOA). The center of the front spirit level sight is approximately 0.7” above the bottom of the dovetail.  You might consider using these dimensions as guidelines.  The Winchester does have a standard 3/8” dovetail for the front sight.  And be sure to request the tang sights with the correct base hole spacing to fit a Browning or Winchester.

When purchasing a front sight, you will have an option of a fixed or windage adjustable sight.  Although most soule-type rear sights are adjustable for windage, shooting out to 1000 yds may require the addition of a windage adjustable front sight.

By the way, I concur with the suggestion that you also purchase a Hadley-type selectable aperture rear sight cup, which allows for easy aperture hole size selection based on prevailing light conditions.  Just make sure you get one with screw threads to match the rear sight.

To check out the sights that came on all the Browning’s and some of the current Winchester Creedmoor’s, click on following link. (You need to Login or Register to view media files and links)

In case you are interested I do have a brand new AMT full windage set available.  You’ll note that AMT currently gets $560.  I’m asking $450.  It comes in a plastic storage box, has the three eyecups and a sight card with 8 inserts.  By the way, the rear sight staff is tight with no fore or aft movement, which is one of the complaints Browning rifle owners had.  The rear sight has the correct hole spacing for a Browning or Winchester.  If you do purchase a 30” barrel rifle from me and the sight set, I’ll even mount the front sight for you.  The tang sight is very easy to mount and remove with the two screws that come with the sight.  I should also mention that the top of the rear tang sight base has "BROWNING" stamped on it

Greg,

I forgot to add, if you do visit the AMT web page, be sure to click on the link in the page to the specification information. The specification information for either the Winchester (Modern Remake) or the Browning will provide you with additional guidelines when purchasing sights, even if you decide not to go with AMT.

Thing about windage front sights is you can zero the rifle match day using the front sight, rear remains at '0"  Once the match starts You crank windage on or off  using the rear and less likely to get "lost"  If conditons change or fool you go back to zero without any calculation.


This is real important when adjusting during a timed relay and the primary reason front sights are adjustable.
