Hi everyone

I am hoping you guys and gals would be able to point me in he right direction. I have 2 Brno Zkk 602 rifles one is .375 and the other is .458Lott it was converted to the Lott. I have bought 2 NECG cz 550 peep sights for my rifles but unfortunately I did not get them in time to take to Zimbabwe with me and try them out. I have heard and read a few articles about the NECG peep sights not working too well with the factory front sight on the rifles so I know I'm going to have to buy some new front sights which is fine. Before I left Zimbabwe I checked my front sights and the dimensions. on my .375 it is a number 7 factory sight and on my .458 it is a number 8 factory sight. So
My question is with the rifles I have with these peep sights does anyone know the correct front sight I need to get from NECG for my rifles ? They have 6 different height front sights but they are 30 bucks a pop so I don't want to have to by all 6 to try and then have 5 left over once I find the correct one !! I have emailed NECG so will see what they say if they get back to me but if any of you guys out there could point me in e.g. Right direction I will be forever grateful !!

Cheers for now

Fire your rifle at 50 or 100yds and see where the group is.Then using the front sight calculator chart on the NECG web site you can easily determine how much of a higher or lower front sight you need.

Save yourself some grief, order the highest NECG gold faced partridge, install it and shoot and file it in to zero. Its the best sight picture out there and works great in any light.

Another option is Brownells used to sell and may still, a black plastic front sight with a round base that could be filed to any dovetail, they were an inch high with indentions ever couple of thousands that you could cut off...The are used to sight in rifles you cut them off until your rifle zeros, then measure them and order a carrosponding front sight. Somebody told me they aren't in the new catalog..They were an ingenious invention. They cost about a $1.50 for a dozen..

I tried the partridge sight and it did not work well with my rear sights-the sight picture was terrible.I don't know how it will work with a peep sight but I have my doubts to it being a good choice.I believe it would work with a square notch rear sight although I have not seen one on a big bore.

Peep and partridge are terrific combo.

Great idea, Ray. Many of the greats of yore recommended it too.
I have filed some shallow V's flat for that, and filed square notches into the centers of the flats.
Works great for holding Tennessee Elevations too.
I find it great for use with peeps too. Center the top of the post at the center of the aperture.
No problem!
It is my favorite too.

It takes skill and the right tool to file a rear sight for accurate aiming.

True. Get a gunsmith if you cannot do it yourself.

I've had Recknagel/NECG sights on my CZ and Brnos rifles for years. Rugged, easy to adjust and dependable, that's all I use.

They do shoot high with the factory-issued front sight. I'll give you metric measurements with approximate imperial translation.

The rear sight has a .5mm thread (.02"), which gives 4 half-turn adjustments for 1mm (.04") in height. On a 602 this translates in roughly 35mm change at 100m for every half-turn adjustment (1.5" at 110yd).

Set your rear sight 1mm high from the bottom (4 half-turns). Shoot a few groups at 100m (110yd), draw a line 50mm (2") above POA and and measure how much off you are in elevation (ideally, you'd want to end up about 50mm high at 100m, or 2" high at 110yd).

Whatever distance your group's center is off from the baseline, divide it by 140 and you'll have a good idea of how much difference you want in the front sight.

At this point it pays to do as suggested above, and try with a mockup sight.

On my rifles I use fiber optic sights. I cut them myself fom Recknagel/NECG Patridge front sights, that I order oversized. These end up much stronger than the fiber optic fronts available on the market, which all have tiny flimsy metal loops holding the fiber in place - and get damaged very easily.





I file and reshape the rear sight, to make it more streamlined and user friendly. As it comes out of the box it's full of very sharp corners, a knuckle-breaker...




Then I also file a small dovetail steel plate to cover the unsightly Express sights base slot

If I were using a peep sight I think that I might prefer a thin or small front sight.

Hi everyone

I can't thank you enough for all your help comments and advice I really like the idea of the partridge sight and especially with the fibre optic installed I have had an issue with a fibre optic sight on my first rifle a Ruger .458 win mag MkII. Again thank you all for all your advice and pictures when I get my rifles sorted out I will post pictures !!

The NECG or the Sourdough front sights work best with a peep sight as they were designed for peep sights, as its thin and square with a gold face and that is perfect combo for a round hole..

The partridge sight is not designed for a standard or shallow v, or barrel mounted sight. However I use them with shallow V barrel sights by fileing them down to give one a sight picture with the post flush with the top of the shallow V much like a pistol sight picture and its incredibly fast and accurate, much the same as a peep..The eye, like a peep sight, comes to target automatically.

My Texas Ranger grandfathers Win. rifles are all set up in this manner, it was the preferred rear sight and front sight method used by the Texas Rangers on the So. Texas Rio Grande border. He taught me this method from my childhood and I still prefer it to all other options..Those Ranger front sight were Silver coins cut square.

Just some options you might give a try, can't hurt. If you don't like it, at least you got a history lesson!!
