When sighting in my Troy flip up, back up sight, I noticed I had to dial in a lot of windage on the rear sight. I took a closer look at the front sight and discovered that it’s way off center in relation to the rail and barrel. It appears that’s the way it’s designed. Like the flip up part is off to one side and not dead center on the rail. Is it supposed to be like that? Will it make a difference in terms of accuracy?
It happens. Would not get too overly concerned about it since from what I have seen it will happen. i lucked out with mine BUIS on my latest BCM upper not needed to dial anything to get a 25 yard zero. But on other guns have had to crank the rear way over.
Now that said, if the gun is zeroed, then it should not affect the accuracy of the rifle.
Mine are like that too. Although I love the Troy BUIS, I might pick up a set from another manufacturer to try out.
Alright cool, thanks. Does that mean that with a 50-yard zero, the windage will be way off at other distances?
I understand that for elevation, due to gravity, the POA and POI are the same at two points: when the bullet is on its way up, and again on its way down. But windage is a straight line (forget about wind for a sec). So if POA and POI are the same for windage at 50 meters, but the sight line is a diagonal path off to one side, then POA and POI will never cross paths again at any other distance, as far as windage is concerned. Right? Because instead of two parallel lines, the sight line and bullet’s flight path are angled to each other and only intersect at one point (wherever you decide to zero). Instead of the sight line being over the barrel, or centered around it’s axis, the sight line is now canted off-center and angled to correspond to POI at one specific distance. So I’ll wind up having to figure out and memorize where to hold the sights for left/right travel at various distances?
Or maybe I don’t understand how it works?
You’ll be fine.
May notice something at 300+, but you could easily iron that out by zeroing at actual distance, or at least at 100+.
I’ve seen this to be common with the troy buis. I’ve had to do that on two of my guns using them. Thinking about trying the Magpul pro sights and seeing if I have the same issue.
Yep. Garbage sights. If I had a dime for every windage with TROY sights thread I’ve seen… I’d have like Tree Fiddy.
lol yeah that’s what I figured. I am looking at alternatives.
I’d think that for all the money you spend, Noveske would take a look at the sights before they ship a rifle out… Or at least switch over to a better supplier.
You are looking at it wrong. Consider that adjusting the sights is bringing them parrallel with the trajectory in regards to windage.
What are you sights mounted to? Is it a free float rail?
Consider that if the centerline (C/L) of the barrel and the centerline of the rail are not concentric., even by just a few .001"s of an inch at the barrel nut, it means that the end of the rail is out even more at the end that the front sight is mounted to. Another variable is the C/L of the receiver being out to the C/L of the barrel.
My point is that if everything isn’t perfect, there will be need to make sight adjustments
Agreed. That’s the whole point of zeroing the sights
Yes.
Consider that if the centerline (C/L) of the barrel and the centerline of the rail are not concentric., even by just a few .001"s of an inch at the barrel nut, it means that the end of the rail is out even more at the end that the front sight is mounted to. Another variable is the C/L of the receiver being out to the C/L of the barrel.
In my situation, the front sight is neither in line with the barrel’s centerline, nor the rail’s centerline. The front sight is literally pushed off to one side of the rail because the sight itself is not symmetric. The large flip-up part of the sight is not anywhere close to centered with itself, the rail, nor the barrel.
I’m not concerned with having to adjust windage. That is normal. I am concerned that the front sight is so far out of what a reasonable person would consider to be “centered,” even if by eye. This leads me to believe there is something wrong with Troy’s manufacturing… or it’s intentional for some reason.
I am out of town for Thanksgiving. But when I get back I will post a photo so y’all can see what I’m talking about.
