A.R.M.S. 40-L SP Question

I just received my A.R.M.S. 40-L SP sight and would like to know if the following is a normal attribute for this device. When open, the sight arm is canted slightly. The sight blades themselves also appear to be canted within the housing. When mounted on the rifle, I do have a clear view through it. So what's the story here, friends? "Out of whack, so send it back." or "Good to go, don't worry so!" Sorry the pics are so blurry, but a photog, I'm not! Thanks and Best!

Don't know. I bought a Troy. Someone will know I'm sure, they will respond soon :wink:
Looks like mine, which shoots dead on.

Mount it, zero it and shoot the hell out of it. If it isn't right, you'll know right quick.
...you're "good to go"... mine are like that also...as long as it flips up smartly into position...you're fine...
Thanks, racenet and ullie! It snaps into position perfectly. It's just that bit of rearward canting seemed odd. Best!
Looking at your second picture you can see the glare in the concaved part of the aperture.

I noticed on mine that with back lighting the glare is distracting.

I took the sight apart and turned the aperture around 180°. After searching for about 1/2 hours for the small ball and spring that fell out I had it back together.

There is no glare and the surface facing the shooter is flat. The sight picture is very good.

Do you think there is any reason for the concaved side to be toward the shooter?

Hey, rainman 74! I appreciate your reply. Please don't take this as mocking you, but I believe that you have the sight mounted backwards on the weapon. From what you described above, it appears to me that you might. I believe the sight should be mounted with the 'concaved' peep facing towards the muzzle of the weapon, and the 'tail', if you will, with the 'flip open' lever facing you. At least that's how I have mine mounted. If I am incorrect here, I'm sure someone will let me know. Perhaps it doesn't really matter which way the sight is mounted, and if this is so, your 'fix' has merit. Best!

If it flips up toward your face, it can toss dirt in your eye....
My sight is mounted correctly. The aperture with the small hole has the concaved surface facing the shooter (as shipped from the mfg.and as shown in your 2nd picture).
The concave part of the apertur with the large hole is at the front (pointed towards the muzzle). They are opposite for whatever reason.

Can't argue with that point! So here's mud in your eye! :wink: Best!

Understood! After checking mine out in bright light, you are correct . . . the glare is pretty potent! However, instead of reversing the blade like you did, I'm going to paint it over with black auto primer (like I do to other sights that 'glare' at me). It dries flat, and reflects nothing! As for your earlier question, sir . . . I can think of no reason as to why the concave side is towards the shooter's eye. Since the peep hole is the same size through (at least it should be!), the sight picture should be the same. Best!
