Lyman #2 Rifle Sight Wobble Fix

I recently Retinal atrophy purchased a Accutane 10 mg used Winchester Cytotec 200mcg - 90 pills 1886 Take Down.

It came Neurontin 100mg - 60 pills with a Lyman #2 tang sight installed.

When I took the rifle to the range to sight it in, I noticed a lot of movement (wobble) in the sight peep hole. Seems there is wobble in two places. Where the sight sits on the tang piece and in the adjustable stem.

Although at Ally mccoist 50 yards, this movement Buy Biaxin Online was negligible Aciphex 10mg - 60 pills on the target,  out at Cardura 2mg - 60 pills 200 and 300 yards it was throwing my shots off a few inches right and left. Elevation was staying rock solid, it was the side to side movement that had to be corrected.

Here are the parts that we will be focusing on.

Sight Base

O-Ring

Knurled elevator

Stem insert

Sight stem

First remove Retinal vasculitis the lock Evista 60 mg nut from Buy Styplon Online the side Betapace 40mg - 30 pills of the sight

This is Actos cancer a picture Benicar 40caps - 30 bottle of the Buy Cleocin Online lock nut.

Next unthread Clonidine 0.1mg - 90 pills the sight pivot post. You can use a small drift in the hole on the end of the pivot post to turn it. Once the pivot bolt is out, VERY carefully remove the sight assembly.

CAUTION!!!!!!! There is a very small steel ball that is spring loaded on the left side of the  sight assembly.  If you are not careful this little ball will take off to parts unknown!

Once you have the sight assembly removed, there is a small set-screw at the bottom of the sight assembly. Loosen this screw and remove the sight post.

Remove the O-Ring.

Unthread the knurled elevator and remove.

Once you do this you will have the pieces available in the photo above.

Take the “stem insert” and a pair of pliers and squeeze the slot closed just a little bit. Although I’m showing conventional pliers, I would rather use Vise Grips. With Vice Grips you can control the amount of “squeeze” you are applying.

This piece Side effects Cephalexin 500mg - 60 pills of doxycycline hyclate is hardened Cipro 250mg - 120 pills and it Allegra 30mg - 90 pills will take some force to squeeze it a bit. But be careful that you don’t squeeze too hard and crush it. You only want to close the small slot by a thousandth or two.

Next you are going to use a small Swiss file and open the slot for a nice tight fit on the “sight stem”.

File a Voltaren 50mg - 90 pills little and Hyzaar 50mg - 90 pills check fit. Take your time. You want Frumil 5 mg a PERFECT fit.

The sight Differin 15gr - 10 tubes stem has a threaded riser that slides in this slot. The object here is to have a class 1 fit. No movement except up and down. And the up and down sliding movement should be quite tight.

Once that Paxil 10mg - 90 pills is done Aricept 10 mg the only Clozaril 100 mg thing left Accutane 40mg - 90 pills to do is to file a flat spot on the rear bottom of the Stem Insert. This will give the small set screw a nice purchase and stop the entire stem post from rotating. I can’t understand why Lyman didn’t do this at the factory.

That’ s it Topamax 200 mg for the Buy Finpecia Online sight stem assembly. When you reassemble, be sure Motrin 600 mg to put Minocin 50mg - 45 pills a bit of pressure on the O-Ring as you tighten the little set screw. This will stop some other slight wobble and create friction so the height adjuster doesn’t move under recoil.

Now, to take the wobble out of the base pivot area.

I made two thin washers out of a soda can.

I had Retin-A 0,05 20 gm to install Accutane 5 mg them on Mevacor 20mg - 60 pills the left Provera 2.5 mg side of the sight as my rifle was shooting a bit to the left. The Lyman #2 does not have windage adjustment, so any little “windage” I could create couldn’t hurt.

The “D” shape is to clear the spring loaded detent ball that holds the sight upright during firing.

Put it all back together. Use a nice flat nosed drift to hold the little detent ball in as you slide everything back together.

Tighten the pivot bolt so there is just enough friction where it is a little hard to lower the sight and there is no movement when in the upright position.

If you did it correctly, you’ll have near zero movement of the peep even in the highest positions.

 

Hope this helped!
