TC Hawken rear sight e-clip size

on one of my tc the rear sight was froze up from corrosion, I recently aquirred this rifle so I went through the W-D 40 to loosen it up I thought I would take it completely apart clean it up and re install. the first time not a problem the second time I got everything nice and clean went to install the e clip on the rear sight that adjusts windage and it took off. ive literally tore my work room apart trying to find it. if I know the size I can ordere one, hope I don't have to order a rear sight just for an e-clip ive got an extra set of sights for a greyhawk/ New Englander but those sights don't have an e-clip

Best way to find the lil booger is to order a new one for $.89 cents and $14.99 shipping. Soon as the cards is charged you will find it. Likely with 4-5 feet of where you were working in a place too obvious to have ever thought to look (like stuck, by a bit of grease, to a box with a perfect blend in). :shake:

Why not just take the sight to a hardware store? E rings are very common parts.

X2 on Mr. Troll. An Ace or True Value hardware should be able to help you along with any good locally owned one. An automotive parts store might be able to match it too.

I have a supply of small e clips. If you could measure the shaft diameter at the groove, I may have some that would fit.

Go down to the dollar store and buy a magnet.
Put it on a string and comb the area where you were working.
mine is missing as well, and I wound a fine wire around the the area where the clip was.

You have to use the right method to find lost parts.
I once dropped an under-rib screw onto my patio; right at my feet; of course, I could not see/find it.
So I went an got my big stick handled magnet. I grid searched the patio (and beyond) with the magnet for about an hour covering every square inch multiple times; no luck. (Don't short cut the magnet search; it is a necessary step; go slow and cover the area many, many times; note, however that you will not find the missing part with the magnet.)
I then mumbled something appropriate and went and got myself a cold one. I cracked open the cold one, took a deep breath and let it out slowly saying to myself, "I give up."
Then I looked down to where I had seen the screw hit the patio; of course it was right there.
Now check it with the magnet; yep, it's magnetic.
One more deep breath and repeat after me, "It just doesn't matter."

Check with The Gun Works.

Check with the closest W.W. Grainger or Auto Zone.

My local NAPA auto parts always has what I need for E-clips and the small #4 screws used on some firearms.

Or you could use this situation as an opportunity to " keep tradition alive". Cut a dovetail and slide a plain sight in there. Hacksaw and files, one a triangular.
