Anybody know the size of the metric CirClip TX305(2each) used on the Pivot Pin TX300. Have no idea how one of them got lost when it was never removed. Haven't found a US standard circlip that will work. Its lucky I even noticed the circle was missing. Lucky I didn't loose the pin.

TX200 need help on part size

Sorry but someone certainly will. Personally needing that airgun right now and all I would I would be at the hardware or auto parts shop rifle pin in hand.
Off topic but it seems JM has a few TX200 forarm brackets on the sale page: https://www.airrifleheadquarters.com/catalog.html

They are a metric "e" clip or circlip as some call them. Cant remember whether they are 3 or 4 mm clip. If all else fails I may still have some left, but I will have to search for them. They are quite cheap, usually a small pkg for a buck or two.

Chambers airgun spares lists them (listed as part # CL006). I have had good results using them for parts when I need parts. There is a thread on Gateway about this same thing, he said a 5/32" fit, but there are metic e-clip kits on EBay for ~$7.50 that have 3mm clips.

I know good hardware stores are quite rare these days, but I do have a good one about 15 miles away. Also these can be ordered thru a fastener company or someone like McMaster Carr.

I measure 5mm for the shaft and 7.3mm for the e-clip installed. Which matches up with item DE-032 from this supplier. There should be enough dimensional information there to select the right part from other suppliers as well.

Michigander - the Pro Elite uses the same e-clip as the TX200 as far as I can tell. It has the same part number, and the Airgun Spares site lists the TX200 part to also fit the Pro Elite. I ordered the last one they had in stock a couple of days ago.
My Pro Elite is apart right now so it's easy for me to measure the groove in which the clip fits. I get 4.06mm (measured) for the groove diameter, and 0.75mm for the groove width. The cocking link pin itself is 0.196" outside diameter (4.98mm) measured, which is likely a 5mm nominal diameter like yours.
From the PDF chart that you linked to, I'd look for a clip for a 4mm groove diameter and choose part DE-040 instead of the DE-032 clip.
I checked Mcmaster's metric e-clip offerings, and their part number 98543A112 is a little thicker and a bit larger O.D. than the Pro Elite/TX200 clip that I measured. The original Pro Elite e-clip that I have measures 7.19mm OD, 0.56mm thick, and of course fits my 4mm diameter groove.
I am going to place an order for supplies from McMaster in the near future, and I thought that I'd try their clips anyway. The measurements indicate a fit, and the extra OD of their clips will still fit in the flat on the breech. The best part is that 100 of them cost only $3.45 (plus shipping), so I thought that it would be a good experiment.

If you coat the area in clear grease, these don't fly off into neverland. Ask me how i learned this

Well, I just took receipt of 100 McMaster-Carr 4mm e-clips, and they don't work. They are a loose, slip fit over the groove. I placed another order a few minutes ago for the 3.2mm version. Michigander was correct, and I was wrong. I'll chalk the cost up to a learning experience.
If the OP is still following this thread, I'll test the new clips on Wednesday or Thursday and report back. If it works, I'll tape a few of them to a letter, stick it in an envelope, and mail it to the OP at no cost.

Bill_S, If the ones you ordered the second time don't fit, let me know. I found some listed as 3mm and it fit. Measured with calipers, it is same size as the one on the other end of pin that I did not loose.
Thanks everyone for your input.

Jonah - I'll keep you posted about the new clips that I have coming.
Delivery is expected today, but here in the small towns, predicted delivery times are essentially rough estimates.

The new clips are in and they fit.
They require more force to insert than my original clips, but the old ones have been worn a bit. Here's a shot of one of them on my Pro Elite, and how they nestle into the recess for them ...
Of course you can't attach them on a close-fitting round recess, so this is a shot of the other side - without the pin or clip.
Johan - if you want a few more to have as spares at no cost, just send me a PM. I have a lot left over!

Bill-S, I was going to tell you I’d send some to you if yours didn’t work. Thanks for the offer, I also found some. Nice that people are willing to share.
