Rear sight for Crosman steel breech

7624452 · November 16, 2012, 09:48:42 PM

I have not been able to find a suitable rear sight for a steel breech. The gigantic micrometer sights are not acceptable to me. If the Crosman breech had a normal dovetail slot there would be no problem. Does anyone know the reason for the over sized slot ? Also, could any of you expert metal carvers make a sight that would fit ? I'm sure there would be a huge market for it.

I made my own adjustable rear sight for the stock breech, it works well. I have some ideas for a dovetail mount rear I may try carving out. I've seen some people use a BSA sight, but not sure which one.

I am sure Crosman uses a proprietary dovetail on the rear of the breech so you have to buy a sight solution from them. Some people have had good luck using the inexpensive Industry Brand rear sight from Archer Airguns - http://www.archerairguns.com/Rear-Field-Sight-p/aarfsight.htm

What's a "normal" dovetail slot dimension? Seems to me that S&W are Diff than Colt which are diff than Sig, which are diff than Crosman etc.

Here's the Midway listing of the LPA sights (same maker as Crosmans) http://www.midwayusa.com/find?dimensionids=4294845840&newcategorydimensionid=1675

That's a good point. I would call the dovetail slot on a .22 PB to be normal to my perspective.

It's OK to have a proprietary sight, the problem is that they do not have any for sale.

I found it cheaper to buy a steel breech (GMAC) that supported the standard rear sight.

If you click on it, it says "This Item is NOT FOR SALE", and has been saying that for some time now.

Pyramyd is taking pre-orders and is currently stating a ship date of 11-23-12. That date keeps moving, though.

Thanks for posting this link chef...This looks like a good option...

I have two of them and they will not adjust low enough. I will probably use them when I figure out a way to raise the front blade on a Chavka band.

Mark5043 · November 18, 2012, 03:46:35 AM

Oh,I see.I'm trying to visualize how one could raise the front blade on the Chavka band?
Hard to tell from the Pic of the Industry Brand Rear Field Sight,without seeing one in person,but I'm wondering if there's
enough material on that rear sight blade to remove some,and then notch it again,thereby leveling things out enough? I don't know..Just a thought...

normal to me is a Colt 1911 sight. I called Crosman and the nice lady I talked to said that they did not know when the LPA MIM sight would be in. She did not know why anyone there would let me pre-order one.
