Crossman Power Master 760-1 When I took apart the rifle a small metal disk fell out and I don't know where it goes. The rifle has the brass bolt.

Question edited for clarity.
Question moved form Cars and Trucks Category.

Click the link, then click on the images tab for parts schematics. It sounds like the 'sight group'.

The manufacturer should be able to help you out. Their phone number is (800) 243-9700.

Rifle presumably was in a hard case so unlikely suffered any damage from such a short drop. A 3 foot drop is a short drop for a half-decent rifle with no case. I am guessing the problem is likely damage to the sight and it will probably need an experienced eye...

I think you are asking for an EXPLANATION of why, when you put a bullet in a CHAMBER with your fingers the bolt won't close but when you put the bullet in the magazine, it goes in the chamber and the bolt locks DOWN fine. Is THAT a safety system?

ANSWER: No, it is not a safety system. I am assuming that you are speaking of a standard BOLT ACTION rifle in a centerfire caliber configuration. The extractor, located near the bolt face is why it won't close. When you put the bullet into the chamber and then try to shut the bolt, the extractor has to jump over the rim of the shell casing. When you place the bullet in the magazine and then shut the bolt, the bolt face pushes the bullet up out of the magazine allowing the rim of the case to slide between the bolt face and the extractor claw and feed into the chamber. After firing or if you simply just want to remove the bullet from the chamber, pulling the bolt rearward, the extractor claw hangs onto the rim until the case hits an extractor bar causing the shell to fly out of the rifle.
A good question.
I would suggest a firearms training session. Check with the NRA or a local gun club for help.

Hello, Mike -

1. I took the liberty of re-categorizing your question from Optics (binoculars, gun sights, lenses, etc.) where it landed, to Firearms.

2. I doubt most who volunteer to answer questions on Fixya.com are qualified to provide you a value for your rifle. For one thing, an appraiser would need to look and handle the rifle, which is a major challenge online. :) (Note: My now late father, a licensed auctioneer, used to sell the firearms of his friends who had passed away for their widows and I know he needed to look over all of the firearms in-person.)

3. As for the year your Winchester 1890 was manufactured, you are fortunate in that the Winchester Repeating Arms company provides a PDF document (you will need Adobe Acrobat Reader software (free) installed) listing the models of firearms and range of serial numbers and what year they were manufactured. This is the link:
http://www.winchesterguns.com/content/dam/winchester-repeating-arms/support/faq/serial-number-reference/Winchester-Manufacture-Dates-by-Year-2012-Scanned-Documents.pdf

Easier than looking through the lists on the Winchester Repeating Arms document, though, the database offered by the website for Antique Guns and Collectible Firearms and Militaria Headquaters
(home page: http://oldguns.net/ ), Winchester Dates of Manufacture:
http://oldguns.net/sn_php/winmods.htm
I think you can figure it out. :)

4. First, your local public library may hold a recent book or two listing estimated values of firearms. One title which is updated regularly is The Blue Book of Gun Values. Note: Using your local public library and its collections represents your taxpayer dollars at work!

Second, read the questions and answers about gun appraisers here:

Second, you can conduct a search using your favorite search engine (Google, Bing, Yahoo, DuckDuckGo, etc.) using the following search phrase:
firearms appraiser
OR
firearms appraisals

Third, the International Society of Appraisers provides a database which can be searched. This is the link:
https://www.isa-appraisers.org/find-an-appraiser
Enter the word firearms in the search box.

The American Society of Appraisers offers a similar database:
http://www.appraisers.org/find-an-appraiser
In the ASA Specialty search box (only), choose Firearms.

Personal opinion: To find an appraiser to value your rifle, I suggest you do not go to a firearms dealer, who may opt to purchase your rifle outright, since he / she may have a vested interest in the value of your rifle. Be prepared to pay a fee for an appraisal.

Best wishes.
