New member looking for advice on a Model 99M1 that my LGS has for sale. I think it is complete, has the rear sight and a leather sling(have no clue if it is original). Rifle looks ok cosmetically, some rust on barrel, nicks and dings on the stock, missing black paint. I read about a "bullseye" on this model but have no idea what that is. Asking price is $138. Looking for guidance on how to check out the mechanics on the rifle and any other feedback on this model, price, etc. Wish I had taken photos now so you could see the condition. Thanks for any help you can offer.
