Jaaack, I'm new to the forum set up, so I might not be able to make this happen. I will try to attach a photo of the gun I have. Maybe GeneB might be able to understand the serial number you have to determine if it would work with my gun. Thank you for the offer. I love these guns. I would definitely be interested in yours, if the breech bolt works great. If not, I would like to have another to work on. I put my email in my profile, it is not visible now. I'm not sure of forum etiquette and not sure if I should put it on here. Let me know how the best way to communicate. Thanks again, HalC
