ok , if you want a controlled round feed , or push feed , try going to www.winchester-guns.com ,

or you could try remington at www.remington.com

or ruger for controlled round feed actions at www.ruger-firearms.com


hope that helps , some of those sites even give the phone numbers and fax numbers for them but , some you' ll need to have acrobat adobe reader to download thier parts catalog , once again , hope that helped , later buddy
