IF your shotgun is the Smith & Wesson Eastfield 916, it has been out of production for some time. SOME (not all) parts are available from Numrich- see their website at gunpartscorp. You can also check with local gunsmiths, gun shows, etc.
Best left to a trained gunsmith.
75-150 US Dollars
If you have taken it down farther than you can remember how to reassemble it, it's time to take it to a gunsmith. If you are determined to do it your self, there are several books on shotgun disassembly/reassembly. Check out DBI publishing or Amazon.com to find one which has your shotgun.
