What locking block do I need? Help please

[john fisher]

So I just bought a Remington 870 wingmaster in 12 gauge and the dealer said that it needed just a couple of parts. I decided to pick it up for 140 dollars since it was in very good condition. When I disassembled it, I noticed it was missing the firing pin spring and the locking block. It's a 1974 wingmaster that shoots 12 gauge. I've looked online and I've seen oversized locking blocks, or old style locking blocks, and is it okay if I put a 20 gauge locking block in it? BTW it's not a magnum and it only accepts 2.75 inch shells.

Remington has always been pretty good on the phone, and that's recent enough that they should have good records. Call them Monday.

Just for my own information, how the heck do you lose the locking block? My son's and I have seven well used 870s, one with over a quarter million rounds through it, and all have theirs. There is virtually no reason to remove one. I understand that you didn't do it but this puzzles me. I've replaced a half dozen firing pins and extractors but never had a need to mess with the block. Call me stumped.

Yeah I get you, I was wondering myself who would spend the time to take those parts out when it's not exactly the simplest thing to take the pin out.

The side pins on the locking block have been known to break off. And people have damaged them replacing a firing pin spring.

Do all locking blocks have side pins? I've noticed that in ebay that some don't have the side pins and I have wondered if it's because it's some older style or something.

The locking block is held in by the firing pin. Probably lost everything when the pin broke. While you are looking for parts, the firing pin retainer is also missing.

Unless you have a supermag, you should be able to put just about any 870 12 ga bolt/block in.
