View Full Version : Remington 870 Disassembly Questions
January 15, 2008, 12:40 AM
I just got a Remington 870 Home Defense (synthetic stock and 2 shot mag extension) and the manual doesn't really address several issues. At what point do you need to remove the barrel clamp/band, or do you even have to remove it to disassemble the gun? When I unscrew the mag cap, does it slide over the end of the mag extension or does the entire assembly come off? I have watched several videos, and searched several forums, but I haven't found the specific answers to my questions yet. Also, does anyone know of a way to change the front handguard without a special tool? Thanks in advance if anyone can provide any info, pictures, videos, links, etc.

Yes, you have to remove the barrel/mag clamp first. Take the screw out of it and it slides off the end of the barrel/magazine. Then unscrew the mag extension. It should come off in one piece, but the nut on the end of it may come off separately. Both of mine stay together when they come off, but I've heard others have them come apart. If it's too tight to hand turn (sometimes they are from the factory) use a pair of well padded pliers. When you reinstall it, hand tight is enough. Once that is done you should be able to get the barrel off and then proceed with disassembly (if you need to).
For removing the forend I made my own tool. I took a piece of steel rod and bent it into a horseshoe shape that is sized perfectly for engaging those grooves. I take a big pair of channelock pliers to turn it. Works like a charm.

I watched the videos on youtube, but that gun doesn't have an extended mag or barrel clamp. That was the part that was in question.

I have the same 870. What are you trying to do?
Just take off the barrel /clamp band whenever.
You dont' even need it.
My 870 ChP Wingmaster has an 18" barrel and a 3 shot ext with no clamp, just fine.
So if you are doing a dissassembly, just take it off first , and put it back on at the end.
Yes, the extention needed to be removed with a rag and a set of channel locks. Hand tighten back on.
