S&J Remington 870 bayonet and mag extension kit, help.

[Mikeinhistory]

Hello. I was looking for some help or maybe advice from others. I recently purchased this bayonet kit from S&J hardware for my remington 870. It have several issues with it and was hoping someone might have had experience with it and could maybe explain what I am supposed to do.

First, the lug for the bayonet does not fit. I have a bayonet for my AR 15 that fits and wanted to be able to use it on both. I think I can grind down part of the lug and it will work. The tabs on the back of the bayonet handle seem to need only the tiniest bit more space. My big problem is it came with no instructions. I figured out how to get the mag extension on the shotgun and the bayonet lug on with no problem, but I cannot figure out how to attach the sling loop. It came with a metal ring that I assume clamps it into place. I cannot get it over the tab that holds it into place.

If anyone has had experience with this or can figure it out and give me some advice I'd be very grateful.

Don't grind anything yet.....

I have one on my 870. You should be able adjust the lug forward enough on the barrel and extension for the bayonet to fit. You have a very long extension You can also get a shorter mag extension. As far as the rings, they can be a bitch to get on, and it can test your patience..but can be done..

Oh, I know that I can move it forward toward the muzzle. That wasn't what I mean. I meant the actually tab that slides into the rear handle of the bayonet itself seems to have the two side cuts just a little off. The too tabs on the bayonet won't close on it so it can just be pulled off.

What method did you use to get the ring on? I have just been using the hammer and punch method.

My lug fits the bayonet perfectly..What brand bayonet (curious)? Mine is a Conetta (1968 was the only year they made them iirc).

I am guessing that the sling mount goes on the mag tube extension right up by the knurled end. Then the spring clip goes into the groove in front of it. Either circular cut goes toward the barrel and can be flipped for a left, right, or straight down sling mount.

Just guessing though. I haven't messed with one.

That is my understanding too. I am not using it on my 870. There are pliers for those clips, but I've never had any luck with them. Once you get is started you should be able to slide it down the tube into place. I would put the sling swivel in place before attaching the extension to the magazine tube.

I had to file some metal off the lug to get the bayo to snap on mine.
It was not a lot.
I have no experience with the sling ring. Does it fit behind the screw on mag cap?

run down to the auto parts store and buy a pair of snap ring expanders. Sorta look like a pair of pliers. Use them to open up the ring.

Yes, I think that is all I have to do. It looks so close. The sling ring will not fit behind the screw cap and also the screw cap will not come off allowing me to put it on the easy way. I think I will have to get some snap ring expanders as well. Thanks everyone.

In the end all it took was some slip ring pliers. Although, it didn't help that I put the sling loop on first and then realized I couldn't screw it back on and had to take it all off and do it again. But it worked out. The bayonet lug still needs some filing but I think it will all work out.

Glad you got it figured out. Looks good.

Looks neat-0!

 

[Mikeinhistory]

Thanks guys.

Nicely done.....

Here's a few pics of mine.
I had to file a tad off each side of the outside edge of the lug to fit the lock on the M-9.

Looks good Moonpie. Interesting how mine sticks out much further than yours does.

Your tube extension looks like a +3.

Mine is a +2.
