I have a remington 870 that I want to use a convertible 1pt to 2pt sling on, the same as I do with my AR. The current problem is the sling does not work right because the forward attachment point on the barrel clamp is too far forward. Obviously I cannot attach it to the slide or it could move the action. I have a hook on the back of the receiver where the side saddle pins for the first attachment point and I was trying to think of how I could add a second attachment point on the from of the receiver so the sling would function properly. I have looked at other slings but haven't found any made for the 870 that will function the same way. I really like the way the sling works too.

Is there anywhere on the front of the receiver with enough meat that I could thread and attach a sling point to?

No ideas?

Not sure if I can help . Ever thought of drill and tap upper receiver for a pic rail and adding a sling loop that hooks onto pic rails (like a rsa or gmg) ? Dunno what sights your running. To add extra strength... Sand upper receiver where pic rail meets receiver, clean thoroughly, and nicely bed it with high strength epoxy,. Use small amount of epoxy and Loctite screws in. At least if u sell it, people may be looking for an 870 with top pic rail. And I think there's a pic rail with ghost ring sights. That may interest you and the magpul rsa mount attaches the sling to the side (kind of like a 45 degree offset sights for ar15) please be aware I'm uncertain if it will block you sights from working. Never had it before so I really don't know.

So the rear pin that holds receiver together has a sling attachment there? Lol.. I use to have a remy 870 express tactical but I ran single sling with loop plate where buttstock met receiver. I had no problem with my magpul sling reaching from that plate to front of tube and I had +6 or 7 tube. I don't remember lol but it was the one piece tube from Remington itself. It had 18.5 inch barrel.

I'd like to see that sling loop thing on the receiver.

what sling is this? Model?

Edit to my earlier post... Which model 870 do you have?

And you wanted to carry the traditional 2 pt sling way. Like normal bolt action rifle way...?
How long is your mag tube? Or how many rounds can it carry?

It is an express magnum I think, 18" barrels with the tube extension.

Someone else did suggest the rail on top but I have to check my wilson combat ghost ring sights and see if it would interfere.

The sling attachment I have came from a shotgun accessory company I always forget their name. It has a pivot and it attaches on the first hole where the side saddle screws in. Oh, here is the product.

Nordic mag tube clamp with a qd socket would solve the front problem and drill a spot for the qd on the stock.

Yup Henry is right, if there is room between the forearm and screw on cap for mag tube, install a clamp with ad socket or pic rail. It'll only work if you have the one piece mag tube though as I did I believe. If you have a +4 or +3 mag tube or whatever that short one with the screw on mag tube to extend the capacity it won't work.

Above statement I think will work.

Didn't know Mesa had that. Guess it's been a while since I've looked up shotgun stuff. I do plan on either making one more rifle or buy 2 mossys though 😓

How long can your sling fully extend?

So in this pic, where you see he attached the front of the sling there's clamps you may use ... like this (if u wanna use Harris style mounts Blackhawks sells it I think.)

There's ones with qd sockets too.. Just attach it between screw on mag extension (closer to forearm) and it'll save you some inches

Here's more options...

Stole these pics of Internet.. Lol.. No need to cut into receiver .. All these clamps can save you few inches in length.

Btw does that Mesa thing only work on rear receiver pin? If you could move it to front it could save you a couple more inches, but idk how well balanced it would be after the fact

The issue is that the 1 pt to 2 pt conversion sling I have will not work off my forward tube clamp, it is just designed too short, for an AR length operation. I was hoping to make it fit so that I get uniformity of use across platforms rather than learn and practice with a different system. I think drilling and tapping the top or the receiver for a rail might be my best option.

Yeah I'd go with that then.. Sorry I wasn't much help. Maybe if I could see it in person I would've understood better. I thought it was like a magpul sling where 2 ends (can extend to bout 2-3 feet or so or whatever length it is) and then if you wanted a 1 point sling, simply take off front and attach it to rear point (kinda looks like a d ring) .

Here is the sling I am using. I played with it to see if I could lengthen it but that won't work.

This product might accomplish what I want without having to drill and tap!
 Hopefully it doesn't compromise it to have a sling point attached...

Yo, keep in mind having a rail mounted sling adapter may intefere of holding a shell. Also when I bought my first gen shell carrier side saddle I'm pretty sure they gave me new receiver pins and I think it screwed in to each other. So you may lose that sling thing on your receiver pin you have now. Also the sling will rest against the ammo that would be in the side saddle, but that's just an observation in my head. I never tried it though.

another option but idk if you'll like this. Buy a rear sling adapter like for an a2 rifle buttstock. You can hook a sling to it and it won't intefere with side saddle( that's if you ultimately want a side saddle) should not move cause it's strapped vertically and horizontally.

It'll ride different than the guy in the video I watched from the first link. But at least it'll be cheap. Definitely won't know if you will like it that way and not sure of what stock you have on your remy.

Here's another option to the one above statement.

This will take time and if you like tinkering it should work. And if you don't care bout a stock buttstock (assuming you have one)

Take rear buttpad off. Sand half an inch from rear and desired point of where you would like to mount a sling. Sand bout 2-3 inches on inside just use a low grit and swipe over a few time to add texture only, try not to take off too much material. Use high strength epoxy and some sheetmetal  cut to a good size maybe a lil bit longer and wider than the pic rail mounting points, and glue it to inside of buttstock. Buy a sector gear rail or any other rail but try get a sector gear sling adapter. Drill your buttstock and epoxy and sheet metal to mount the pic rail on. Might have to go Home Depot to get longer screws, or bolts to mount good. I'd prefer bolts and nuts and some Loctite. And voila a cool and fun way to add a pic rail to your buttstock.

I'm not sure if the base of buttpad won't allow you enough space to do it so check first, measure everything twice over so you won't screw up. I always do. It's good practice. I've done a lot of fabrications for vehicles before so I found it fun.

The sheetmetal will disperse weight therefore adding rigidity. There's epoxy out there with 9k psi so I don't think a 10 lb gun should break it. Hell I did add a pic rail to my tikka stock and its help up with epoxy and fiberglass.  But I think I was using 12-19k psi epoxy.

Hope that helps too if you wanna have a very unique thing lol. If you have a stock buttstock fro. Remington I assume it has a 13" lop so that's pretty much how far the sling point will be from one another. I'm not sure if that's too short . I the vid it looks about  13-15 inches in between the 2 sling points.

Night

Can you take a pic of your gun or find a pic of the exact model with exact features.

I should post a pic of what I have.

The sling swivel now mounts over these saddle so the length works alright.
The A2 sling you mention might not work right because I have a choate youth stock and it has a different angle on the underside.

The new mesa side saddle looks be the simplest option.
