Sling mount options 870 SBS

On one of my SBS 870’s 14” Barrel I and wanting to move the forward sling mount to a better location.
On my other three SBS I have the sling mount on the +1 mag extension. This one has a different mag extension and doesn’t have that option.
I currently have the QD mount of the magpul hand guard. I am not fond because it’s uncomfortable holding it with my hand resting beside it after shooting a few boxes of ammo.
My next concern is the added stress on the “action bars”, if that’s the correct term, and don’t like the idea that the sling varies in length/slack when I cycle the pump/hand guard.

There isn’t enough room to install the mag tube/barrel clamp to make that a sling attachment point. I prefer not to buy another +1 mag extension since this isn’t my primary shotgun.

I looked into this with my Remington Tac-14.
I don't quite understand the problem with the 4th SBS vs. the other three SBSs. It'd seem to me you (the poster) would be more expert than anybody as to what will work having four short barreled shotguns.

The Magpul 870 fore-end doesn't seem to readily allow the under-the-mag-extension mount as the fore-end protrudes a bit too much.

Then there's a replacement mag tube cap with a sling swivel, although that would replace the mag extension and result in the mag tube cap being covered by the Magpul fore-end.

I don't know how well cutting the Magpul fore-end will work. Replacing the entire fore-end with a Remington 870P-type might be an alternative.

On my similar Tac-14, I've got a quick-detach mount on the pistol grip adaptor and went with a Magpul sling converted to single-point use. Magpul has various slings with mounts should a single-point method be used with a shotgun.
https://magpul.com/firearm-accessori...gs/slings.html

The single-point option was the best option for me as I like the MLOK slots for a light on my Magpul handguard/fore-end.

Here's a Wilson-Combat one-round mag extension which has a sling stud built in. I didn't try this but looks like a good option if it works with the Magpul fore-end.

Edited to add: also take a look at Wilson-Combat's website for pictures of its shotguns and how they're handling the forward sling mounts.

Screw all my advice, I missed the mag extension on first reading.

I use one of these: https://www.gggaz.com/remington-870-...tachments.html

If you do not have a mag extension, it will still work. I have one of these and have used it with a Wilson +1 extension when running a Vang Comp 14" barrel, and without the mag extension on a custom 12" barrel. It has never been an issue in multiple shotgun classes. I only use a sling for classroom work, around the house it does not wear a sling.

Hope that helps.

He has a Magpul forearm which overlaps the magazine tube/cap junction point.

Ah, gotcha - I did miss that.

It sounds like you have a choice of Dremeling the forearm or buying the new mag tube extension, which you already said you didn't want to do.

I don't know what 870 Tactical the OP has. They make a 7 round edition without a removable extension. The mag tube built into the receiver is longer and the barrel hanger is out toward the muzzle. I he has one with the standard tube the GG&G accessory won't work. It goes over the tube and behind the nut. The MagPul handguard pretty much shrouds the nut. I can put up a picture if needed.

Just in case the OP checks back:

Would you be adverse to drill a hole into the end of your magazine extension and using the short machine screw from this kit to attach the QD socket? (I have 4 shotguns with magtube extensions -three of the four already have a hole drill in the end - so you may not have to drill)

If you are using a rifle type front sight, how about girth hitching a piece of Kevlar boot lace to the barrel to create a loop? Similar to the Proctor sling set up.

If you look at the pictures for this universal sling kit, it has a high temp cord for that purpose.

Yes, the magpul hand guard overlaps the mag extension. The +1 extension is flush with the 14” barrel.
I have the Wilson combat extension on other shotguns and they work great but this one has different extension.

I like the GG&G sling mount but don’t want to cut my hand guard.
Plus if I mount the sling in front of the hand guard it will block the light on the right side (I’m left handed). Hints why I was trying to mount the sling behind the light on the hand guard. Just with the recoil the QD mount was reeking havoc on my thumb and I’m afraid of damaging the action bars.

Jsbhike, do you have a pic of the sling loop attachment?

I guess my only other option is a single point sling.

Is there enough barrel/mag extension for one of these? It would be right out at the muzzle but it might clear the Magpul hand guard.

I don’t think there mag extension/Barrel is long enough for that.

Here is what the SBS started life as.

Hand guard and extension is the same. Just imagine a QD attachment on the hand guard furtherest mlok slot to the rear and a WML on far forward mlok slot.

Something like this may work if I install it in the rear at about 4 o’clock

Man that is stubby. Sling plate behind the mag extension and a different hand guard might be the solution if you don't want to go to a single point sling.

Maybe give Wilson Combat or Vang Comp a call and see if they have done one and maybe have a suggestion.

No idea where the high temp part of the kit went to, but it uses the same ITW loop on a piece of heat resistant cord. https://uploads.tapatalk-cdn.com/202...28fc162490.jpg https://uploads.tapatalk-cdn.com/202...89199dfafb.jpg https://uploads.tapatalk-cdn.com/202...e75ab3a283.jpg https://uploads.tapatalk-cdn.com/202...97741048c8.jpg

Excuse the threaded socket, all I had left for this proof of concept were Grove-Tech screw in sockets for wooden stocks:

It isn't. The Mesa is 2 inches long, the Tac14 extension is 1.50 inches.

I would not want the sling swivel located there, too much flopping around when you cycle.

OP - After some research I believe this will work to clamp on the stubby extension and the barrel:

https://www.brownells.com/shooting-a...prod54745.aspx

I hope so, I ordered one for my TAC-14 (off ebay).

Thanks 26 Inf for the suggestions. I think those will best my best bet.
I ordered the Magpul clamp on and the Grove-Tech QD socket. I’ll try the QD socket first because I think it’ll preform best but will have the clamp style for backup.

I hope I haven't led us down the wrong path.

I went out to get the paper 20 minutes ago and there was a Magpul box sitting by the front door, I was giddy, I thought the clamp had come - forgetting for a moment I ordered it off of ebay - instead I found the boc contained the 21 rounds mags and enhanced buffer tubes I had ordered. Magpul ships fast - I ordered those items late Friday night.

The magpul clamp fit perfect. I installed it tonight.
I pulled the light since the sling is in the way. Light was the same as the other shotgun. Now to find a new light mount that’s up and out of the way.

Here are pics of the one I added the magpul clamp to and another one for reference.

Edit:
Another thought is I could move the light to the bottom of the hand guard.

I like those ghost ring sights on the Tac-14, being shown in Post 20. I've been wondering what to do with my Tac 14's lack of sights. Off topic.

I liked Post-15's idea.
Brownell's QD socket kit was out of stock. After two tries with Amazon, I found this kit (now out of stock as I type this):
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Prior to this, I was using my attached Magpul "MS4" sling in single-point mode, which worked ok, but allows this non-NFA Tac-14 w/brace swing around a bit more than I'd like.

I'll have to work with this forward sling mount to ensure I don't blow the end of the sling off when shooting. I saw this happen in a class a dozen or so years ago (to a San Francisco P.D. Sgt. should he happen to be reading this forum).

I bought some of those generic QD swivels from Brownells. They were 10 or 20 to a pack.

There are plus ones that will do both out there. I replaced the Magpul on my Tac-14 with this Hogue, but this particular plus one works with the Magpul as well.

Update to my Post_22. Today, after having my QD socket (bought from Amazon) for 3 months, the socket fractured lengthwise (front to back direction). I probably had ~300 rounds fired by this time. This particular socket appeared to be cast or MIM and probably couldn't withstand this much repetitive blast.

I've ordered more sockets, this time from Brownell's, as they're in-stock.

Very interesting. Did you have any damage to the mount on the sling or to the sling itself? And powder burn or singed ends on the sling?

No. The sling and sling swivel are fine.

Update:
I did buy another 10 sockets as suggested by Post_23, (Brownell's# https://www.brownells.com/shooting-a...?sku=593000038) and then bought my own hardware.

Flathead screws in either 10-24 or 8-32 size/thread, along with nuts (I preferred the "nylok" type) worked just fine. The nylok type nuts were just easier than using a regular hex nut with Loctite. I think I bought 3/8" long screws. I suppose 1/2" screws would work, too. Be sure to use flathead screws as a different screw-head type won't allow enough room for a QD swivel to fit into the socket otherwise.

Shooting my Tac-14 (now an SBS) again, the socket has stood up to another 200 rounds or so. I probably just had a marginally made socket which was bought from Amazon in a QD kit. Besides this shotgun, I've already used another 3 or 4 sockets located on other guns I had.
