Description
The GrovTec GTSW297 is a simple, well-made fix for one of the most common complaints out there: a Remington 870 that gets heavy after a long day of carrying it by hand. This set swaps your factory magazine cap for a machined steel replacement with a built-in push button base, so you can clip on a QD sling and carry your shotgun the way it should be carried. It's the kind of upgrade that costs a little and pays off every time you're walking a field or sitting in a blind.
What the GrovTec 870 Mag Cap Set Brings to the Table
Everything here is built from steel and finished in black oxide, which does a solid job keeping rust and corrosion at bay through wet mornings and rough handling. Close-tolerance machining means the cap threads onto the mag tube snug and quiet, without the rattle you sometimes get from cheaper sling hardware. The set includes the replacement cap and a standard 1-inch loop push button swivel, so you've got everything you need to mount a sling right out of the package.
Fit and Swivel Compatibility
This cap is made for the Remington 870 in 12 gauge and also works on the Model 1100 in the same gauge, using a detent for proper installation. Beyond the included swivel, the cap accepts any GrovTec push button swivel, twist lock swivel, or the GrovTec multi-adaptor stud, which gives you room to run whatever sling setup fits your hunting or range routine. Made in the USA, it's a straightforward part that does exactly what it promises.
Installation is about as easy as it gets. Unthread your factory cap, thread on the GrovTec cap, snap in the swivel, and attach your sling. No gunsmithing, no permanent changes, and you can go back to the original cap any time you want.

Frequently Asked Questions
Will this GrovTec mag cap fit my Remington 870?
Yes, the GTSW297 is designed specifically for the Remington 870 in 12 gauge, and it also fits the Model 1100 in 12 gauge. It threads on in place of your factory cap using a detent for proper installation. If you have a different gauge or model, GrovTec makes separate caps sized for those guns.
Does the Remington 870 mag cap come with a swivel, or do I need to buy one separately?
The set comes complete with a standard 1-inch loop push button swivel, so you can mount a sling right away. The cap also accepts any GrovTec push button swivel, twist lock swivel, or the multi-adaptor stud if you want to swap in a different setup down the road.
Is installation difficult?
Not at all. You simply unthread your factory magazine cap, thread on the GrovTec cap, and snap in the swivel. There's no gunsmithing or permanent modification required, and you can reinstall your original cap whenever you like.
Will the black oxide finish hold up in wet hunting conditions?
The all-steel build with black oxide finish is made to resist rust and corrosion through wet mornings and hard use. It's a durable part meant for years of real field carry. As with any steel component, a quick wipe-down after a soaking wet outing helps it last even longer.
