870 ButtStock Sling Swivel Location/ Measurement

[Mank10]

Thanks for the add/forum!

I am building a 870 Riot Clone and looking for the correct 513t Buttstock 1 1/2” sling swivel.

How far from end of buttplate is the screw installed?

Measurements? There is a dimple in bottom of stock at 3 1/4”. Is this the correct location?

Thanks!

Looked up a 513t stock. All I saw were rifle stocks, for a .22 IIRC.

Got pics?

Yes, the dimple at 3 1/4 inches from the bottom edge of the buttplate is exactly where the original sling swivel screw would have gone. Remington often pre-marked this location with a small indentation on factory stocks made for tactical/LE contracts.

For the 870 with a 513T buttstock, the sling swivel is typically installed near the dimple you mentioned. 3 1/4” from the end of the buttplate sounds correct for most standard setups. Make sure the screw lines up with the stock’s reinforced area so it sits securely.

If you want extra precision, you can lightly mark the location with a pencil and test-fit the swivel before final installation to ensure proper alignment and function.

On the originals, that little dimple you’re seeing about 3 1/4" from the bottom edge of the buttplate is exactly where the rear sling swivel screw was meant to go. Remington often pre-marked the stock there for the factory-installed swivel, so you’re in the right spot.

If you want to be extra safe, you can measure from the toe and compare side-to-side to be sure it’s centered before you drill, but that dimple is what you’re looking for.
