Seekins Precision 8" ARCABlack Anodized Aluminum M-LOK Mount - 3.5 Slot

The Seekins Precision 8" ARCA M-LOK mount brings serious versatility to your rifle setup. This black anodized aluminum rail gives you a dedicated ARCA interface for mounting accessories—bipods, monopods, shooting bags, or other ARCA-compatible gear—while the integrated M-LOK slots let you attach additional tactical equipment to the same rail. If you're running a modern AR platform and want flexibility without adding multiple mounting systems, this is a straightforward way to expand your gun's capability.

Built from aluminum and finished in black anodize for corrosion resistance, the 8-inch length gives you real estate for mounting without unnecessary bulk. The 3.5-slot ARCA section provides a proven interface that works across a wide range of shooting accessories, and the M-LOK mounting pattern is now the standard on most contemporary rifles and handguards. Whether you're setting up a precision rifle for long-range work, a tactical carbine for training, or a hunting gun that benefits from a solid rest, this mount handles the job with the build quality Seekins is known for.

Installation requires removing your handguard or rail and bolting this unit in place of your existing top rail or onto a suitable mounting surface. The combination ARCA/M-LOK design means you're not locked into a single type of accessory—swap between different rigs and configurations as your mission changes.

Frequently Asked Questions

What accessories will mount to the ARCA section?

The ARCA interface accepts any ARCA-compatible accessory, including bipods, monopods, shooting rests, camera mounts, and tactical bags. The 3.5-slot design provides standard ARCA spacing recognized across most major manufacturers.

Will this fit my AR-15?

This mount requires a compatible mounting surface—typically a picatinny rail, M-LOK-equipped handguard, or existing top rail. Verify that your rifle's top rail or handguard can accept this unit before purchase. It is not a drop-in accessory for all AR configurations.

Can I use both the ARCA and M-LOK sections at the same time?

Yes. The mount combines both interfaces on a single rail, so you can attach an ARCA accessory while also using M-LOK slots for additional equipment like lights, lasers, or backup sights.

Is this mount included with my rifle?

No, this is a separate aftermarket accessory. It must be purchased and installed independently on a compatible rifle or handguard.
