The Harris #6A Adapter is the little piece that bridges your Harris bipod and an American-style rail. If your rifle already wears a rail with slots measuring 5/16" across, this stud drops in, locks down, and gives your bipod the standard sling-swivel stud it's built to clamp onto. It's a small part that solves a common headache, letting you run a proven Harris bipod on a setup that didn't come with a swivel stud from the factory.
Installation is about as straightforward as it gets. The adapter slides into a 5/16" American rail slot and locks into place with a set screw, so once it's snugged down it isn't going anywhere. That set-screw design keeps things low-profile and stable, which matters when you're leaning into the bipod for a steady shot. One thing worth noting before you order: this stud is made specifically for American-size T-slot rails, not Picatinny or European rails, so it pays to measure your slot at 5/16" to be sure you've got the right fit.
Harris has earned its reputation as the standard for bipods, and their adapters carry the same no-nonsense quality. The #6A is machined from black metal and made in the USA, so it holds up to real recoil and real weather without wallowing out or rusting on you. There's nothing flashy here, just a durable stud that does exactly one job and does it well.
Whether you're setting up on the bench, dialing in loads at the range, or dropping prone in the field, the #6A gets your Harris bipod locked onto an American rail with zero fuss. It's an inexpensive way to keep a bipod you already trust in the game on a different rifle or rail setup.
The #6A is made for American-size rails that measure 5/16" across the rail slot. It slides into that T-slot and locks in with a set screw. It is not designed for Picatinny or European-style rails, so measure your slot before ordering to make sure you have the right fit.
Yes. The #6A gives you the standard swivel-stud interface that Harris bipods are built to clamp onto. Once the adapter is locked into your American rail, your Harris bipod attaches the same way it would to a factory sling-swivel stud.
Not directly. The #6A is designed for American T-slot rails, not round AR handguards or Picatinny sections. For a round AR-15 or M16 handguard, Harris offers different adapters like the #5, so it is worth confirming your setup before choosing.
It locks in place with a set screw after sliding into the rail slot. That keeps it snug and low-profile so it won't shift under recoil. Just make sure your firearm is unloaded before you start the install.
