Description
The KNS Precision Parkerized Front Swivel Stud solves a common problem for anyone running an A-2 style or free float handguard: no clean place to hang a sling up front. This all-steel stud mounts through your handguard and gives you a proper quick-release sling attachment point without turning your rifle into a project. It pairs perfectly with 1-1/4 inch QD sling swivels and keeps everything looking the part on a classic AR-15 or M16 build.
What Makes the Front Swivel Stud Tick
The stud is machined from steel and wears a parkerized dark gray finish that blends right in with military-style hardware and A-2 furniture. The mounting hole on the stud is cross-drilled, which means you can route your sling swivel either side-to-side or front-to-back depending on how you carry. That little bit of flexibility makes a real difference when you're dialing in a sling setup for patrol-style carry versus a more traditional two-point hang.
Fitting the Parkerized Front Swivel Stud to Your Rifle
Installation is straightforward and doesn't call for any exotic tools. On standard A-2 style handguards, the stud attaches through a top or bottom vent hole after you pull the handguard and heat shield, so there's no permanent modification to the rifle. Free float tubes require a single 5/16 inch drilled hole to accept the stud. A key detail worth remembering: the pin needs to rotate freely once the retaining nut is snugged down, and a drop of thread locker keeps everything from backing out under recoil.
Why Shooters Reach for This Stud
KNS Precision builds its parts in Fredericksburg, Texas, and this front stud earns steady praise for being simple, solid, and a clean match to existing parkerized hardware. The quick-release design also means you can pop the sling off in seconds when you're cleaning the rifle or separating the upper and lower receivers. For a military-correct AR build or an M16 clone, it's one of those small upgrades that just makes sense.

Frequently Asked Questions
Does the Parkerized Front Swivel Stud require drilling to install?
It depends on your handguard. On standard A-2 style handguards it mounts through an existing top or bottom vent hole with no modification needed. Free float tubes require a single 5/16 inch drilled hole to accept the stud.
What size sling swivel does the front stud accept?
The stud is designed to work with 1-1/4 inch quick-release sling swivels, which are sold separately. The mounting hole is cross-drilled so you can run the swivel side-to-side or front-to-back.
Will this front swivel stud fit my AR-15?
Yes, it's made for AR-15 and M16 platforms and works with both free float and A-2 style detachable handguards. Just make sure your handguard has a vent hole to mount through, or that you're comfortable drilling a single hole on a free float tube.
Does the sling come off easily for cleaning?
That's one of the main selling points. The quick-release design lets you pop the sling off in seconds when you're cleaning the rifle or separating the upper and lower receivers, then clip it back on just as fast.
