Description
The safety selector is one of those controls you touch every single time you pick up your rifle, so it pays to run one that feels right. The Watchtower WT SSKBLK Safety Selector Kit is a complete replacement setup for AR-15 style lowers, finished in black and machined for a crisp, positive throw. It ships with both a long and a short paddle so you can tune the feel to your grip and shooting style, along with the tumbler, detent, spring, and two screws that make the swap a one-and-done job.
What Sets the WT SSKBLK Kit Apart
This one uses a standard 90-degree throw, which keeps it familiar and predictable for anyone already trained on a mil-spec AR. The skeletonized shaft trims a little weight and gives the whole assembly a purposeful look that fits right in on a custom build. Because the paddles thread on with screws, you can set up your favorite lever length on the strong side and either match or run a low-profile paddle on the off side to keep it out of the way. It's a small part that makes a real difference in how confidently you can flip from safe to fire.
Getting the Watchtower Safety Selector Installed
Dropping this in is straightforward if you've been inside an AR lower before. Clear the rifle, separate the upper, and pull the grip so you can manage the detent and spring, then seat the selector, set your paddles, and snug the screws with the included hardware. A dab of thread locker on the paddle screws is cheap insurance against them backing out over a long range day. If you're building from a bare lower, it slots right in alongside the rest of your fire control parts.
Watchtower Firearms builds these to the same pattern as their well-regarded selector line, so you're getting matched parts designed to work together rather than a mix of components that may or may not play nice. For a quick, budget-friendly upgrade over a factory selector, it's an easy call for range guns, training rifles, and anything you want feeling a little more dialed.

Frequently Asked Questions
Does the Watchtower WT SSKBLK kit come with everything needed to install it?
Yes, the kit is a complete replacement setup. It includes the selector with a long and short paddle, plus the tumbler, detent, spring, and two screws. You supply the hex wrench and, if you want it, a little thread locker for the paddle screws.
What is the throw on this Watchtower safety selector?
It runs a standard 90-degree throw from safe to fire. That keeps it familiar for anyone trained on a mil-spec AR-15 rather than a short-throw setup. If you specifically want a 45 or 60-degree short throw, this isn't that style.
Can I choose which side the long and short paddles go on?
You can. The kit includes both a long and a short paddle that thread on with screws, so you can set the longer lever on your strong side and run the short paddle on the off side, or configure it however suits your grip. That flexibility helps left-handed and off-hand shooters get a cleaner reach.
Will the WT SSKBLK fit my AR build?
It's designed for standard AR-15 style lower receivers and drops in alongside the rest of your fire control parts. If you've built or worked inside a mil-spec lower before, it'll feel right at home. Just clear the rifle and follow standard safety steps before you start.
