Description
Being able to flick your safety on and off from either side of the receiver is one of those small upgrades that pays off every time you pick up the rifle. The Wilson Combat TRSSAB gives you thumb access from both the left and right, which is a real bonus if you shoot lefty, run a support-hand grip, or just want faster manipulations under a shot timer. It swaps in for a standard mil-spec selector, so you're not reworking your lower to get it running.
What Sets the TRSSAB Selector Apart
This is a double-head, USGI-pattern part that's precisely sintered for a tight, consistent fit, then finished in black nitride to shrug off wear and corrosion. That coating isn't just for looks. It keeps the selector turning smoothly and holds up to sweat, solvents, and years of range time without pitting or dragging. The build quality is a step above the basic selectors that ship in a lot of budget lower parts kits.
Fit and Compatibility on the AR-15 and AR-10
The TRSSAB is built to work across the platform. It fits any semi-automatic AR-15, AR-10, or AR-pattern pistol caliber carbine that accepts a USGI-style safety, so one part covers most of the rifles in a typical safe. Because it follows the standard footprint, installation is a straightforward drop-in with basic tools, and the right-side lever is held in place with a small retention screw.
Wilson Combat has been building custom pistols, rifles, and parts out of Berryville, Arkansas since 1977, and they've earned their reputation for getting the details right. If you're upgrading a home build or refreshing a factory rifle, this is an easy, sensible improvement to how your AR handles.

Frequently Asked Questions
Will the Wilson Combat TRSSAB fit my AR-15 and AR-10?
Yes. It's designed to work with any semi-automatic AR-15, AR-10, or AR-pattern pistol caliber carbine that accepts a USGI-style safety. If your rifle runs a standard mil-spec selector now, this drops right in as a replacement.
Is the TRSSAB selector hard to install?
Not at all. It's a drop-in swap for a standard selector and goes in with basic tools, and the kit even comes with the Allen wrench you need for the right-side lever. Most folks have it done in a few minutes at the bench.
Why go ambidextrous instead of a standard single-side safety?
An ambidextrous selector lets you engage and disengage the safety with either thumb, which helps left-handed shooters and anyone who switches shoulders or runs different grip styles. It speeds up manipulations and just makes the rifle more comfortable to run. For a lot of builders it's one of the first upgrades they make.
What is the black nitride finish for?
The black nitride coating on the TRSSAB resists wear and corrosion, so the selector keeps turning smoothly and holds up to sweat, cleaning solvents, and heavy range use. It's a durable finish that keeps the part looking and functioning like new for years.
