Description
Swapping out a gritty factory safety is one of the quickest wins on an AR build, and the Timney 49'er makes that upgrade a no-brainer. It gives you two throw options in one part: run it as a traditional 90-degree lever, or set it up as a 49-degree short throw for faster, thumb-friendly manipulation. That shorter arc means your thumb travels less distance to go from safe to fire, which a lot of folks running a high thumb-forward grip really come to appreciate.
What Sets the 49'er Apart
This one is precision-machined from heat-treated steel, so it holds up to hard use without feeling chintzy. Timney includes a carbon nitride coated safety plunger along with a fresh spring, and that combo is where the smoothness comes from. The engagement is positive and tactile, giving you a clean click into safe and fire every time instead of the vague, sticky feel a lot of stock selectors have. It's ambidextrous out of the box, so lefties and righties both get a lever where they want it.
Setting Up Your 49'er the Way You Like
Not everyone wants a lever on both sides, and Timney thought of that. The 49'er ships with an end plate that lets you pull the ambidextrous arm and run it as a single-sided safety instead. That flexibility is handy whether you're building a clean, snag-free setup or you just prefer keeping the offside smooth. It's a true drop-in part that works with any Mil-Spec lower receiver, so installation is straightforward with basic tools and no fitting required.
Backed by Timney's lifetime warranty and made in the USA, the 49'er is a small part that punches above its size. If you've upgraded the trigger and want the safety to match that same crisp feel, this is the piece that ties the fire control together on an AR-15 or AR-10 build.

Frequently Asked Questions
Can the Timney 49'er be run as a single-sided safety?
Yes. The 49'er comes with an end plate that lets you remove the ambidextrous arm and run it as a one-sided selector. That gives you a cleaner, snag-free setup if you don't want a lever on the offside. It's a quick change with no special parts needed.
What's the difference between the 90-degree and 49-degree throw?
The 90-degree throw is the standard AR safety motion most people are used to. The 49-degree short throw cuts that arc down so your thumb travels less to move between safe and fire, which speeds up manipulation. Both settings are built into the same part, so you can set it up whichever way you prefer.
Will the Timney 49'er fit my AR?
It's a true drop-in part designed to work with any Mil-Spec lower receiver, so it fits standard AR-15 and AR-10 builds. Installation is straightforward with basic tools and requires no fitting or gunsmithing. If your lower is Mil-Spec, you're good to go.
Why does the 49'er feel smoother than a stock safety?
Timney machines it from heat-treated steel and includes a carbon nitride coated plunger along with a fresh spring. That coating and the precision surfaces are what give it the smooth, positive click you feel going into safe and fire. It's a noticeable step up from the vague feel of most factory selectors.
