Description
Southpaws and anyone who runs their rifle from both shoulders know the frustration of reaching over the receiver just to flip the safety. The CMMG Ambidextrous Safety Selector Kit fixes that by giving you a lever on each side of the lower, so the safety works identically whether you're a right- or left-handed shooter. It's a three-piece assembly that drops right in where your factory selector lives, built from steel with a clean black finish for the kind of durability CMMG is known for.
What the CMMG Ambi Safety Kit Brings to Your Build
The selector uses a standard 90-degree throw, so the muscle memory you already have carries over with no relearning. The levers are mil-spec style with grooved surfaces for a positive grip, and there's enough real estate to work the safety with gloves on or in low light without fumbling. Feedback from folks who've run it consistently points to a solid, smooth feel with a confident click on and off. It fits standard AR-15, M16, and M4 style lowers, and plenty of owners have dropped it into AR-10 platforms too.
Installing the AR-15 Ambidextrous Selector
Installation is about as straightforward as AR upgrades get. The kit comes with the mounting screw and a hex wrench, so you've got what you need to get it in without a trip to the gunsmith. A light dab of grease on assembly keeps the action smooth, and once the screw is snugged down it tends to stay put. If you're building a lower from scratch or refreshing an older parts kit, this is an easy swap that adds real usability.
Bottom line, it's a well-made ambidextrous selector at a sensible price point, backed by CMMG's lifetime quality guarantee. For anyone teaching new shooters, running the gun from either side, or just wanting cleaner ergonomics, it earns its spot in the build.

Frequently Asked Questions
Will the CMMG ambidextrous safety selector fit my AR-15?
Yes, it's designed as a drop-in replacement for standard AR-15, M16, and M4 style lower receivers that use a mil-spec selector. Many owners also report fitting it successfully into AR-10 platform rifles. It uses the same 90-degree throw as your factory selector, so the fit and function stay familiar.
Do I need a gunsmith to install this safety selector kit?
No, installation is a straightforward job you can handle at home. The kit includes the mounting screw and a hex wrench, so you have the hardware needed to swap it in place of your existing selector. A small amount of grease on assembly helps keep the action smooth and the screw seated.
What is the CMMG ambidextrous safety kit made of?
The selector is built from steel with a black finish, which is what gives it that solid, durable feel owners tend to mention. The levers carry a mil-spec style design with grooved surfaces for grip. It's made in the USA and backed by CMMG's lifetime quality guarantee.
Can I run this safety with gloves on?
The levers have a good amount of surface area and grooved texturing, which makes them easy to operate with gloves or in low-light situations. The 90-degree throw gives a positive, audible click on and off, so you always know the status of your rifle. That makes it a handy setup for training or duty-style use.
