CMMG Selector Safety for AR-15 - Precision Machined Fire Control Component
- Firearm Group:
- AR Platform
The CMMG Selector Safety for AR-15 is a precision-machined fire control component built to replace a worn or damaged safety lever on your rifle. If you're running a stock AR-15 platform gun and need a direct mil-spec replacement or an upgrade to a single-sided safety, this selector gives you a familiar 90-degree throw operation that works with standard AR controls. It's the kind of part that disappears into your rifle—exactly what you want from a safety mechanism.
This selector is engineered to meet or exceed mil-spec standards, so you're getting the same durability spec'd for military and law enforcement rifles. Whether you're building a new lower receiver, doing preventive maintenance on a rifle that's seen heavy use, or just prefer a single-sided lever for your shooting style, this is a no-fuss, reliable upgrade. CMMG's precision machining means tight tolerances and consistent fitment across AR-15 platforms.
Installation is straightforward for anyone comfortable swapping fire control parts—no special tools required beyond basic AR-15 armorer knowledge. It's the kind of small upgrade that adds up when you're optimizing your rifle for reliability and ergonomics.

Frequently Asked Questions
Is this selector compatible with my AR-15 lower receiver?
Yes, this CMMG selector is designed for standard AR-15 platform rifles. It replaces the factory safety lever and works with mil-spec compatible lower receivers.
What does 90-degree throw mean?
The 90-degree throw is the standard arc the safety lever moves from the fire position to the safe position—the same motion you're used to on most AR-15s. This selector operates on that familiar 90-degree angle.
Does this meet mil-spec standards?
Yes. CMMG engineered this selector to meet or exceed mil-spec requirements, so you're getting the same durability and tolerance standards applied to military-issue rifles.
Can I install this myself?
Installation requires basic AR-15 armorer familiarity and standard tools—no specialized equipment needed. If you're comfortable working with AR fire control components, you can handle this swap.
