Best Safety Selectors for AR-15: Top 3 Experts Picks

When thinking and talking about upgrades and enhancements for your AR-15 rifle, most of us tend to think about optics, stocks, or trigger groups. Very few of us consider the more mundane parts of an AR-15 that are prime candidates for upgrades. An example of these often overlooked parts is the safety selector.

The safety selector on your AR-15 may not seem like a part that needs a lot of attention. However, this seemingly minor part of your AR-15 is a key component of the trigger group. Many of us spend hours refining the function of our AR-15 triggers but never consider doing the same for the safety selector.

There are many good safety selector upgrades on the market. You can also employ tips and tricks to make the safety selector on your AR-15 work as smoothly and as effortlessly as your trigger. In this article, I will look at the functions of the safety selector, some common ways to improve your safety selector’s action, and some of the best-upgraded safety selectors you can find on the market. 

Safety is the Key Word

The safety selector on your AR-15 is a simple arrangement. The selector lever on the left side of the AR-15 receiver has two positions. When the lever is in the horizontal position, your AR-15 is in safe mode. In this position, the safety engages the trigger and prevents disengaging the hammer from the seer. The hammer cannot move forward and strike the firing pin with the safety engaged.

Move the safety lever to the vertical position pointing up and the safety bar disengages the trigger allowing your AR-15 to fire. On AR-15’s the trigger must be pulled each time you fire a shot. 

You must remember that the safety selector on your AR-15 is only a small part of safe gun handling. Your AR-15 is safest when the magazine is out of the rifle and the bolt is open. When you aren’t actively at the firing line, this is the best condition to keep your AR-15 for everyone’s safety.

Safety Selector Upgrades – What is Available

In the world of AR-15’s, the variety and depth of upgrades and accessories are staggering. The choices of safety selectors for your AR-15 is much the same. However, there are some upgrades for your safety selector that merit more attention.

Ambidextrous Safety Selectors

There are many lefthanded shooters in this world. The stock safety selector on an AR-15 is only operable from the left side of the receiver. Lefthanded shooters find this awkward as there is no way to manipulate the stock safety selector with their thumb.

Serious shooters often train using both hands to manipulate their AR-15. Shooting with their weak hand is a good exercise to improve your overall capabilities. If you train with your week hand routinely, you will also find the stock safety selector when firing from your left shoulder.

These scenarios make the addition of an ambidextrous safety selector almost a must for many shooters. There are several variations on the ambidextrous safety selector, and we will look at several in this article.

45 Degree Safety Selector

Stock safety selectors on most AR-15’s require the safety to be moved 90 degrees from the safe position to the fire position. For some shooters, this range of movement is excessive and time-consuming. Shooters with smaller hands may find it necessary to shift their hand on the rifle grip to make this movement.

Safety selectors for your AR-15 are now available that reduce this range of movement. To disengage the safety into the firing position requires only a 45-degree movement. The 45-degree safety selector cuts the travel distance of the level in half and makes a move quicker. 

In most instances, the addition of a 45-degree safety selector doesn’t require any changes to the trigger control group or the receiver. The 45-degree selector is a drop-in upgrade easily accomplished by most ar-15 owners.

What to Look for in an Upgraded Safety Selector

As I considered the many upgraded safety selectors on the market, there are several factors I considered. These are, in my opinion, the critical ingredients to a top of the line safety selector. You should make your own decisions about what is most important to you when selecting your upgraded safety selector.

  • Fit and Finish The fit and finish of the safety selector are critical. Poor workmanship or less than stellar machining can mean more problems than you might think. Look for these critical defects that indicate poor workmanship or machining on the safety selector.
  • Clean edges – Examine the edges of the safety selector. The edges should be clean and well defined. However, there should not be any razor-like surfaces. Look for burrs or ragged spots indicating poor machining and finish.
  • Straight and true – The selector lever and the shaft should be square and true. There should be no cants, bends, or curves in the shaft.
  • Sizing – One major problem with aftermarket parts is the sizing. If the aftermarket part, such as a safety selector, doesn’t meet the tolerances set out in the specifications, the safety selector may not fit correctly. A poor fit can cause a safety selector to be loose and wobbly or so tight it is hard to operate. 
  • Material – I prefer safety selectors made of the same sort of aluminum alloy used in the other parts and the receiver. Avoid polymer safety selectors. I have found that these parts wear too easily, leading to the safety selector’s failure to perform its functions. 
  • Price – Price is usually the least of my concerns when choosing an upgraded safety selector. Compared to the other parts of your AR-15, even the most expensive safety selectors are relatively cheap. Why skimp on the part of your rifle that performs such a vital function.
