Mil-spec safety selectors and many of their “upgrade” counterparts are less than ideal for many operators. For those of us who want a more responsive, easier to use safety selector there are a few choices on the market that will do the job. The 45-degree safety selector has become a very popular drop-in upgrade on the tactical arms market, and Ambidextrous selectors are also increasing in popularity. The Armaspec ST45 is one of our favorite options in the Ambi safety selector category.

Satin Smooth Movement, Crisp Lockup

The Armaspec ST45 operates exactly as you want it to. Its easy to reach levers and smooth movement makes position selection a natural, fluid movement for the operator while it locks up cleanly, leaving you no doubt about your safety status.

Armaspec ST-45: 45-Degree Design

Armaspec didn’t just make an adjustment to an old selector and call it good. The Armaspec ST45 is designed specifically to work with receivers marked for 45-degree fire selection. The intent in design assures you that this safety selector works as intended every time, no guesswork involved.

Easy Installation, Ambidextrous Operation

The Armaspec 45 Degree short throw Ambidextrous 45 Degree Safety Selector is easy to install in place of your factory safety selector. It features a steel core that marries to aluminum levers with Torx screws. Armaspec even includes the proper sized Torx key to get you from your mailbox to the range that much faster. Once installed, the ST45 operates easily from either side of the receiver for intuitive use in the field by a variety of shooters in variable circumstances.
