Product description
Affordable 45 Degree Ambi Safety
The ST45 is an ambidextrous 45 degree safety selector for the AR10/ AR15 platform. Instead of having a full 90 degree rotation to disengage the safety, this selector is set to fire at around the 45 degree point. This allows the operator to flick the lever to disengage from safety. This safety selector is incredibly smooth and has a super crisp lockup. It’s recommended to use with firearms with the correct “FIRE” markings on the receiver to match the 45 degree fire position of this safety selector. It can be used on any mil-spec lower, but operators should pay attention to where the safety will fall in relation to the markings.
• Torx screws and Torx key included.
• Fits AR 5.56/.223 and 7.62/.308
• Aluminum Levers / Steel Core
• Made in U.S.A
• Lifetime Warranty
Customer reviews 5
Verified buyer cljns54 · This is an update to the original one star review. After the customer support guys at AT3 saw my review, they immediately reached out to me to correct the problem and to make sure I was a happy customer. I can tell this is not their first rodeo. They gave me the option of replacement, refund to use on a different product or just a refund to my card. I choose a replacement because I have had these ambi safeties before and know the one I got was an exception and not the rule. AT3 tactical did not disappoint. A replacement was shipped immediately and the fit, finish and function was what I was used to getting from Armaspec. I was already a fan because I'm never had a problem with their products. But this rare event let me know that behind the great deals is a dedicated support team should you ever have an issue. Excellent service after the sale. I am not only a fan but a lifetime customer. Buy with confidence!
AT3 Tactical · Thanks for the detailed feedback, Clint. Sorry the Armaspec ST45 felt gritty with rough mill work—quality issues like that shouldn't slip through QC. Please reach out to our support for a return or alternative like CMMG. Your input helps us improve!
AT3 Tactical · Thank you for your detailed and honest feedback, Clint. It’s disappointing to hear the Armaspec ST45 Ambidextrous Safety Selector didn’t meet your expectations, especially given your extensive experience with ambi selectors. Your observations about the rough mill work and narrow detent channel are valuable and highlight issues that should have been caught in quality control. We appreciate your thoughtful review and suggestion for potential filing as a salvage option. Please feel free to contact our support team if you’d like assistance with a return or alternative recommendations for a smooth, short-throw ambidextrous safety selector. Your input helps us improve and better serve customers like you.
