Armaspec SFT45/90 Ambi Safety Selector ARM113 Red AR-15 AR-10

Description

The Armaspec SFT45/90 is one of those small upgrades that changes how your rifle feels every time you run it. Instead of picking between a short-throw or a standard safety and committing for good, this one hands the decision back to you. The steel core is machined with channels for both a 45-degree short throw and a full 90-degree throw, so you set it up the way your lower is cut and the way your thumb likes it. The red anodized aluminum levers add a pop of color that looks sharp against a black lower without being over the top.

What the SFT45/90 Red Brings to Your Build

This is a fully ambidextrous selector, and it ships with both a long and a short lever so a righty or a lefty can set it up comfortably. The movement is smooth with a positive, crisp lockup, so there's never a question about whether you're on safe or on fire. That short-throw 45-degree setting is the big draw for a lot of folks running it in the 45-degree position for faster, snappier transitions between safe and fire while training or moving.

Fit and Install on the ARM113 Selector

The SFT45/90 fits standard AR 5.56/.223 and 7.62/.308 lowers, covering both AR-15 and AR-10 style rifles running a mil-spec trigger. It drops right in where your factory selector sits, no gunsmithing needed. Torx screws and the matching Torx key come in the box, so once it shows up you can swap it in at the bench in just a few minutes. The core is steel with a phosphate finish and the levers are anodized aluminum, so it's built to hold up to real round counts.

Armaspec builds these in the USA and backs them with a lifetime warranty, which says a lot about how they expect this part to perform over the long haul. If you want ambidextrous control with the flexibility to run short or full throw on the same rifle, the SFT45/90 in red covers all of it in one tidy package.
