The Battle Arms Development Combat Ambidextrous Safety Selector offer traditional 90-degree throw. This AR-15 ambidextrous safety selector is also compatible with AR-10 lower receivers, so you can use it on all your favorite builds. The BAD-CASS safety lever differs from other models in the way that it attaches to the center bar. The dovetail lever attachment reduces the stress on the screws allowing for a much stronger and more secure lock up and if properly torqued to 5 in-lbs should never come loose unless you want to swap levers to one of the many different designs and colors. This set comes with one extended and one short lever with an anodized black finish. If you have a standard AR-15 safety selector and want the ability to quickly manipulate your rifle from either side, the Battle Arms Development Ambidextrous Safety Selector is the one for you.

A BADASS for less $


This is a great selector. Smooth operation, positive retention in safe/fire settings. It’s essentially a BADASS for less $ with different styling. It would be nice if it offered <90° throw, but since it comes with a short lever there won’t be a problem with it digging into your hand like a full-size 90° ambi can. I bought mine under the name “Alethia”. Not sure why the change in branding. Highly recommended.

Best Selector I've Used So Far


This is my favorite ambi selector by far. Beautiful machining and finish, no sharp edges, and wide paddles makes flipping the safety a pleasure. I have tried the Strike Industries Flip Switch and Phase 5 Tactical 90 Deg switch; the SI is too narrow and hard to flip, plus the machining is hard on the fingers, and the Phase 5, while wider and much easier to flip, still has some sharp edges. The Battle Arms selector simply looks classier, and works better - so much more comfortable to use.
<br>Oh, and the PA guys are amazing. I'm blessed to live locally, so my fix is always a 15 minute drive away.

What a beaut!

I made this purchase during the Black Friday sale and am NOT disappointed! The product is rugged but lightweight, definitely an improvement over the traditional safety selector on the AR platform. I would definitely recommend this product to a friend of family member, Primary Arms never disappoints, and their customer service is ALWAYS top-notch!
