It's only about $6 @ Brownell's. Not too much $$, if you don't like it. Besides, Brownell's will always give you your money back, if you don't like it.
Just bought one and a ambisafety. I am going to see which one I like better. I figured the star at the end will help me engage it with my short thumbs. We will see
Installed my RRA star safety yesterday. I have to say it is easy to engage even though I have short thumbs. Downside is that it sits a little far off the receiver and travels far so that when you turn it to "safe" it nicks the top of the stop. Oh well, maybe I will "have to" duracoat it now
