Great! now offer it in 45*. - JP Enterprises Adjustable/Reversible Safety Selector Kit

I got this as part of the JP cassette trigger kit. By itself, it’s not worth $70. Paired along with the JP trigger? It’s a “matched” set. It has a special groove cut to match the JP trigger, making it solid when you pull the trigger with the safety on, it’s literally engaged.

If I was to guess, theres not a 45* option available because it’s very easy to manipulate compared to others.
