Strike Industries Safetly Selector Switch - Black

Very stiff and hard to switch on and off. Seems like other folks have had the same issue.

I may be a half a dozen of these the best ones on the market in my opinion

It was definitely tough to manipulate. I think the standard ExpoArms one is better. Maybe looks cool but its not crisp or easy to operate.

Quality/machining is great. I normally much prefer the 45 degree safeties for ease of returning to "safe" but, since you have the second pad, not an issue. Odin Works makes a similar product (45 degree, offset angled pads) and I personally prefer this for appearance/function. This lever is a little longer but does not interfere with my grip on the right (ambi) side. Also comes with button to cover the end of the shaft if using one-sided. The only issue I have is that the shorter pad (normal position) barely sticks out past the safety stop nub on the receiver, either to the sides or to the rear. The weapon I was initially going to put this on has a standard receiver with the safety stop nubs and I found it difficult to engage the safety because the smaller pad is mostly covered by the nub. I swapped it over to a weapon with a billet receiver without the nubs and really like it.
Bottom line is this a a really nice safety but best for receivers without the safety stop nubs.

The ambi safety selector seems to be very good quality. It was packaged extremely well.

The selector is very well made, much different than the stock ones.

Looks good and easy to operate
