Great seller, fast shipping, excellent communication

This ambi switch gives me good purchase without being overly large. It's great that it comes with the ability to make it single sided out of the box even thou I didn't use the extra piece. All parts are well machined without flaws or tool marks. Yes the switch was very stiff when installed. Put a little oil or grease in the appropriate hole then spend the time to work it and it will become easier to flip. I prefer a POSITIVE 60 degree throw.

Bought one set earlier this year and can't get it to work - yep, I've installed other selector switches into the same lower and they have all worked flawlessly. Looks like the milling was poorly done. First product from Strike that leaves me dissapointed!

I am a huge fan if SI products, i have many of their products and have always been very satisfied. I was a bit disaaapointed how stiff it is to flip to fire, but it is smooth from fire to safe. I am a lefty and this is my first ambi switch...may go to a different SI switch in the future.

The edges on this selector are sharp. They put cuts on my thumb whenever I use it. I had to file down to edges so it would stop slashing up my finger. Also the machining on the selector detent holes catches on the selector detent causing the selector to get stuck or be extremely hard to switch on and off. Horrible. Do NOT buy!

Easy install and perfect fit in mil spec lower. The detent spring will cause extra tension and cause some drag. I removed 2 coils from the spring and everything was perfect. Very good fit and finish. Definitely good kit for a lefty like me.

First off, man this thing looks good! The ends fit snug and solid. I'd recommend a little blue loctite on the screws when installing. Personally I love the slightly shorter legs as they don't get in the way of the grip. I even let my 8 yr old son try it out after reading that first review and he didn't seem to have a problem using this selector at all. As for it being stiff... like the last guy said just trim your spring and it'll be smooth as butter. (again, that's your parts kit spring, nothing to do with this SI part). Oh, and I'd like to add that Wing got my order to me from Cali to MS on the 3rd day. Awesome shipping!

Previous review said there wasn't enough length to it, with average size hands. I have small to avg size hands and fingers, and I reach the switch VERY easily on both sides. It fit perfect in my Aero Precision Gen 2 lower. It moves perfectly from position to position. I did however need to trim the detent spring down a tad. This isn't the fault of the switch in anyway, as it doesn't come with a spring/detent. After a lil trim, it is by far the smoothest safety I've used. Couldn't be happier.

I have several SI parts and accessories and they all function well and look great. However, this selector left something to be desired. Replaced my factory mil-spec selector with this and I wish I could give it five stars but it is VERY stiff. I've heard others have this problem as well (unfortunately AFTER I purchased it). Also, SI advertises more "meat, better ergonomics, and a good positive purchase." It does have more meat but I wouldn't say it is more ergonomic. I like the thickness of it but the decrease in length left my thumb wanting more. I have normal sized hands and semi-long fingers and run a factory A2 grip and I feel myself reaching/searching for the selector due to its shortness. I also had a bit of trouble getting one of the levers onto the center pin because the space cut out for the lever was just a little too small, I did get it on however. Oh and did I mention it's VERY stiff. Fast shipping by Wing Tactical though, will be using them again.
