Happy with this kit, for the price of most ambi safety setups you get a whole lower parts kit minus grip and fcg. The downside though is the pivot and takedown pins are extremely tight. I sanded the end of the detents so they would be round and slide better, but they are still very tight, to the point where I need to tap them out with a punch. Still, for the price this is a good kit. I'm very happy with the ambi safety. It functions well and looks nice. May replace the pivot and takedown pins further down the road.

Solid LPK. Everything fit in my Aero Precision lower with no issues. When you consider it comes with a short throw (45 degree) safety and anti walk trigger pins, it’s really a pretty good value. Only issues is this version does not come with a grip screw, so keep that in mind.

Very good product. Everything fits perfect on my ar15 lower build, the finish is nice. The safety 45 degree option is a plus. The stainless steel buffer tube detent is a plus. Will buy another for my next lower.

Here's the deal. The bolt catch, mag catch, and anti-walk pins are all good. No problems with them… The problems I do have are with the takedown pins, and the ambi safety. First the takedown pins… They are complete trash. Both were extremely stiff to the point where the rear pin would not move AT ALL, and the pivot pin got bound up after a few function tests, and then quit moving altogether. I removed both of them, and will probably throw them in the garbage, and replace them with some Strike takedown pins… Now the ambi safety… It's not horrible, but it doesn't have that nice, responsive click that you want from a safety. It's very mushy, and stiff at the same time, and doesn't give that nice audible click unless you really crank it… Given that I'm a lefty shooter cursed with the Devils Hand, this safety was my main reason for purchasing this LPK because it's one of the few out there that actually come with an ambi safety. I really wanted to like this kit, but honestly I'm probably going to replace safety with something else, and give this one to one of my friends… So that sucks.

I recommend this kit, it's awesome. Fit and finish of the parts are great. The anti-walk triggers pins are a nice bonus. The front and rear takedown pins provide a nice and tight fit. The mag release button is a little deeper than a milspec mag release button which makes easier to use in my opinion.The ambi safety is nice as well. It's 45/90 safety, so you will need to pay attention to how you insert it into your lower. Make sure the safety detent engages the correct groove. The safety tumbler has two grooves on the right side, a short one for a 45 throw safety (need a lower that is capable of doing this) and a longer groove for the regular 90 degree safety throw. Additionally, for my build, I needed to install the safety before the trigger (Hiperfire).I used this kit on an Aero Precision stripper upper and lower that I put together.Overall, I'm happy with the results. Quality kit at a great price. Some safeties alone cost more than this kit and the Armaspec kit comes with an ambi-safety.

The "Kit" comes with everything but the Fire Control(Trigger) and was just what I wanted.The red accents were a great complement to the added red lettering to my Integrity lower.One issue was that the stainless steel detent pins for the Take-down Pin and the Pivot Pin needed alteration to round over the nose of the pin where it contacts the actual Pivot and Take-down Pins to enable the pins to be pressed out without great difficulty.
