Good Pins, Bad Screws

by -

These are definitely not KNS quality. I'm not a brand snob, I just expect my parts to function. That said, I got mine on sale for 15 bucks. At that price point, I can look past the fit and finish. The button head screws that came with my 2 sets were garbage. The heads stripped out immediately and the blue goo was useless. I hit up my local orange box store and grabbed some new screws (Socket cap M3-0.5 x 6mm) . Perfect fit, .39 cents a bag. They stick out a bit more, but it gives my lower more of an industrial look, plus it gives my finger a place to rest away from the trigger. Also, they are plain allen key heads, so no weird star or torx bit to strip out while tightening. I don't have an ambi bolt release on this particular AR, but from the looks of it, the socket caps will be in the way if you try to use one. All in all, they work as they are supposed to, after spending less than a dollar on new screws and I already had the blue goo in my tool box.

Well worth the price when on sale.

Out of the 4 screws (torx head) I had one of them strip out. Not a big deal. It wouldn't have happened if I had taken the time to get my other wrench out of the tool box and use it on the opposite end screw head to counter the tightening force instead of just holding on to the lower and then the supplied torx wrench wasn't square with the screw head.<br>I looked high and low on PA's website and on Guntec's website to find out what the diameter of the pins were but never found it. It's not on the packaging either. So for those of you still wondering the pins are 0.154 so you can use them in both 0.154 and in 0.156 holes if you like. They really need to add this to the description.<br>As for the quality like I said, I am pleased for the price. I like the addition of a screw in "bullet" shaped piece that you can use to guide the pin into tight holes and make it easier to align the trigger holes with the receiver holes. That was a well thought out item.<br>I would buy again.

Awesome set


I got these for my build, they work perfect, I had to remove them once to realign my trigger, (Fostech echo sport) no stripping or any issues. I highly recommend, plus PA is knocking out of the park on ship times
