Many people have been asking what these new pins look like so we put together a couple of pictures for you.
KNS Precision Inc has come up with their 2nd Generation Anti-Roll Pins. The revision came after some reports of broken hammer pins in pistol caliber uppers. Brooks at KNS waisted no time to revise what was aleady an excellent design by changing the hollow hammer pin with a solid heat treated SS pin. The reinforcement bars are even thicker than before and will not bend like previous versions. If you experience a broken pin, KNS will replace them with the Gen 2 parts needed to convert your pins to the new design.

If its alright with the good guys from Rainier Arms, here is a pic of my KNS 2nd Gen Pins.
 Very Easy to install in my stripped Lower, a piece of cake. Thanks Stick and Teknic (John). Regards, Nathan |

I appreciate the input, and if you get a chance, give your view of the pins, and how they installed for you. I think posts in general give better info if there is additional people with experience using the item. |

Starting off, the Pins are well made. The First Pin basically slid right in place with a firm push. I like the fact that the trigger pin can be oiled, nice little feature. the second needed alittle more force to put all the way in. Remember that you have the tension of the hammer spring, but two light taps from my rubber mallet put the second pin in place. Then install the two pieces that they may call "anti-walkout Bars" (I don't know the technical name). The pin has a Flat screwdriver kind of slot on each side that the bars fit onto.Then just simply install the two screws with an allen wrench, firmly, but not too tight. You get what I call a form of "insurance for your lower". I would recommend them to anyone that uses and trains hard with their AR's, especially for Class 3 Select-fire weapons. Hope this helps in some way. Regards, Nathan Ps. If I thought of it, I would have done a step-by-step Picture and review Thread. |

I love the set I got from John
  They're easier to install than the previous version, they also happen to be pretty good trigger finger "shelf" on the lower when the finger is not in the trigger guard, I put my index finger above the bar. I used the previous version's bars in the same fashion, the beefier bars of the new version are more comfortable and positive.  |

Denny at GTS had a few sets left when I spoke with him a couple days ago. No disrespect to John but I prefer the old design as well.

I have the 2nd gen problem...
I received my gen 2 from you today and they are blocked by the receiver near the mag release.  I will grind them down eventually, but FYI Superior arms lower. |

I got the upgrade parts from KNS and love the 2nd. gen. pins. I prefer the "look" of the 1st. gen. pins, but think the new design is a lot better. Eliminates 2 screws, (parts) and the hammer pin is solid like it should be. What lowers are the new style kits not fitting? Works great on my Mega.

If it's been shot, go with the .155. If it's brand new, the .154 will work.

I'm interested in buying a set; I have an AR that has not been shot very much (under 1,000 rounds), and I want this particular set; I figure .154 will work for me. Please IM me or email me so I can buy a set from you.
Thanks in advance.

Will the KNS Gen 2 anti rotational pins work with a colt lower that has the KAC match 2 stage trigger?
if so which size? thanks, chris |
|
|
|
Posted: 11/13/2006 11:47:45 AM EDT
[#25]
I believe the KAC trigger is the standard trigger size in which case you will need the .155 size if the rifle has been shot.
|

Posted: 11/13/2006 12:13:41 PM EDT

If it is a Colt lower my guess it has .170 pins. Did Colt ever make lowers with standard size pins? |
|
|
|
|
Posted: 11/13/2006 12:43:55 PM EDT
[#27]
OK, what's all this about using .1555 pins in lowers that have been shot? Why would the holes be worn unless said lower had a few thousand rounds through it without anti-rotation pins or had been run F/A? I don't get it. If the pins need to be .1555, why is the standard pin size on .154? I know we're talking microscopic differences here, but still. It's like saying all lowers that have been shot are now "worn".

What was the result? Did you also have the grooved trigger pin in your old kit? Not sure what you're saying, but you do know KNS will send a free upgrade kit don't you? Brooks is the shit!!! |

Sorry, that was my attempt at being funny. I was just saying that I could pretend that my current pins bent while in use in order to get the free upgrade. I only have two sets and they both have a groove for the trigger pin. I don't have any pistol caliber AR's currently, so I'm fine. |

I also had a problem with the length of the reinforcement bars (or the dimension of the lower) on an LMT lower. There was insufficient space at the raised area at the rear of the magwell for the reinforcement bars to lay flat. I removed a little material under the reinforcement bars forward of the hammer pin slot, and the bars lay flat. The material that I removed was minimal and on the underside of the reinforcement bars and is not noticeable. I also installed a set on a Stag lower, and the fit was perfect. I did not measure the reinforcement bars from the two sets and assumed that there is a dimensional difference in the lowers. It seems like a solid design. HAPPY THANSGIVING, FRIENDS. |

Pleasant surprise today in the mail, the KNS pin sets I ordered were the 1st Gen, but they sent me the 2nd Gen ones instead. Awesome
I'll try to post pics when I get them on my lowers.

We will send out upgades to ALL customers of our pins. We consider the upgrade part of our warranty. You keep your old trigger pin and screws, and we send you a new hammer pin and links. The old pins do not have to be damaged in any way. Just give us a call at 830-997-0000. We send them out FREE. No shipping and handling charges.

If you recieved a set of links that hit your receiver mag-well give us a call. We had a few sets early on that were shipped with a little longer link. There is a large variation in the distance of the pin hole to the magwell on many "Mil-Spec" receivers. The initial run of new pins were tested on several guns, but there are a few out there with a shorter distance to the magwell. If you ever have any problems with our products call us (830-997-0000) or our distributors. We will fix the problem or refund your money. All products have a lifetime warranty.

My only concern with the new pins is they are allowed to "float" from side to side. Is this a problem for anyone yet?

Iwas just about to post the exact same thing. I got my gen 2 pin set in last week and installation was easy. But did notice that there is side to side play, about a business card thickness. Is this normal? Lets us know or i'll call when i got a chance. RRA LOWER |

floating from side to side is not what causes receiver wear. The spinning of the pins is what causes wear. KNS has fired 35,000 simulated rounds with no significant receiver wear. Try doing that with regular pins.

I read somewhere that these are supposed to allow for easy lubing of the pins themselves? Can someone explain?
