KNS Precision Non-Rotating Pins AR-15 .154" - Black
Ratings & Reviews
Holes in pins are for oil
The 2 small holes in the 2 pivot pins are to trap oil, which keeps the hammer and trigger pivoting on the pins nice and smooth. During installation, put 2 small drops of your favorite lube. 1 on each side of the hammer and trigger (next to the springs), and the oil will find its way into the holes.
Necessity with Spike's trigger
by Seth -
I really didn't want to use this. It's just extra weight and disassembly, etc.
<br>Spike's (and maybe others) need some device to keep trigger pins from walking out.
<br>Their hammer spring seems a touch wider than others. The ears not only go closer to both sidewalls, but the half circle cuts come up too high and prevent the hammer spring from dropping into the side notch on a trigger pin.
<br>(I still haven't figured out the two holes in the middle of the trigger pin!)

Highly recommend for any person to use. Originally I had a Spikes lower parts kit. The pins would gradually slide to the right while shooting. I noticed that I could push them back in with just my fingers. This took the rotation and movement out of the trigger and hammer pin caused by firing. No issues so far. And easy to install.
Minor fitting required
by Phil -
These are excellent additions to an AR, especially if you a drop-in trigger. However, both receivers I put these in they have a small gap of a millimeter or so when tightened fully. Small washers will solve this

Love em. Have them on all my ARs.
Great item to upgrade your rifle
This is my second set of KNS pins. I highly recommend you use them when upgrading your trigger or just need a bit more security holding in the trigger pins. Great product delivered by the always great Primary Arms

Excellent parts, easy installation.Fast shipping:)
Work as they should
These pins look great and work well. A nice inexpensive way for a cool custom look. Plus they do keep your trigger pins from rotating.
These look great
Not sure if they work yet or are really needed for a semi auto AR, but they sure look cool. Saw them on sale and jumped on 'em. PA shipping was super fast as always.

A must for poorly drilled pin holes which are more common now will all the 3rd tier suppliers.
As everyone has said they work great and install easy
Nice add on
Bought these after I noticed my pins were starting to walk out. These look great plus will keep the pins in place.
super price and super product w PA customer service!
Perfect fit and price
shipped and arrived faster than I expected, great price- easy installation, happy guy.
Item seems to be very well made. Probablynot needed, but my trigger pin would rotate 1/2 turn every cycle. Thanks to Primary Arms for fast shipping and decent shipping rates.
