Easy Install everything went together perfectly. Used this with a RA-140 Trigger by putting in the KNS PINS and then releasing the set screws the trigger pull went from 4.5 to 4 lbs. happy with the product and took the weapon to the range and everything worked great.

This is a very tight fit, but it really stiffens up the trigger. I'm not going to order this size anymore, but these are the best pins i've used. The difference in trigger feel is worth it alone. I can't believe that people rely on the standard designed pins.

I’ve used KNS pins on all my builds. I always make sure I have a set of .155 and .154 pin sets on hand. I’ve found many lowers accept the .155 pins with no drama. Even quality parts from Aero and Noveske have varied between .154 and .155.

Couldn’t possibly have been simpler to install these pins! Make sure you have a proper punch and small rubber mallet. Highly recommend this product and will be buying more of these for future AR builds.

I had no clue whether .1555 or .154 was what I needed, so I bought .1555 pins. Wrong decision. They would not fit in a new high-end lower, not even close. I was able to put them into a Sig MPX and wow did it tighten up the trigger system. Also, high bolt speed on the MPX eats pedestrian trigger groups, so I was happy when they fit. I ordered .154 pins for the other and all is well. Quality, fit and finish are excellent, everything is good about the product. They are cheap and add life to your lowers.f

I use KNS anti-rotation pins on every rifle build. AR platform rifles have an aluminum reciever and steel pins. Something is going to wear eventually. Why not minimize the potential for failure? Its inexpensive insurance against walking pins and oblong pin holes.
