AR-15/M16 NON-ROTATING PIN SET Reviews & Ratings

Redesigned hammer pin and anti-rotation links provide the strongest possible system to eliminate pin rotation, and will withstand the additional force exerted by 9mm conversions and suppressed .223 upper receivers. Helps prevent wear to receiver holes, which is especially important for increasingly-valuable M16 and pre-ban receivers. Notched hammer pin locks into slots in the anti-rotation links; trigger is secured with locking screws, and includes lube ports so adequate lubrication reaches the trigger. Anti-rotation links fit on the outside of the receiver to prevent all movement. Pins are CNC-machined, centerless ground for uniformity and heat treated for durability. Available in Standard .154", Oversized .155", and .170" for larger receivers. Oversized Pins help improve accuracy and trigger control by tightening up any trigger slack that may exist in worn or new receivers. Standard-sized pins drop-in and require no modification to the receiver; oversized pins require the use of the 3.95mm Reamer (available separately).

SPECS: 416 stainless steel pins. .900” (22.8mm) long, .154" (3.91mm), .155" (3.93mm), or .170" (4.31mm) diameter. Set includes (1) hammer pin, (1) trigger pin, (2) screws, (2) anti-rotation links, hex wrenches, and installation tool. Anti-Rotation Links - Steel, Parkerized finish. Retaining Screws - Steel, black oxide finish.

Works well...

I am a certified AR-15 / M-16 Armorer and work as an armorer for my police department. I purchased this pin set for a carbine build I am doing. packaging was okay (plastic bag) but came with no instructions other then a poor picture. installed nicely with no problems. quality is good. I only gave 4 stars to to lack of instructions to install.

Look at description not picture

This kit comes .1555 pins, the side plates and screws, NOT the slightly larger pins and reamer as pictured. I used this to tighten up a JP trigger that was installed in an old receiver that had at one time had oversized pins. The slop made for an inconsistent trigger pull. The KNS kit took care of it, but don't expect miracles. If you are doing a new build and have spec trigger parts, save your money - this won't do much for you.
