AR15/M16 High Tech Non-Rotational Hammer/Trigger Pins with Retainers

This is the hottest setup we have seen for hammer/trigger pins.  These pins are made of stainless steel with holes for lube.  The pins are threaded on each end.  These are available in two diameters, .154” for standard use and .1555” for a tighter fit or receivers with wear in the pin holes.

Once the pins are in place in the receiver you simply place the pin retainers over the threaded holes in the pins and secure them with the screws provided.   Once installed your hammer/trigger pins will no longer rotate and cause un-necessary receiver wear and the pins also cannot “walk out” to due weak hammer or trigger springs.

The little bullet shaped object in the picture is the EZ install tool and is screwed into the threaded end of the pins.  Due to the taper on the EZ tool pin alignment is a snap.  All necessary tools come with the kit.

I have used these pins on the lower pictured with our Rock River Arms 2 Stage Match Triggers and they fit perfectly and there is no wobble in either the hammer or the trigger.

I recommend these very, very highly.  They eliminate receiver wear, have superior ability to hold lube, stainless steel and are anti-walk.  

Retail price is $32.00 a pair, GTS price is $29.95 + $3 shipping. Standard Pins or Oversize.

Thanks for your comments.  I think these are the best pins you can put in your AR or M16.  Why cut corners when there are improvements like this available so cheap?

denny

They will take up all the slop and play of the standard trigger pins and make your JP work better due to closer tolerances.

Dano,

Nonsense.  The grooves are there for interchangeability.  As to strength I have only seen two trigger group pins that were broken in 20+ years of working on M16s, not ARs, M16s that were worked hard. As pins are pins they may have been of inferior manufacture.  I have never seen a broken pin in an all Colt gun.

I have seen many, many worn pin holes in receivers due to pin rotation.  

As to friction and lock times, the lock time is determined by the distance the hammer travels, the spring weight and the hammer's mass.  The amount of fricition between the J spring and the pin has so little to do with lock time it is negligable.  Most people prefer to keep the hammer where it belongs.

These pins are precision ground on aerospace equipement and are as near perfectly round as humanly possible and made of stainless steel.

I would much rather keep the hammer where it is supposed to be in relation to the rest of the parts in trigger group than worry about some theoretical friction issue.

Denny

Dano,

The pins are not available without the grooves.

Gee,  I liked the simple question better[:D]

Denny

I check the oversize in about 12 hammers and 9 triggers in stock, factory Colt and Bushmaster and they fit fine.  One trigger was a little bit tight but after a little twisting it fit too, snug, but I believe that was due to a small amount of finish I could see in the pin hole.

You will have not problems with the oversize pins and factory parts, if the parts are spec.

Denny

The standard size is just that, the standard mil spec size.  To turn it around, why would KNS ONLY make oversize?

The standard size fit the standard size holes in your receiver.  The over size are a very tight, read use a light, soft hammer to tap them in, fit in a non-worn receiver.

Most M16s are used by the military and they require tolerances for dirt, powder residue, gunk, crude ect. to function under adverse conditions.

Some folks tend to think of this weapon design as a civilian owned target gun that is lovingly cared for.  Many ARs are used hard by civilain shooter and military alike as well as PDs.  Many shooters choose reliability over a match grade fit on the parts,  same with 1911s.

The only way to have a product for both groups is to offer two sizes.  Hope this helps.

I personally use the standard size in all my guns except the old PWA preban receiver I am using to build the pre-ban from hell.  [:)]

Denny

You are welcome.  I am now using these pins in 100% of our builds.  There is nothing even close to this quality on the market.

Denny

There are no special tools required.  Only the two allen wrenches and they are supplied with the pins.  The EZ is just for installation and is not required, it is just included to make the job easy and it is really, really easy.

I can install a RRA 2 stage in about 10 minutes with these pins and I am very careful and take my time on each step.

Denny

I would say if ya got room for a set of punches and a hammer two 1/16" allen wrenches should not add much to your load [:)]

Denny

As to the J groove.  I just opened and installed a new set of the .15555 oversize pins in my PWA preban lower when I was installing a new RRA trigger and guess what?  The over size set DOES NOT HAVE THE J SPRING GROOVE IN ONE PIN!!!

Denny

Or,

It was great visiting with you and you were very kind to take time out of your trip to stop in.

How did ya like the machinegun vault?

Denny

Charles,

You can use the pins without the bar but you would sacrifice the non-rotational feature of the system.  The screws lock the pins to the bar and that is what stops the pins from rotating.

Denny

Orddy

Pleasure having you down.  Any other ARF members who are in KC please stop by.

Denny

benbob,

Thanks for the insights.  I agree if your lower is cast these are a must if you shoot much at all.

Forged lowers will never wear in the pin holes if you start out with the KNS Pins or get them in before wear starts.

If your AR has a crummy trigger pull many times it can be out of round pins.  The stainless KNS pins are precision ground perfectly round and will not drag on the trigger.  Many guys have emailed me saying that their trigger pulls improved a great deal just by using the KNS hammer/trigger pins.  The anti-walk feature is a definate plus also.

For the M16 guys they are making a pin for the auto sear also.  I have had plenty of these walk out.

Denny

You may be surprised how well your trigger works without any mods just by installing these perfectly round stainless steel pins.  

Try your stock trigger before and after you install the KNS Pins.  Sometimes there is a great improvement other times very little if your stock pins are in spec.  But most times there is improvement just due to the fact these pins are precision ground round and are polished stainless with no parkerizing or finish on them.
