We'll I went ahead and did it. It's very smooth and less drag on the side of the frame. The trigger pull is still heavy but I'm happy with the results of 15min of work.



I'll post pics up later today

Did you try the 4.5 # trigger spring 00stormbringer posted a link up about ? That looks interesting to me. I know another guy that made some gen 1 style hammer & sear that is Teflon coated.he might be selling those on gb ??? That might help the trigger ???

I have that K&M Aerospace 4.5# spring sitting in a parts bin, waiting for a back ordered hammer pack for the last couple of months. I do not want to fudge my Gen 1 Pack!
I did send a spare FS2000 hammer pack to them; now the trigger pull breaks at 5#, but it will not pass a 12" drop test on the butt. The same will be true with the PS90, the heavier OEM spring helps prevent the hammer from releasing during an impact. I recommend only using these packs for bench shooting, and switching back to an OEM pack for all other purposes.

I really don't want to mess with the springs yet. On top of that everything I've seen is hit and miss.

Just day dreaming on this....

Ive been talking to my brother in law about using the cnc to cut out some ss trigger parts and see if I could add a beefed up safety so you can run a lighter spring. We're at the drawing board but have the tools to do it but need to make time to find out if we can make it work.

Do it, it won't hurt anything.

Polishing that is.

That is the catch right there, even when you have it in your hand and start the R&D / Troubleshooting it seems like the simplest thing gets really complex and or time consuming. It is one step forward then 2 or 3 backward ect... ect... then getting all the stars to line up to change things and end up with a viable product is a risk and very time consuming ! It always seems that no one wants to move at my pace and I resource help & expertise from several sources.
It's seems to be failure after failure until you decide what direction to go. Always keep in mind that the buying public is " frugal ".... the smallest chink in the products armor will be found. For lack of better words.....

I have done some reading but in no way can take my cumlitave knowledge on what I believe plagues this trigger design... and speak to it like 00stormbringer or SONYtec... they have just been around way longer in the game than my feeble mind. Hard to knock FN's design .... aka Browning's original trigger pack idea. It just works and pretty well, my issue is when I go from platform to platform the trigger pull just sucks comparred to Geisslle and other high end specialists... it is long and hard.... kind of what my wife expects out of me.... as long as I don't wake her up ! LOL......

Here is a pic of the Gen 1 Auto Sear & Hammer that I picked up. It is teflon coated, I would like to play around with installing this & " polishing " some components to at least smooth out the pull. If the 4.5 # spring is a safety issue that is out....
I would like to put something together,,,, I will say that it is probably not cheap, adding $100 bucks of components to the $75 trigger pack just to fine tune it but worth a try...

If anyone is interested in a set of these ? PM me, I believe they will be for sale or are on GB about $100-$115 ?

I would prolly get a set to try out. I posted up on Geisseles ar15.com sub form about the trigger. If they have something in the works.

I found a site that is called neu-trigger.com that I'm going to research.

There's nothing inherently wrong with FN's hammer pack designs. The PS and FS designs are safe and reliable with a service life of 90,000 live fire cycles.

Safety, durability, reliability and extensive live fire testing seem to take a back seat when it comes to making a buck off the average gun owner. These are the reasons why I chose the path I chose. Having thrown good money away on gimmicks and gadgets that failed to perform at the same level as OEM offerings.

If it's advertised as being "better", it should be better and not any less durable than what we currently have and let's keep in mind the PS90 & FS2000 aren't match grade weapons by design. Simply polishing the trigger bar and lightly coating the part with wheel bearing grease, coupled with applying a light mist of Rem Oil (Teflon added) to the hammer packs, which costs about $5 will do far more for a better trigger feel in these weapons than spending money on things that could potentially compromise the safety, reliability, and or durability of these weapons should be at the front of everyone's mind. Especially if they plan on handing a weapon to a loved one or friend.

My understanding is that this is the inherent issue with bullpup designs, you sacrifice a match grade trigger because of the design of a bullpup having the trigger in front of the trigger group. I would assume the AUG and tavor are the same as the ps90 and FS2k

I agree with you sgt, I don't want to use a spring kit cause of the safety issues I've (herd) about.

We'll I got off work early today and said wth I'm going to look over the trigger pack again. We'll I took it apart lol

i took some 1500 grit sand paper and cleaned up some rough spots on the hammer,sear,the block that catches the hammer. I'm not sure how much it is helping till I get something to measure the trigger pull.

The trigger pack for the PS90 appears to be a knock off of the AUG trigger pack.

Tavor is a little different, all the motion on the bars that trip the sear are pulling, not pushing. this take some felt slop out of the trigger as is next to no flex. I have one an you can feel the difference, Dave

I'm about to launch a 2-stage Tavor trigger pack, and it is good, though there is still a little slop in it, due to being a bullpup design that won't likely go away.

The FS-2000 both had the disadvantage that is is a 'push' design in the linkage, so there is a little extra sponginess, plus the parts are all plastic. They work allright, but they don't slide on each other nicely - there is a 'grabby' aspect to their friction.

I have not had time to dig deeply to come up with an alternative design, but I wonder if you made every second part out of metal, so you never get plastic/plastic sliding, if it would not make a difference.
