That's some good work on the measurement estimates.  I'm very interested to see the reduction with the spring kit.

If plastic needs to be shined up inside, I used this stuff in the past working on Star Wars props.

Well cleaned everything, did a little polishing, put it all back together and tried the pull and there was maybe .5-1lbs less. Ordered spring kit so we'll see if that does the trick. Also it did have a trigger set screw. Just had to break it loose. Going to take up what slack I can.

I just put this spring kit in my 500 tactical. Dropped the pull a couple lbs. Makes it a bit easier to pump, but I don't consider the 500 a smooth action anyway.

Got another question. What compound would I use to buff and polish all the trigger parts?

People seem to like Flitz and I've used it in the past. I just did my Mossberg trigger yesterday, and I didn't really see obvious areas of improvement.

So you got a Mcarbo spring kit and it didn't improve the trigger pull? Well they say they have 100% money back guarantee so I'll try it and if it doesn't improve the pull I'll send it back. I just don't know what else to do except live with it.

Sorry, let me clarify. The Mcarbo spring kit improves the trigger pull by lightning the hammer spring and trigger return spring. This is worthwhile IMO.

What I was referring to is further polishing and buffing of the Mossberg trigger assembly and it's parts would probably be a waste of time.  It will be mechanically light at around 4 lbs after the spring kit and break clean so the inefficiency of the bullpup trigger linkage will be the problem.

Oh ok. Well I know there's some issues with the bullpup linkage. Not sure if there's anything that can be done with that. The trigger pull weight is the biggest problem, way too heavy. if you don't let the bullpup trigger go all the way forward, just until it clicks, the follow up shops are quicker and easier.

FYI- I found my Wheeler trigger gauge. The Mossberg 500 with the Mcarbo kit is 4.5# with some take-up and a crisp break.

My 870P is 4.5# as well.

Well all I have is some cheap fish scale to check the pull BUT it did allow me to compare the difference pulls.

Well I switched out the original trigger springs in my Mossberg 500 for the M*Corbo springs. Rechecked the trigger pull with the fish scale and to be honest only saw maybe a 2lbs difference even though it's does feel lighter to me. Going to take my bullpup to a gun shop tomorrow and have them check the trigger pull with an actual trigger pull gauge. I thought about sending the spring kit back BUT I lost (dumb me) the original trigger spring but it's all good.

Maybe time to ask if it's worth going forward with it after the gunsmith looks it over. I have the Mossberg factory bullpup and I live with the heavy trigger as a byproduct of it's compactness (plus it's super cool and collectible). I don't expect much of anything good coming from a metal rod running from a fake trigger to the real trigger.  The Mcarbo is doing what it's supposed to do and if you put it back to stock, you'll have a nice 4.5# pull- same as a 870.  Have you tried the KSG?

Well although the KSG is nice it was 3 times what I paid for the Conversion kit since I already had the 500. All I'm going to do at the gun shop is just have them check the trigger pull weight. I realize that the rod from a fake trigger to a real one isn't ideal but it does work.

Ok. Well had the trigger pull checked and it broke at 8.5lbs in the bullpup. That works for me
