Yet another Powerline 880 trigger "mod"

[twigboy]

   I didn't want to hijack some other thread...
I didn't really want to heavily modify this rifle (the newer version ~2018 or so), but I like the modest results that I got.  It's definitely not going to be 2 or 3 lbs. but is lighter than stock (I had it measured at almost 6 lbs.).   I wanted to keep the gun as normal as possible but lighten the trigger some.  This meant I wanted to try to keep the flat spring in use.

I couldn't find the spring assortment kit at Home Depot (5 and 6 in stock but not on the shelves -- grrrr), but found one at Harbor Freight and another at Tractor Supply.  In the process of disassembly I fumbled the side covers in a spectacular fireworks display, where I watched parts spraying all over in slow motion like in a cartoon -- miraculously I recovered the safety ball bearing but no safety spring, huh?

Anyway, I found one spring in the TS kit (#1 assortment, Century Spring), installed it for the trigger/sear spring and tested.  It could dump 12 to 13 pumps of the factory valve without left overs.  But when assembling the stock found that it was too wide on one end.  So I took needle nose pliers to it to tighten up the wide end which then cleared the stock.  I kept the flat spring installed.

In the TS kit I found a small spring that fits the safety button, and cut it flush for a useful replacement.  In the HF kit I found a tension spring, cut it down to fit, and replaced the lever arm spring for a lighter clip.

I saved both stock springs (and will do the same for the safety spring if I come across it).

Take the flat spring out, throw it in the trash. It's only purpose is to keep you from pulling the trigger, with the bolt open. You'll be amazed at how much lightr your trigger is, without it.

I did recently cut about a coil off this spring and got it to about 3 1/2 pounds, about like I have for my hunting guns (deer).  And I checked that it can still dump 14 pumps, and doesn't release when bumping the gun hard.  I may do just a tad bit more because it can do 14 pumps (I stopped there), but for now I think I'm tired of the disassembly, mod, reassembly, test shoot, repeat process.

I know about removing the flat spring in reducing the felt pull, but when I did that there really wasn't much change.  The biggest reason for leaving it in is that the next person who shoots it may expect that is how it functions - they perhaps will read the manual so it still matches that way.  I really don't mind it.

It does somewhat bother me that the trigger face is a bit rounded, while most of firearm rifles are flat.  I may take a file to it or a trigger shoe (?).

Question:  What sort of grease should be on the parts?

[longhunter]

Any grease will suffice. Just don't use silicone grease. It causes galling on metal to metal surfaces. Moly grease is usually the best bet.
