Maintaining USGI Trigger

[ridgerunner70]

Is there a good thread on DIY proper lubing,spring replacement, maintenance ,etc. on the USGI Trigger? I've done a search and there's several but goes off topic or just throw in an aftermarket brand,etc. Sorry if I've missed this.

Never maintained it. As long as it isn't rusting, whatever lube trinkles down to it is what it gets.

I wouldn't worry about it as long as it isn't full of sand. Lube from the BCG should be plenty if you've done it right. Nothing beats the feel of a shitty but comfortable USGI trigger pull.

God how I love them.

I know I like the stock trigger on my LE6920. Not too heavy and it has a very short reset and no takeup.

I got a DDM4V1 and the stock trigger came with it. I took the trigger out and dabbed grease at the contact points. I have 1000 dry fires and 400rds through it. Would this trigger be considered broke in?? Could I touch the contact points with a piece of sandpaper to smooth out a bit? When I pull the trigger it has one spot it gets tight, like a little click then pull a little more and a clean break.

That sounds like a dead-perfect USGI trigger to me. :confused:

Ok that's great!! I don't know much about triggers and was just wondering if that what I'm looking for in the trigger. Thanks!!

I would have to assume nkilo is being a little sarcastic; usgi triggers are notorious for being rough and heavy yet 100% reliable. You want smooth crisp and lighter, then go aftermarket; don't "sandpaper" the one you have, as you can easily break through the thin casehardened surface and trash it pretty quick.

I haven't had to do any real maintenance on mine, other than making sure it's not collecting too much crap. I did have to remove my FCG, safety, and grip last night to chase out a blown primer, so I went ahead and cleaned everything really good with CLP before reassembling it.

I've got an A2 that has been around the block for a couple of decades. I've replaced gas rings, buffer springs, and extractor/springs, but never felt the need to replace the hammer nor trigger springs, the FCG has worked without a hitch. I'm sure those parts can wear out, but so far their lifespans seem to be pretty long.

I just hit mine with a little bit of lube and make sure there isn't a bunch of shit in the area when cleaning. Other than that, I don't mess with them. Love Colt triggers.
