How important is it not to have a oil hole?

**Lawdog-1** · 11-13-07, 21:28

I just noticed some difference about two LMT lowers that I bought after the Ban was over that these 2- LMT lowers don't have a oil hole on the side of the Rec at the front pivot pin spring. Do I need to add a hole on the side of the lower Rec to oil the spring at the front pivot pin?

I've never had a problem not having them there. No biggie on this side.

It's better to have it, but I've managed to get by for a decade or so with a few Colt's that don't have them (Early small-pin lowers that I drilled out for push-pin detents).
If you were operating in extreme conditions (lots of mud, sand, dust, slime spewing zombies...) it would be more of an issue. Most of us aren't doing that so it's less of an issue.

I've always wondered if it was actually for oil..........or............is it to allow water to flow through it after submersion in water.

I think it's probably for both.
Neither of the Colt Armorer's manuals address it (that I could find anyway). In fact, they don't even show the weep hole in the diagrams.

It's called a weep hole, designed for whatever is in there to work it's way out-hopefully. The ejector has one as well, that's why in cleaning you're supposed to place a drop or two of (your brand) on the ejector while the bolt face is facing up and depress the ejector a few times.
