Trigger sear: stone recommendation?

Brians356

Gold $$ Contributor
If I want to simply clean up the sear on a R-700 (or 40x) trigger, what would be the stone to buy from Brownells? Anything else I need? Don't want to buy hundreds of $$ worth of tools, but Brownells has a free shipping on all orders, today only, and I have been wanting to get a stone etc. for simple smoothing of sears. I'm looking at their stone / lap etc tools, don't know what is best for my needs.

Quick responses appreciated!

PS I found this thread elsewhere, I'm beginning to think there's more to this than I assumed. I'm good with tools and careful, but not sure I could know when a sear plane is "right" even with the right lap tools.

I use the square white and red stones from Brownells. Damned if I know the # but they are like 1/2" square and 6" long. Look in the 1911 tooling. That's what they are made for.

I find 1911"Trigger Track Stone" or "Hammer Slot Stone" but they are all gray.

There is a two-stone set (black and white) just listed as 6" X 1/2" X 1/2" Ceramic Stones ("fine" and "x-fine" grades) for $49.

The only red stone I find are 4-inch "Gesswein Ruby Stone" in different shapes.
 
I have a Lansky knife stone kit with a wide assortment of stones, six I think. Cost around $40. Useful for many jobs, not so much for knives.
 
Must I have a fixture to true up a R-700 / 40x sear?

I found this post over on SniperForums from 2008:

Well, this is somewhat random, but related. I just finished stoning, then polishing the bearing surfaces on my stock Remington 700 trigger.

Not much stoning was required really, I started with 14 Micron Silicon carbide/Carborundum lubricated with Kroil to smooth up factory mill marks and flatten the faces; you end up with a frosty, but very flat surface.

Polishing then began with my white Lansky ceramic stone (also 1000 grit, but results in polishing not frosting on the already-flat surface) lubricated with Nathan's honing oil, which resulted in a brilliant finish.

BUT...I am obsessive over some things with rifles, and triggers are one. SO, I proceeded to polish the bearing surfaces yet again, but with 1.3 Micron Cerium Oxide (had it lying around for stone lapping and polishing). Now, you talk about a polished surface! They're little mirrors now, and smoother than any baby's bottom ever thought about. Oughta prove to be a much better trigger now, at 3 lbs and no creep.
 
I just found this thread from this forum (2012) and is makes this sound like a fool's errand, not for "learning on the job", so to say:

I've got the same...don't remember the last time I used them on a knife.
 
You can get a slew of different grit and shape abrasive stones and bones from enco.

If youre asking about which stone and which fixture i wouldnt recommend you stoning a sear. It shouldnt be done anyway. To have a safe trigger you should double down your money and buy a replacement like a timney or rifle basix
 
My suggestion is if you have not done this before, find someone who knows cocking piece sear, timing. without the proper set up you can screw one up in a jiffy.

What Nat said , but I used my dremmel tool with the polishing wheel and some compound on my AR trigger for a smoother engagement......for my Remingtons I would just get a Jewel an be done .
 
Thanks for the comments all. I think I'll take it to a gunsmith rather than do anything myself. It's a practically new XR-100 with 40x style trigger. Not wanting an extra light pull, it creeps a little which bothers me.

^^^ what he said.
 
I use a Arkansas fine stone(orange reddish color) to shape or take material off. Then a white ultra fine fine stone to smooth. The ultra fine stone is what really makes a nice trigger for a remington. I only use the orange stone every once in a while. The white stone is what I use mainly, it will leave a great creep free pull. If you know how and what your doing. Just stoning the contacts of the sear and trigger is only half the battle. If you want more info P.M me
