Need replacement RMR screws: factory or aftermarket?

[awp_101]

Long story but I had to drill out one of the factory RMR screws on my M&P CORE. I was surprised to find neither Brownells nor Midway sell replacements. Or if they do, they’re well hidden but that’s not important right now.

Should I just contact Leupold for replacements or pop for some of the $6/ea from one of the aftermarket vendors? I’ve seen threads about buying a box from McMaster-Carr but I’m just maintaining a fleet of one currently with the outside chance of a couple others later on down the road.

If you have to buy three or four screws, that box of 100 plus freight will come out to less.

I got a box of 100 from the local Ace Hardware. Was surprised they had what I needed.

Hmmm, there’s an Ace on my way home and I need to stop in one day this week anyway. If they don’t have any, Fastenal/Mc-C here I come! Thanks!

Odds are, if you need to replace one screw, you will need to replace more. I would go the the McMaster thread and get a whole box of the right screws with the Torx head, as they cost about the same as two screws from Trijicon. I would also get some Fix it Sticks, and proper bits.

So that’s what kicked this shit show off to begin with.

I threw a Fat Wrench in my cart on a Brownell’s/Midway/Amazon order one day. When it came in The Good Idea Fairy thought it would be prudent to remount the screws on my CORE. I set it to 15 in/lb (IIRC) just to get a feel for how it works and the cheap bit it came with twisted right off in the screw head.

I put it off to the side and just shot it at the range occasionally thinking/hoping the broken tip would just work itself out. Obviously that didn’t happen so I just let it ride until a couple of weeks ago when the battery finally died. My first attempt with a tiny drill bit didn’t do any good trying to get just the broken tip out so I just had to trash the whole screw.

Hey, at least you got the screw out yourself!

It was touch and go for a couple of days until I realized the non-marring jaws on my vise also fit the small machinist-style vise on my drill press. Much better, faster and less nerve wracking than the cordless drills I have. :D

With a buggered screw, I have had good luck pounding a Torx bit in and having enough bite to back the screw out.

Please post the screw size you need. I’ve placed a few mcmaster orders…

Their website is a bit of a Gordian knot, but worth the effort for the quality you get.

I haven’t actually looked up the actual specs yet. It’s end of month at work and the normal madness during the rest of the month grows by an order of magnitude. I do know it’s the factory screws.

With McMaster, you know exactly what strength and alloy you’re getting. Local hardware stores, often, not so much.

No problem, thanks for checking!
