Reducing pin hole in AM/MM sear to work in RTPro?

[OneSelfLost]

Hey everyone,

All these AM/MM sears in my kit and all I need is an RTP sear.. Typical!! Haha

Does anyone know the ID and OD of the reducers? Think they'd be easy enough to make? I'd rather save a few bucks and not buy a new sear if I can avoid it.

Thank you,

Bushing! That's the word I'm looking for!

You are going to have a tough time drilling that sear. They are VERY hard. The bushing is not available. You will go through 50 dollars worth of aggravation for a 30 dollar sear...

What Tuna said but the measurements on the RTP bushing is: OD 0.25" ID 0.125

I'm not planning on drilling anything, just finding a bushing. However, you're probably right.. I'll shoot you an email soon, Tuna.

Thanks guys!

You can't just put a RTP bushing in a Automag sear, the AM sear pin is .187". You might be able to turn one to fit on a lathe but the side walls would be fairly thin. (0.31")

Ahh okay! Definitely more work than its worth then! Thanks Luke!

Yes, thanks. :)

I've wondered how that would come out also. In brass, that thin wall would not press fit well, making it either loose or glued-in.

I believe the bushings are bronze...not brass.

sell an extra am/mm sear to help offset the cost of an rtp sear and axle.

The two sears have slightly different geometry even if you fill in the hole. Refer to the CAD files.

What? More "science"? aaagggh!
