I've had good luck with PTG. Some people diss them pretty bad, but I've never had an issue.

Does it have to be a mini?
I've installed some of these:
I like them; they come with detailed instructions.

You're right.
LRI AR-15/M-16 Extractor for Remington M700 style bolts
Machined entirely in house the LRI version of the Magnum AR15/M16 extractor offers a more reliable alternative to the OEM Remington type. Our extractors begin as bars of 4140 Chromoly and are in a parkerized finish. Springs are made from a slightly heavier wire gauge to increase shell pressure...

Do you happen to know if PTG supplies a drawing to make the cut?
With all due respect, do not use the PTG instructions, as you will cut away quite a bit of the bolt lug if you make the cut at 45 degrees. NOT GOOD! Their instructions do not mention a .223 case head either. Get your dimensions from an already functioning bolt as this cut is quite deep and it's easy to ruin a bolt. My personal choice of Mini M16 extractors is the one made by Defiance Machine. A nice little unit and great people to deal with.

The LRI print looks to have the correct dimensions after checking it out. I have not used their print in the real world, so proceed with caution. I always make up a dummy bolt head in aluminum to work out any bugs before cutting a real bolt. The LRI print is correct with the 36 deg angle as well. The same angle I use as well. Good luck and keep us posted.

I deleted the post - shoulda looked closer at it. Why am I not surprised it's got bad information?
All good my friend. The 45 degree angle was their solution to cases ejecting to high from the extractor and hitting the windage turrets on the scope. Oh sure, lets CUT half of the locking lug away to lower the ejection angle!! What could possibly go wrong!! You just cannot make this stuff up.I deleted the post - shoulda looked closer at it.

The biggest key to installing the m16 style extractor, is a way to precisely rotate the bolt 90 degrees to drill the pin hole. Figure that out before you start cutting anything.
My 4th axis on my mill will rotate to 3 decimal places. Close enough! Lol. Walt is correct, as it is absolutely critical that is exactly 90 degrees. More or less, and it will not function correctly.

I've not installed one but it seems to be SOP with a rotary table on a manual mill..similar to the pin on an aftermarket bolt stop.
Am I missing something?
The bolt handle gets in the way on a lot of rotaries. I use a V block, but have to figure a way to dodge the handle.
