What are currently the best* outfits for getting a third generation Glock slide milled for a red dot sight?
*Sufficient consistency, low price, fast turnaround.
I used Battlewerx a few months back for a mill and refinish. It was just over six weeks from them receiving it to it shipping back out, though apparently the refinish is the lion’s share of that and if you don’t need/want that it cuts it to two weeks or so. $100 for the milling, $60 for the refinishing.
The milling was top notch, very cleanly done and the RMR fit so tightly as to need some wiggling to get it firmly seated.
ATEi (https://ateiguns.com/) and C&H Precision (https://chpws.com/)
ATEi is the gold standard. Dougwg is a member here. His work is good enough for one of my guns to hold zero with only one mounting screw for 500ish rounds in a class.

Yeah you should check out the chpws thread on snipershide before you recommend them.
Have you used them personally before?
Yes, they just did a 43x slide for me that is as good of work as the guns I have had done by ATEi. They have also done a 19 for me in the past. Turn around was fast. I had no issues or has any of my friends that have used them.
Jagerwerks.
Had a Gen4 G19 milled….very happy with quality/price/time. Would use them again.
RMR cut, front and rear enhanced serrations, cerakote.
Been thrilled with Monsoon Tactical in terms of quality and lead time (3-5 weeks). Have the chunk port done while it’s in there, all the benefits of a comp but not finicky with ammo and no length added.
Another recommendation for Jagerwerks here. He did a CZ for me and cerakoted at the same time. Clean work, reasonably priced imo and completed in the time quoted. Can’t ask for more.
C&H
ATEi
Maple Leaf
Jagerwerks
Battlewerx
Continuous Precision
There are honestly more quality outfits than I can keep track of. I have been using Maple Leaf lately as their 2 week turnaround is good and their LE/MIL discount is great.
Bumping this thread as I’m looking to have a Glock 17 slide cut for a red dot. Anyone have any new companies to add to the list? The top two look to be ATEi and Jagerwerks so far.
I will again put my vote in for non milling and getting a Leupold Delta micro instead. I am now trying to find a machinist to mill me a mount for the dove tail on my CZ P10f comp so I can put a Delta micro on it
Gave a hard look at the Delta Micro and I like it. I think I’m gonna try one on my Glock 43x. But the slide I’m having milled is for duty use in a Safariland holster where the Micro would be incompatible. It’s gonna be for an Acro.
I just got 2 slides back from DP Custom Works. Flawless work with an excellent price. He offers a 20% first responder discount. I also believe he offers a 10% discount if you sign up for his newsletter.
They do quality work for sure
Had a Glock slide milled by Wager Machine, had it back 5 days after they received it; I was happy with the work.

Who did you end up having cut your slide for the Acro? Any feedback?
Same company for my g19.5, they even installed ever thing I sent them, no idea what freaking loktite they used because I cant get rmr off to replace the battery.
Lotsa good info here !
