Optic Milling For Glock Pistols
Description
Model: All Generation & Model Glock (43, 43X, 48 Is milled for 407K/507K, or RMRcc, only.)
Service: CNC Mill Slide For Optic (Optic MUST Be Sent With Slide - No Exceptions)
Finish: Cerakote Or Black Nitride
Other: We mill precision pockets for your optic! While many companies will mill an over sized "one size fits all" pocket, ours is precision as per your optic. The cycling of a pistol slide is not gentle. The last thing you want is all that force to simply be on the mounting screws due to an optic pocket milled too big! Screws have been known the shear and break over time due to improperly milled slides.
Configurations For Co Witness Sights Using Suppressor Height Sights:
Trijicon RMR & Holosun 507/508: Optic can be milled in front of rear dovetail or have rear dovetail milled out and mill new Glock dovetail in front of optic.
Deltapoint Pro: For lower 1/3 co witness, you MUST mill out the rear dovetail and mill new dovetail in front of optic. You MUST use plain black suppressor height sights.
If you are not worried about iron sights, any configuration is fine.

Top notch work, fast turnaround. Really could not be any happier with my order, will definitely use Primary Machine for future slide cuts.

Slide Milling
Ordered slide cut for my Holosun with Sniper Green Cerakote. Was expecting a gloss finish, but it is a flat finish. No problem as it looks great. Second surprise was that unlike my Glock 19 MOS which uses a transfer plate, the Primarymachine job has the sight sitting lower which is an added bonus! I can see my original iron sights, no need for new elevated sights. Also, seems to be far superior to the MOS as there isnt any slop, its a perfect fit. And lastly, the did the job over the holidays with no delay with a fast turn around So 4x Five Stars!

Glock 17/ Holosun 507C X2
Followed the mailing instructions and shipped my G 17 slide. I chose to strip the slide myself. I was periodically notified by Primary Machine as to the progress of the order. The slide was returned in about 3 weeks. Upon opening I noticed the machining was flawless. The slide came with the reflex sight attached. I reassembled the pistol without any problems and went to the range to sight it in. Holosun sights are factory pre zeroed, so if all machining is square, theoretically, little sight adjustment is necessary. At 10 yards the first 5 shots were to poa. At 25 yards group was 2” high (works for me) and at 50 yards again shot to the point of aim. The only sight adjustment was minor, 1moa up and 1moa right. So the sight is accurately placed on the slide, the machining, slide finish restoration and attention to detail are outstanding,
and pricing is reasonable. I was thinking to just get an aftermarket slide already milled for optics but for me, choosing Primary Machine worked out very well. I would unhesitatingly recommend their shop for those needing machine shop work on their pistols. -
Excellent Work
Had Mike do an RMR/407/507 cut on my Glock 41 with the intention to run a 509T with adapter plate. Cut came out great, 509T works exactly as intended, overall very happy with the work, process, and return time. Thanks!

this is the second Ive had done and love them both.
I've sent two slides to Primary Machine be milled so far. Both were back faster than the lead time. Packing was top notch and came with no blemishes that I could find. ABSOLUTELY Beautiful work couldn't be more impressed. I'll have third slide headed their way real soon. Great work!!!
