Sig P320 Optic Milling
Model: Sig p320
Service: CNC Mill Slide For Optic (Optic MUST Be Sent With Slide - No Exceptions)
Finish: Cerakote Or Black Nitride
Notes: We Do NOT MILL For Romeo Optics & We Will NOT Mill Slides Which Have Been Milled From Sig
Sight/Co Witness Notes: Our Sights Will ONLY Work With Trijicon RMR & Vortex Viper
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.
Absolutely perfect job. Hard to believe but no zeroing required. I didn't even send the barrel but it shoots point of aim at 25 feet. Tight fit of RMR to slide and proper recoil lugs milled in. Iron sights co-witness perfectly. Will definitely have more done.
Top of line
Unbelievable quality and service. I seldom write reviews but was very impressed with the optic milling and cerakote performed by Primary Machine. The optic fits very tightly. I also wanted to share the excellent customer service and how quick they turned around my order. Very impressed and will continue to send them my business.
Very happy with slide and optic. Fast turnabout. Placed a 100 rounds through it and was flawless. Plan to send a Glock now!!
The workmanship looks great and I shot 150 rounds through it this weekend. Functions well. Even zeroed in when I got it.
Hello all , I have sent in a sig p320 slide to be milled for a rmr opticand re-finishing in magpull fde which surprisingly matched almost perfectly with the fde plastic grip & alsoeven better on the optic it self. The milling job was well done and vary tight fit which is great for carry pistols. Also the co-witnes sights line up good and doesn’t take up much space in the optic window as I was plesantly surprised about an all around good job in all. The only con i thought could be inproved would be the contact system , i tried to call multable times in the limited hour’s thay provide for calling but I had no such luck but there is an option to leave a voise-mail. I was however able to contact them on the facebook mesage on there page and responded to the questions quickly and clearly with all my conserns. There work is vary good and I would recomend them if your on the fence.
Awesome job on my Sig P320 project! It earned you 2 more slide milling and coating jobs-keep up the great work!
What amazes me is the quality and fast turn around of Primary Machines work. One week! Would recommend highly and would send other slides in the future for work
Perfect milling for my RMR. Great Paint Job.
The only reason I am not giving a 5 star is because they do not sell milling caps to cover the milled area on the slide for SIGs.
*About the only thing you will MAY, not need, want to do after milling, is buy a battery plate to cover a small milling.
