Optic Milling Options

We offer optic milling options for several optics. Here are the details listed below of each.

Trijicon RMR - Indexing posts are used to keep the optic zeroed if removed for battery change or to be used on another platform. We set our cowitness sight picture for lower 1/3. This gives more thread engagement to hold the optic onto the slide, and it allows you to see more of the optic window.

Romeo 1 - Mount your Romeo 1 optic to our slide. Hardware used is a more conventional 6-32 socket cap and will be supplied.

Romeo 1 Pro - Mount the Romeo 1 Pro onto your slide. This is not compatible with the Romeo 1. The threads for the Romeo 1 Pro are 4mm. These do not fit into the standard Romeo 1 chassis. 

Delta Point Pro - Now added to our options is milling for the Leupold Delta Point Pro. Four indexing posts are used specifically to the delta point pro. This optic is very tall. Co-witnessing is achieved by using the Delta Point Pro rear iron sight and a Dawson precision .455" tall front sight, Part # 021-543. This cut removes the rear dovetail to make use of the proprietary rear sight from Leupold. 

Vortex Viper - Indexing posts are used to keep the optics zero when battery changes are needed. Lower 1/3 co-witness with suppressor height sights.

Vortex Venom - Indexing posts are used to keep the optics zero if removed. The optic is much larger. Sig suppressor sights don't work as they protrude forward into the optic when installed. Recommend using a sight style like Trijicon suppressor sights.


Finishing options are unfinished, black, and Battle Hardened.

Unfinished - slide will come uncoated. Before shipping we'll media blast the slide. From there you can cerakote or finish the slide as you want. Since we don't have to send out for coating, these slides will ship much faster.

Black - Slide will arrive black.

Battle Hardened - Battle hardening is distressed black. The black slide will be distressed highlighting the edges giving the slide instant character.  


  •  Optional optic milling configurations
  •  Pick the preferred slide design you want
  •  Slide is stripped without any internals, sights, barrels, or moving parts. Channel liner will be installed

The staff is awesome and very easy to work with. They are knowledgeable about their craft. The quality of their product is off the chain and I highly recommended this company and their products. I will be purchasing from them again.

P320 compact slide with Bentham cut

The finish is beautiful. I installed Sig internals and barrel. I broke it in with 400 rounds of 124gr ball and it shot great. No malfunctions and at 15 yards it kept a sub 3in group. The RMR cut is very precise. I love the P320 and always wanted to mount a Trijicon RMR to one. This slide is awesome. I would highly recommend any Norsso slide.

Bentham Sig 320 compact slide

This is a very well made slide. I haven’t shot it for accuracy so far but it seems to do well. Mine has an RMR cut. The RMR cut is so precise that the RMR has no movement even without the screws installed. I don’t have the sights I bought to install yet but I’m sure they will go on with little issue considering how precise the rmr cut is. Their machine cut would take several extra steps over what most shops do to machine an RMR slot. Very happy with my purchase.
