Lead times may vary based on current workload or current governmental restrictions.

Normal lead times are approximately   6-10 weeks for slide work and refinishing in BLACK NITRIDE

Refinishing in FDE PVD may be longer than normal 6-10 week (slide and refinishing) lead times. 

Slide milling 1911 for the Trijicon mount or RMRcc may fall outside of normal lead times.

Custom slide work or work requiring new programming will fall outside of normal lead times.

Slide milling for the  RMRcc, the screws and seal plate provided by Trijicon must be included with the RMRcc optic if you want the optic mounted on the slide by ATEi.

Slide milling for optic install on Glock 17L, 24, 41, Sig P320 (full size), Beretta APX or other slides with a void where a plug and laser welded are needed are not subject to normal lead time due to additional processes involved and will incur an added cost for the additional services needed.   Slide milling may not be offered for slides not already listed. 

We do not offer slide milling for any of the HK P30 models at this time.

If you send a Lone Wolf  AlphaWolf slide for milling, make sure it is NOT the Featureless Slide.  The Featureless slide is not like the AlphaWolf   Replacement Slide. See picture below for reference.

You want the AlphaWolf OEM Serration Slides (AW-Slide-OEM).

ATEi installs only Trijicon seal plates under a Trijicon RMR.

Slides altered by anyone other than ATEi may not be modified by ATEi.  Please contact us for confirmation your modified slide can be machined by ATEi before sending it in.

Shipping costs are a separate charge and a phone call to us with your credit card information is needed. 

We ship using UPS and an ADULT signature is required. 

The customer is responsible for shipping costs to and from ATEi.  

If you are purchasing an Accessory (such as batteries, sights, an Apex barrel or Trijicon seal plate), it is assumed that you will be sending in your slide or pistol for installation.  COST FOR ACCESSORY ITEMS DOES NOT INCLUDE  SHIPPING CHARGES.  If you are ordering an Accessory as a stand alone item, call us to pay for shipping! 


Nickel Boron Refinishing is no longer available for Slides or Barrels.  

 Any changes to orders after being placed must be made by email to info@ateiguns.com.

ATEi does not sight in firearms. 
Final adjustments of both iron sights and optics are the responsibility of the end user.

  Effective March 5th, 2018 ATEi will no longer accept packages shipped through FedEx, nor will we return items using customer supplied FedEx labels, until further notice.  We apologize for any inconvenience this may cause.  We feel strongly in our stance against FedEx, but more importantly in our Second Amendment Rights and cannot support a company who has publicly stated an opinion that undermines, infringes upon or would like to limit our Second Amendment rights.

If shipping a Firearm, you’ll need to ship directly to us using UPS ONLY, per Federal firearm shipping regulations. Firearms must be return shipped NEXT DAY AIR or shipped to an FFL. You may also have your local FFL ship Firearms to us using USPS. If only shipping anything else (slide, barrel, small parts, anything other than the serialized frame) you MAY ship any way you wish (USPS, UPS ground etc).

NOTE: We have had several customers use USPS only to have their stuff lost in the mail.  Therefor we do not suggest using USPS to ship ANYTHING.  We haven’t had these issues when customers use UPS.  Always obtain tracking and insure your shipment for full value.  Packages coming back from ATEi will require an ADULT signature.
