AR-15 Laser Engraving Jig: How It Works and Which One to Choose

If you engrave AR-15 receivers with a laser, the hard part usually isn't the artwork. It's getting the receiver in the same spot every time. A good jig takes care of that. This guide explains what an AR15 engraving jig does, how it works, and how to pick the right one from our lineup.

Jig only. Our jigs are not firearms and not firearm accessories. They are tools that hold your own receiver steady on the laser bed. They don't drill, mill, or modify anything.

What is an AR-15 laser engraving jig?

A laser engraving jig is a fixture that sits on your laser bed and holds a part in a known position. For AR-15 work, that part is a lower receiver, or a lower and an upper. Instead of guessing placement, shimming, or taping things down, you drop the receiver into the jig and the laser sees it in the same place every time.

Why use one?

Repeatable placement. The second receiver lines up like the first, so your artwork lands in the same place.
Less setup time. You aren't rebuilding a setup for every piece.
Both sides without starting over. Our lower jig lets you engrave both sides of the lower without repositioning or readjusting it.
Anchored to the bed. The jigs use 6.5mm holes as an anchoring system for fast, repeatable alignment.

How it works

Anchor the jig to your laser bed using its 6.5mm holes.
Set your receiver into the jig. The jigs are modeled around a stripped Anderson lower and upper, and are made for standard mil-spec AR-15 receivers.
Run your engraving file.
Remove the receiver, drop the next one in, and run it again. It sits in the same place.

The jigs are 3D manufactured, built to last, and colors may vary.

Which jig do you need?

Gen4 Lower & Upper 2-Piece Set (Standard)

This is our main jig. It holds the lower and the upper, and the Gen4 version adds anchor points for the dust cover and the pic rail. It's made for standard mil-spec AR-15 receivers and will not fit 80% lowers. For those, see the 80% jig below.

See the AR-15 Lower & Upper Gen4 2-Piece Set

Gen4 80% Lower & Upper 2-Piece Set

The 80% Gen4 jig is for operators who need to engrave 80% lowers before drilling out the fire-control group cavity, leaving the trigger, hammer, and safety selector holes undrilled. We also supply a pin that makes it compatible with the regular mil-spec lower. In other words, if you plan to engrave 80% lowers and standard lowers, this is the jig you want.

xTool F1 Ultra Jig

This version is made for the xTool F1 Ultra, with a 70mm on-center bolt pattern. Check your Ultra's pattern first, because some vary. It includes right-side and left-side receiver jigs, a charging handle piece, a dust cover piece, and upright top receiver pieces.

See the AR-15 Jig for xTool F1 Ultra

AR-15 Lower Jig (single lower)

If you only engrave lowers, this is the simpler option. It's modeled after a stripped Anderson lower and is compatible with most standard mil-spec AR-15 lowers.

What's not included

The receivers, the dust cover, and the charging handle are not included with any of the jigs. You supply your own parts.

Frequently asked questions

Do I need a specific laser?

The F1 Ultra version is made for the xTool F1 Ultra's bolt pattern. For other lasers, check the mounting pattern against the jig's anchor holes before you order. If you're unsure, message us before buying.

Is the jig a firearm part?

No. It holds your receiver during engraving. It isn't a firearm or a firearm accessory.

Can I get the files and make it myself?

Yes. We offer digital STL jig files on Printables, Cults3D, and Patreon. The ready-to-use physical jigs are on our own website and ship directly from us.

How fast do the physical jigs ship?

Orders typically ship within 1–2 days and arrive in about 5–7 days. See our shipping and returns page for details.
