Description
The Spikes Tactical SED7007 is a mil-spec ejection port door built for right-hand-ejection AR-15 upper receivers. It's stamped from steel and wears a heavy phosphate coating in black, so it holds up against dirt, moisture, and the general abuse an AR sees while keeping that low-reflective look most builders are after. Where it stands apart from a run-of-the-mill dust cover is the laser-engraved 'Zombie Killer' marking tucked on the inside face.
What Makes the Zombie Killer Door Different
The engraving stays hidden when the door is snapped shut, so from the outside your rifle keeps a clean, all-business profile. Flip it open and the 'Zombie Killer' script shows itself. It's a small detail, but it's the kind of thing that separates your build from every other flat-black rifle at the range without touching function, reliability, or fit. The laser work is crisp and sits below the surface, so it isn't going to rub off with use.
Fitting the SED7007 to Your Upper
This is a standard AR-15 dust cover, meaning it drops into any mil-spec upper receiver using a hinge pin, torsion spring, and C-clip. If you're building an upper from scratch, plan to install it before the barrel and handguard go on, since the assembly seats from inside the receiver. The little C-clip is the fiddly part of the job, so a well-lit bench and a pair of needle-nose pliers make it a lot smoother. Once it's in, a quick function check should have the door snapping open and closed under solid spring tension.
A Simple Way to Personalize Your Build
For anyone chasing a themed build or just wanting to add some character on a budget, this is about the easiest upgrade going. It's made in the USA and backed by the Spikes Tactical lifetime warranty, so you're getting a genuine mil-spec part that trades zero performance for a bit of personality.

Frequently Asked Questions
Does the SED7007 come with the hinge pin, spring, and C-clip?
No, this listing is for the ejection port door cover only and does not include any additional hardware. You'll need a hinge pin, torsion spring, and C-clip to install it if your upper doesn't already have them. Most builders reuse the hardware from their existing dust cover or grab an inexpensive install kit.
Will the Zombie Killer door fit any AR-15 upper?
Yes, it's a mil-spec part designed for standard right-hand-ejection AR-15 upper receivers. If your upper is mil-spec, this door will fit the same as any factory dust cover. Just make sure you're not trying to fit it to an AR-10 or left-hand-eject upper.
Is the Zombie Killer engraving visible when the port is closed?
No, the laser engraving sits on the inside face of the door, so it stays hidden when the cover is snapped shut. Flip it open and the 'Zombie Killer' marking shows itself. It keeps your rifle looking clean from the outside while adding a bit of flair when the door is open.
Is this door tricky to install?
The door itself is straightforward, but the small C-clip that retains the hinge pin is the fiddly part of the job and easy to launch across the room. Work in good light with needle-nose pliers, and plan to install it before the barrel and handguard on a fresh build since the assembly seats from inside the receiver. Once it's in, a quick function check should have it snapping open and closed under spring tension.
