The Extar EP9 (check out the review HERE) is a fun little personal defense weapon (PDW) chambered in 9mm Luger. With a pistol this fun to shoot, you’re going to have to clean it often. Here’s how you take the thing apart!
Extar EP9 Upper and Lower Separation
Disassembly is accomplished by first ensuring that the weapon is clear (no magazine inserted and no round in the chamber), and then pushing out the rear takedown pin located in the same spot as on an AR.
Next, you place your non-dominant hand in a sort of firing grip on the magazine well, then use your thumb to push FORWARD on the handguard. The front of the upper receiver is NOT held in by a pin like the AR-15’s- instead of going through a hole in a tab on the receiver, the pin stays in place and the receiver has a hook that holds it fast to the lower.
Extar EP 9 Bolt Removal
Once you have the upper and lower separated, you can draw back on the charging handle and remove the bolt through the rear of the upper receiver.
If you want to take the bolt apart, all you do is tug rearward on the back half- this is a weight added to give the bolt mass. After it comes apart you can then see the firing pin. To remove the firing pin you must first take out the cotter key on the left of the bolt (as you’re looking at the pin), then the bolt will come free.
Extar EP9 Buffer Removal
Instead of a plunger to retain the buffer spring, there is a plate located just in front of the buffer, which has a small tab that protrudes up in place of the plunger. To remove the buffer simply push in on it to relieve the pressure and pull the plate “up” and out.
In order to reassemble the weapon you reverse the process. Check out my video on the Extar EP9 disassembly/reassembly process for more details, and to see how to remove the handguard and muzzle device.
