Review: DyTac Invader Mag
Dave Miller

Review Overview

Compatibility with different STANAG based AEGs
Long term reliability

A good budget midcap

For the money this is an excellent piece of kit. It looks good, feeds in a variety of weapons, however the spring does wear down with a bit of use.

Item Name: DyTac Invader 120rd Mid-Cap Magazine
Item Type: AEG Midcap Magazine
Cost: $8, $36.48 for a pack of 5

Preface: I have been using this magazine for a good five months now, and the main spring has weakened a fair bit. The mag struggles to feed the last 20 rounds or so, resulting in me dropping the score slightly.

This was originally posted on my blog – Loads of Balls Airsoft, but I’m moving over to writing for AO as I prefer being part of a team!

I had heard of DyTac a few times during long crawls through the bowels of various hong kong based retailers, but it wasn’t until I was seriously searching for a free float rail system that they grabbed my attention (but that is a review for another day).

When I saw that they manufactured polymer magazines that were significantly cheaper than Pmags I just couldn’t resist picking one up to see how it performed. After all, tagging eight dollars onto an order wasn’t going to break the bank.

When the magazine turned up it arrived in foil packaging (this was at the back end of january), which did the trick. So long as the stuff I order arrives intact I’m not too fussed by what contains it.


The packaged mag

Removing the mag from the packaging revealed a sleek simple magazine with checkering on the lower half for easy grip. The word DYTAC is emblazoned on the side of the mag at the base.

The design borrows heavily from Magpul’s Pmag, but looks different enough to satisfy those who want cheap polymer magazines without going over the top on the Magpul front (such as myself).

OLYMPUS DIGITAL CAMERAMould lines were evident on the front and back of the magazine, with a rather noticeable gate on the front side of it. The magazine accepts magpuls, which do look good in the same colour, and they are securely fitted to the magazine.


The mould line & gate

Having oooh’d and aaah’d, it was time to see whether this was $8 well spent or wasted. The mag filled up smoothly, taking 31 presses from a standard speedloader, or 123 rounds. It fitted (with some play once fitted, but no risk of detaching) and successfully fed in my old M4gery, featuring a G&G Lower/innards and a JG upper.

As you would expect it fits and feeds beautifully in my DyTac M4, and it fits and feeds smoothly in an ICS M4.

The Floorplate

The Floorplate

The one issue I noted is that while the mag is retained in the ICS M4, a wiggle and sharp tug would remove the magazine from the gun. In all cases pressing the magazine catch would cause the mag to drop free from the gun, to satisfy the Travis Haley speed reloader within. It also fits and feeds in an SRC based M4gery that a mate owns.

It also happens to fit nicely in an Ares TAR-21, but (as with 90% of mags that I’ve tried) refuses to feed reliably.

The mag (when shot empty) will leave 1-3 rounds stuck in the mag in addition to the four you lose when unloading, this is hardly a great detriment but could cause an issue when checking to see if you have drawn a loaded mag from your rig, and it is at times like this that one must resort to a method of indicating whether a mag has been used or not.


After maybe 10 loads/unloads I noticed wear to the bb retaining catch. This is due to it not being able to withdraw far enough from the tube due to its design, resulting in the hop unit nozzle mashing the lip of the catch. This has not worsened in any way, and the magazine still retains rounds quite happily. (After four months use dropping a loaded mag from waist height onto concrete results in a few rounds escaping the mag).

Dissassembly is easy, all you need to do is remove the screw at the bottom, push the black plastic plunger and slide the baseplate off. Then drive the pin out of the body near the top, and pull the innards out. The standard “remove screws till the spring explodes everywhere” approach is successful in taking the internals down.


Reassembly tricky to start with, with the baseplate retaining nub and bolt being a right pain. A cheeky dab of superglue to stop the spring flying  off and I was sorted, easily reassembling the magazine from there. The spring slides back up into the housing easily, and the bottom end is bolted down to the internal body.

To conclude – for eight dollars I think these are cracking bits of kit, and I am considering getting a box of five more to provide a lower capacity/lighter weight option than my MAG 190 rounders, which are stunning magazines (a review for another day yet again).

They work beautifully in my primary M4 (another post for another day), load easily, drop free easily and are lightweight and attractive, with a few visual and technical flaws, but nothing major. You can damage the mag by over-loading them, so it would be best to not load more than 100 rounds into the mag.

Dave out.
