During the mid/late 2000’s, or my early days of my bbLARPing, I was obsessed with having different guns for different tasks. I “needed” the M16A2 for outdoor games; I “needed” the MP7 for CQB use; I “needed” the M4 for general pickup games, and on and on and on. As such I always had a shitload of unused airsoft guns lying around and taking up space. In 2020, after about a 3-4 year hiatus from “serious” playing, the decision was made to come back to the sport so the WGW team could play with our homies and customers that we had met through the company. At that point, I had gotten pretty tired of toy guns taking up too much space and had decided on buying just one gun.
Luckily for me, the Sig MCX AEG (with quick change spring) had just been announced for release… right around the same time some pictures started circulating of GEN Miller’s PSD of GS dudes armed with LVAWs. Having also just completed the Modern Warfare remake a couple of months prior, the MCX hype train was at full speed and I was an unwilling passenger. I called my local Airsoft Extreme store, put some money down, and had my MCX a few days later.
Since then, the MCX has been my go-to for almost all of the games I have attended. Even with its relatively short barrel length and stock internals, it has performed well in a variety of different field environments and rule sets. From zero-foot MED CQB in LA speed fields, to MOUT gameplay at George Air Force Base, to hill-to-hill engagements in the forests outside of Reno; the MCX has proven to be a sound choice for the “just one gun” approach, as its quick-change spring and in-spec MLOK slots make it possible to fine-tune its performance and capabilities based on what I’m doing.
With regards to how the gun shoots… I’m of the mindset that all airsoft guns within an upgrade limit (ex., 400FPS) all do the same damn thing. I’m not the kind of person to get tied up in trigger response, rounds-per-second (who the fuck uses full auto anyways?), or tightbore barrels. The AEG fires when I pull the trigger and with good enough response, which are all that matter to me. In terms of “accuracy,” I have hit players presenting partial silhouettes out to ~150ft using the included downgrade spring (398FPS with .20) and .28 bb’s, which is way more than I could have asked from my old Marui guns out of the box. Since 2020JAN I have not changed out anything internally.
The only issue I have with the MCX is magazine fitment – it is super finicky with what mags fit (and fit well), and I’ve been lucky that the PTS EPM1s fit and feed decently enough. I’ve also had success with Elite Force “Dogs of War” metal midcaps and plastic boxset mags, as well. My particular MCX does NOT work at all with Evike, Amoeba and similar PMAG style “large” midcaps – my other friends with (later DoM) MCXs are able to use these mags without issue.
At current, I have my AEG setup with:
– Sig Optics Romeo5 on PTS Unity Tactical Mount
– Edgar Sherman Design sling
– Modlite 18650 OKW on Arisaka Defense Side Scout Mount
I also throw on my EoTech G33 magnifier/Unity FTC mount and L3 PEQ-15 as the situation dictates. The in-spec mounting holes and rail slots allow authentic weapon accessories to be used. Additionally, the MCX is compatible with actual SIG rifle stocks and handguards, though battery fitment/placement may vary depending on which one is used.
At its most basic level, the MCX is just another version 2 gearbox AEG that takes M4 mags – it does, however, come with some much-needed hardware updates for the 21st century. While they may seem minor in the grand scheme of things, the discerning end-user will find these tweaks very welcome as it allows the MCX to cover all the bases that most airsofters would need for general-purpose use.
