Description
Sig Sauer MCX Virtus ProForce (Black)
The Sig Sauer MCX Virtus ProForce is an officially licensed airsoft electric rifle modelled on Sig Sauer’s modular MCX Virtus platform. ProForce is Sig Sauer’s own airsoft line, and this AEG is produced for it by VFC, a Taiwanese maker well regarded for accurate external detail and solid internals. The result is a replica with correct trademarks and proportions that feels like a serious piece of equipment from the moment you pick it up.
The MCX has become one of the most recognisable modern rifles in the world, and the Virtus version is its most refined form. This black ProForce AEG captures that look with full metal receivers, a slim machined handguard and a compact telescoping stock, while keeping the internals simple and familiar so it is easy to maintain and upgrade.
Build and materials
The upper and lower receivers are full metal, giving the rifle a rigid, quality feel with no creaking or flex. The handguard is CNC-machined aluminium with M-LOK slots along its length, so you can add short rail sections, a torch, a hand stop or a foregrip exactly where you want them while keeping the front end slim. A continuous top rail gives plenty of room for optics. The stock and furniture are metal, and the telescoping PDW-style stock has three positions so you can shorten the rifle for close-quarters play or extend it for a steadier hold.
Performance and internals
Inside is a full metal Version 2 gearbox driven by a high-torque motor, with an integrated MOSFET that protects the trigger contacts and makes the rifle well suited to LiPo batteries. The rotary hop-up is reached through a functional mock bolt that locks back, a realistic touch that also makes adjusting the hop-up quick in the field. A quick-change spring system accessed through the stock allows you to swap springs without opening the gearbox, which is useful if you play at sites with different limits for indoor and outdoor games.
Handling
The MCX layout will feel familiar to anyone who has used an M4: the selector, magazine release and trigger are where you would expect, so reloading and changing modes become second nature. The compact PDW stock and slim handguard keep the rifle well balanced and easy to manoeuvre through doorways and dense woodland. Fire modes are safe, semi and full auto.

Compatibility
The M-LOK handguard accepts standard M-LOK rail sections and accessories. The Version 2 gearbox means many common V2 parts can be used when servicing or upgrading. Because the MCX stores its battery differently from a standard M4, check the space available on your exact variant before buying a battery, and choose a LiPo pack with a connector that matches the rifle. Use magazines designed for this model or confirmed by us as compatible.
Care and maintenance
Unplug the battery after every game and store it separately at storage charge. Use seamless, good quality BBs, and clean the inner barrel periodically with a rod and lightly dampened patch. Keep the M-LOK slots and rail free of grit, and wipe the metal receivers with a lightly oiled cloth now and then to protect the finish, especially after wet days. Do not oil the hop-up rubber or barrel.
Who is it for?
This rifle suits players who want an accurate, licensed MCX with real-steel style markings and a quality metal build, whether as a main gun for skirmishing or as the centrepiece of a modern milsim loadout.
Please note: Battery and charger are not included. Always wear suitable eye and face protection and check your site’s power limits before play.
