Description
Specna Arms SA-H12 ONE Carbine Replica – Tan
The Specna Arms SA-H12 ONE is a 416-style M4-pattern carbine AEG from Specna Arms’ ONE series, here in tan. The desert finish gives it a smart, modern look that suits arid, multicam and coyote loadouts, while underneath it is the same solid, well-specified rifle as the black version.
The SA-H12 is made largely from a uniform zinc and aluminium alloy, with steel reinforcement in the areas that take the most stress. It has the SMR-style handguard and sliding stock of the 416 platform and is a sound choice for new and experienced players alike.
Build and materials
The SMR-style 416 handguard has a 12 o’clock rail for optics and removable 2-inch and 3-inch 20mm Picatinny rail sections that you can place where you need them for a torch, laser or grip. QD sling sockets sit on both sides. The 10.7-inch outer barrel has a 14mm counter-clockwise male thread for suppressors and tracer units, and the pistol grip and stock are high-density polymer.
The six-position 416-style sliding stock has an alloy buffer tube and built-in sling bars, and lets you adjust the length of pull to suit your kit.
Performance and internals
A rear-wired Version 2 gearbox with steel gears, 8mm ball bearing bushings and a steel spring guide drives the rifle, and Specna’s Enter & Convert quick spring change system lets you change the main spring without opening the gearbox. This is handy if you play at sites with different power limits. The 6.03mm, 290mm inner barrel and rotary hop-up give consistent shots; the hop-up adjuster is reached through the ejection port after pulling back the mock charging handle.
Battery and handling
The battery lives inside the stock and is accessed by rotating the butt plate 90 degrees. Specna recommends a 7.4V 1450mAh LiPo with a mini Tamiya connector. With an overall length of 73cm collapsed and 81.5cm extended, the rifle is compact enough for buildings and comfortable on longer woodland games.

Compatibility
Takes standard M4/M16 AEG magazines from most major brands, and tan magazines are widely available if you want to match the finish. Version 2 upgrade parts fit the gearbox, the rails take standard 20mm optics and accessories, and the 14mm CCW thread suits most suppressors and tracers. Use a 7.4V LiPo sized for the stock.
Care and maintenance
Disconnect and remove the battery after every game and store LiPo batteries in a fire-safe bag at storage charge. Clean the inner barrel periodically with a cleaning rod and a dry patch, and use good quality seamless 6mm BBs to protect the barrel and hop-up rubber. Wipe the body down after wet or muddy games and let it dry before storing. Leave the gearbox alone unless you are confident working on AEGs; when you swap springs, use the quick-change system rather than stripping the gearbox.
Who is it for?
Players who want a 416-style carbine in tan with a solid metal body, good internals and easy spring changes, for woodland, desert-themed or CQB games.
