If you’re working on an old-school-cool build or need a simple and solid starter platform that can be modified to suit almost any battlefield need, the Specna Arms SA-F11 FLEX™ M4/AR-15 CQBR; X-ASR MOSFET should be on your radar. A predominantly high-density polymer build with an alloy outer barrel and trim parts, the SA-F11 makes a great starting point for a custom build, keeping costs low so you can kit her out as you see fit. Inside, the SA-F11 is well equipped, based around the prolific version 2 gearbox with an alloy shell, steel 18:1 ratio gears, 8mm bushings, and the ESA quick-change spring system for easy power tuning. Also inside is a 6.03mm tightbore inner barrel and rotary HOP-up unit, providing competitive accuracy and range along with an FPS boost from the tighter barrel’s improved air efficiency. This, the latest version of the SA-F11, is also equipped with the Gate X-ASR smart fuse MOSFET, providing diagnostics and a snappier trigger feel while eliminating trigger lock-ups in semi-auto. That’s a lot of gun for not a lot of money! Whether you need a cheap backup or loaner AEG or want to get into the sport with a proven platform with plenty of future upgrades and customisation options, the SA-F11 FLEX™ M4/AR-15 CQBR; X-ASR MOSFET is a great option. Ideal for military-style builds but truly living up to the real steel AR-15’s nickname “Barbie for men”, the sky is the limit when it comes to kitting this CQBR out!
