Description

This Specna Arms H04 is a unique platform very similar to it's brother the SA-H01, rocking a super compact style receiver / handguard these guns are excellent when it comes to dominating all areas of the airsoft field.

This fan-favourite is built to the usual Specna Arms standard including a Zinc/Aluminium Alloy Handguard and Receiver which have undergone Anodizing and Powder Coating processes after a course of sand blasting to achieve an award-winning finish. The various trim aspects of the rifle (fire selector, screws, pins etc) are made from Steel to ensure long life and a lasting finish.

The replica is powered by electric is front wired to accept a NiMH or LiPo battery at the front either in an external battery bag, hidden inside a PEQ Box or simply taped to the front (sometimes simple is better). The sliding stock at the rear is a PDW style and has three locking positions to give you a choice of compact, pretty compact and really compact, and is made to tight tolerances so that there is minimal 'wobble' in the shoulder.

The handguard is a proprietary fitment primarily however it does have 20mm rail sections towards the front to allow for the addition of Foregrips / Hand Stops, Lasers and Torches positioned   A set of iron sights are included and come pre-attached to the RIF; we recommend leaving them in place for if your main sight ever fails and you need a last second backup. There are solid QD sling loops at the handguard and a loop at the stock so that you can run this RIF with any sling setup that you like.

The Specna Arms SA-H04 Airsoft Gun features their own brand of quick release system called Enter & Convert™, which makes changing your main spring much quicker than standard AEGs. Whilst the gearbox still needs to be removed to access the quick change spring, not having to disassemble the gearbox will save you a world of frustration and disapproving *tuts* from the other half as your replica is split into its' exploded diagram on the living room rug.

The 'Specna Arms Quality' continues inside the replica as well, where you will find some nicer parts than standard. The gears are a reinforced Steel set, as is the Spring Guide, the Cylinder Head and Nozzle are metal, the Piston Head made from Aluminium and a lightweight Polymer piston are all installed with the greatest care, and are thoroughly inspected upon leaving their factory, as well as when they arrive at both supplier and our facility.

If you love the Navy SEALs/Operator look, want to run a Special Forces loadout or just have a lot of love for the 'Black Bag Operation' firearm of choice and want a rock-solid build quality to go with it, there isn't a better choice than the SA-H01.
