Specna Arms SA-B01 M4A1 Carbine Assault Rifle

Built by Specna Arms to the highest quality these weapons are alloy in all the right places, with an alloy buffer tube, receiver, sling plate, outer barrel and carry handle, with a polymer stock, pistol grip and hand-guard. The weapon features various trademarks and stickers which all add to the weapon's realism, with a US Navy insignia on the magazine well.

The receiver features a top 20mm RIS / RAS rail which is revealed once the carry handle has been removed allowing the attachment of a wide variety of sights and scopes, and is the perfect home for a holographic or red-dot sight. The receiver also features a rear buffer tube sling plate which allows a variety of single point slings to be attached, and is made from metal to ensure that it is durable enough to take all the rough and tumble that comes along with a days skirmish.

The hand guard is based on the traditional standard hand-guard for an M4A1, and is designed to split just like the real thing, and is also where the batteries are stored inside the weapon. The hand-guard can also be replaced with other standard type M4 hand guard, and if the front post sight and d-ring are removed supports a wide range of aftermarket hand guard.

Internally the weapon contains everything you would expect from a modern Airsoft replica and more, with Silver wiring for low resistance, a v2 front wired gearbox with quick change spring system, 8mm ball bearings and is compatible with most Ni-mh, LiPo and LiFe batteries. We recommend a 7.4v LiPo stick or crane stock Tamiya battery. The weapon also features an adjustable hop-up system which is designed to add spin to the BB to add range and accuracy, and is fully adjustable to allow support for a wide range of BB weights.

This rifle is perfect for those Airsoft players who are looking for a traditional looking M4, but with plenty of strength and durability. This rifle is a perfect beginner weapon because not only is it excellent quality, but leaves plenty of room for external upgrades, with plenty of options for compatibility with aftermarket parts.

Special Instructions

The externals of the replica are metal where they would be on the real world gun. This includes things like the outer barrel, handguard, and receiver. If a real world gun has polymer parts then the gun will still be marked as full metal externals, examples of this would be an M4, where the Stock and Pistol grip are always made from Polymer.
