Specna Arms SA-J71 CORE™ Carbine Replica

Specna Arms, in order to meet the expectations of its customers, presents the CORE™ line - a unique series of replicas that introduces a new quality on the airspeed replica market.

An affordable price combined with an innovative quick spring change system, great performance straight out of the box and high-quality components makes this series an excellent choice for both beginners and experienced airsoft players alike.

Specna Arms J-Series™ CORE™ carbine replicas are made primarily out of durable polymer reinforced with nylon fiber, making the replica lightweight and comfortable to use. Pistol grip, receiver, handguard with the gas tube cover, gas tube and the front sight post are made of polymer.

The most crucial elements, such as the barrel mount, dummy bolt carrier, rear sight, barrel and front sight are made out of zinc and aluminum alloy. The dust cover, safety, trigger guard and the stock are made out of steel.

Specna Arms J-Series™ CORE™ features a very good fit of the parts, ergonomics and low weight. In addition, the replica comes equipped with the ESA2™ quick spring change system. The system allows you to adjust the power of the replica without the necessity to disassemble the replica. To replace the spring, you just need to remove the dust cover, fold the stock and unscrew the screw holding the spring guide.

Features of the replica:

  • Receiver is made out of plastic
  • Low weight
  • Well-fitted
  • Metal hop-up chamber
  • 6.03 mm diameter precision barrel
  • ESA2™ quick spring change system
  • Additional M90 main spring included

  • Plenty of room for a stick battery under the dust cover (LiPo ready)
  • Full stock or folded to the side
  • Magwell spacer for easy magazine reloading
  • Original S-MAG hi-cap magazines

The replica is compatible with most types of Cyma, JG, E&L and Bolt magazines, the matching of magazines from other brands may require some minor modifications.

The replica has been fully adapted to work with LiPo and LiFe batteries.

The gearbox has 8 mm slide bearings and steel gears fitted on them. The system is secured by means of four anti-reversal latches. A light, made out of polycarbonate plastic piston is fitted with a full steel tappet plate increasing its durability. A type 0 cylinder and a steel circuit-breaker are also used here. The durability of the components allows for using M140 springs.

To buy an airsoft weapon in the UK you must have a valid airsoft defence.

This is not a licence, it is basically just proof that you intend to buy an airsoft weapon for use in airsoft.

An airsoft defence could be a UKARA or membership with the British Airsoft Club, and various other forms of defence.

You can only obtain an airsoft defence once you are over the age of 18.

To get an airsoft defence the law is that you should play at least 3 games of airsoft, and that you must have been playing for at least two months.
You can still buy an airsoft gun without a defence, provided you are 18 or older. If you choose to do this we would, by law, two tone (paint in a bright colour) parts of your chosen weapon. This is because an airsoft gun is considered a RIF aka Realistic Imitation Firearm, because they are so close to the real steel, whereas when you paint parts of it in a bright colour it becomes an IF aka Imitation Firearm. The reason being that the bright colours make it look less realistic to the public, and therefor less likely to be mistaken as real, were it to be used for any other purpose than airsoft.

When you order a gun from us you will need to add your defence details in the comments section of the cart. If you do not have a defence you will need to write the colour that you wish to be used for two toning your airsoft weapon.

Here is what's stated in the VCRA (Violent Crime Reduction) Act:

For airsoft skirmishing, the Association of British Airsoft is putting in place arrangements to allow retailers to check that individual purchasers are members of a genuine skirmishing club or site. The key elements of these arrangements are:
1. new players must play at least 3 (three) times in a period of not less than two months before being offered membership
2. membership cards with a photograph and recognised format will be issued for production to retailers
3. A central database will be set up for retailers to cross-check a purchaser’s details
4. member’s entry on the database will be deleted if unused for 12 months.
The defence for airsoft skirmishing can apply to individual players because their purchase of realistic imitation firearms for this purpose is considered part of the “holding” of a skirmishing event.
