Specna Arms SA-C03 CORE Carbine Rifle

Specna Arms
  • Adjustable Stock
  • Rear Flip-Up Ironsight
  • Part of the SA Core Range

Based off the rifle length M4A1 used by the US Army and Marines this rifle is a high quality replica built by Specna Arms as part of their CORE beginner rifles range.

Full description


This rifle is part of the CORE range, targeted at beginner Airsoft players who are new to the sport, being a cheaper alternative to the full metal guns these weapons are made from high quality polymers to reduce the overall cost of the weapon without the loss of quality. The weapon features a full polymer external design, except for the outer barrel, hand-guard and internals where the strength is required. This gives the weapon a light feel, allowing for quick manoeuvring in CQB situations.

The weapon features a removable flip up rear ironsight which is attached to the top 20mm RIS / RAS rail, 20mm being the most common type of Airsoft rail on the market today, giving you plenty of options for aftermarket parts from a wide range of brands. The top rail of the weapon is designed for attaching sights and scopes, as well as red dot and holographic optics. 

The rifle features an adjustable stock, which can be adjusted up to six positions for different sized users and features a rubber butt plate to prevent slippage whilst shouldering the rifle. The stock also doubles up as a battery storage compartment, allowing for larger 9.6v Ni-Mh to fit in, as well as the smaller 7.4v LiPo, giving plenty of opportunity to use the same battery between multiple weapons.

The front of the weapon has a barrel with a removable flash hider which when removed reveals a 14mm Counter Clockwise thread which can be used to attach a wide array of silencers, suppressors or even more advanced tracer units. The hand guard is also removable, which is done by  pulling back on the D-Ring and sliding the parts out of the way. This allows for aftermarket handguards to be attached, or for the tech enthusiast the entire handguard / d-ring and front post can be removed to attach a free float handguard.

The weapon also comes packaged with a pair of rail panels designed to make the weapon more comfortable to grip, as well as an included vertical foregrip to make the weapon easier use. These are great additions as they give you a great entry into the attachments which can be fit to the rifle, and allows you to deck the weapon out right out of the box ready for play.

Internally the weapon features a fully adjustable hop-up unit, designed to add range and accuracy by adding stability to the shots, and can be adjusted to support a wide range of BB weights. The hop-up is also adjusted by a radial adjuster rather than the standard gear system seen in older AEG allowing for higher accuracy of movement when setting the hop-up. The weapon's gearbox also features 8mm slide bearings and steel gears to enhance the lifespan of the gun, and features Specna Arm's EAS Quick Spring Change System, allowing you to easily and quickly remove the spring and replace it with a stronger or weaker one depending on the FPS limits of your local game site.

This rifle is perfect for those Airsoft Skirmishers who are getting into playing, for those who are looking to get a great beginner rifle, or for those who are looking for a great low cost rifle as a base for modifications.
