Description

The Specna Arms ONE™ series of airsoft replicas represents a significant step up from the more affordable Specna offerings, providing the user with high quality and full metal externals combined with solid uprated Specna internals and an impressive and hard wearing external finish.

This MK18 mod.0 style AEG replica provides a faithful representation of an early 2000s US Navy SEAL direct action rifle of choice. Also known as the CQBR (close quarters battle receiver) the Specna SA-B02 excels at exactly that, close quarters. The 10.5" barrel provides enough length for airsoft purposes that you will not be at a disadvantage using this CQB optimised set up outside but grants amazing manoeuvrability when clearing rooms and firing around obstacles.

Starting from the front end of the replica we can find a late gen birdcage style flash hider with a cut-out for wire cutting (you wont be using this!). This threads onto a 14mm CCW thread on the outer barrel, allowing you to add a muzzle device of your choosing. A KAC style QD suppressor suits this replica perfectly, especially if you want to imitate the mod.0 iteration of the MK18. The fixed front sight/ dummy gas block coupled with the "chopped carry handle" style rear sight provide a simple and practical solution to sighting, meaning an extremely low chance of breakage and a significantly lower likelihood of snagging on gear and equipment when compared to modern flip-up irons. The 20mm rail on the receiver provides a flexible mounting surface for an optic of your choosing. The receiver is comprised of a mix of Aluminium and Zinc alloy and is sand blasted and finished with powder coating and then anodised matt black, meaning you would be hard pressed to tell this and a real AR15 apart. Specna's own "Nano coating" finish is applied over the top, providing extra scratch resistance. All screws, pins and other structural components are made from steel, giving them a long life and preventing stripped screws if you venture into its internals. The metal receiver also features a hologram of authenticity and a unique serial number for theft prevention.

As you might expect, everything that would be metal on a real AR15 also is on this AEG. The crane style stock and finger ridged M16a2 pistol grip are made of a high-density polymer and feel great to use. The surface of these components is textured to provide positive grip over the rifle. Use of a crane style stock not only fits the MK18 mod.0 look perfectly out of the box but allows you to fit a monster battery inside with quick and easy battery changes, suiting the practical skirmisher as well as the Milsim crowd. The sliding stock mounts to an AR15 buffer tube, allowing an easy change of stocks for a custom look. Mounted to the buffer ring is a sling plate, allowing multiple options for 1 point sling configurations and can even be coupled with the provided sling loop on the front sight if you would rather use a 2 point sling solution. The magazine included in the box is a 300rnd high capacity clockwork wound design with "5.56x45mm" and "Restricted to Law enforcement and military use only" for added authenticity.

Internally this replica features Specna's Enter & Convert™ quick change spring system that means once the gearbox is removed from the body, the main spring is easily accessible for rapid changes in output power. Other internal parts include a Steel Spring Guide, reinforced Steel Gears, a lightweight Polymer Piston, Aluminium Piston Head as well as an Alloy Cylinder Head and Nozzle. The mock bolt stop is functional and allows you to make easy HOP adjustments without having to hold the charging handle to the rear. The 6.03mm diameter inner barrel provides a stock "tight-bore" barrel, aiding in accuracy and improving air seal.

If you are looking for a classic AR15 style replica from an era before negative space attachment systems and low profile gas blocks this what you want. The combination of classic styling and the ability to mount any accessory you could possibly need without purchasing extra rail sections means your SA-B02 can be as modern as you make it!

Special Instructions

These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.

FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.

Tap the tabs below to open the relevant chart for your replica.
