Description

The rifle is constructed mainly from Polymer, with a Polymer Receiver, Sling Plate, Buffer Tube, Hand Guard and Pistol Grip with Alloy Barrel and Internals. The weapon comes pre-fitted with a unique looking Hand Guard and Compensator, which can be removed by releasing the two screws at the front of the rail, allowing the compensator to be simply pulled off to reveal a 14mm CCW Thread and standard M4 / AR Flash Hider for attaching Silencers and Suppressors. The weapon features a highly customisable top rail, which in total is 21'' in length, and fits together like on piece, allowing for a huge variety of Sight and Scope setups, as well as Magnifier and Holographic Setups. The Hand Guard also features two 3'' and a bottom 3'' 20mm RIS / RAS Rail for attaching Grips, Bipods, Torches and Lasers to your weapon. The rifle is rear-wired, meaning batteries are stored in the 6 position Adjustable Crane Stock, which accepts crane / butterfly style batteries. The Stock also features a rubberised Butt Plate which prevents slippage whilst wearing large rigs and vests. This rifle is perfect for those who are beginning out in Airsoft, and are looking for a unique looking piece which will make them stand out on the field.

Special Instructions:

Please note that the Rear Sling Plate is made from plastic, and the rifle sling is basic, and is for looks. Should you want to use the rear sling plate it is suggested that you replace it with a Metal Version, such as the: NUPROL M4 Sling Plate AEG, and a heavy duty sling such as the NUPROL One Point Bungee Sling. Should you need help fitting these parts you can give us a call on: 01484 644709.

The Rail Integrated Compensator is removable by first removing the screw on either side, and then pulling off carefully by hand. This reveals a 14mm Counter Clockwise (CCW) Thread, which allows the attachment of Silencers, Suppressors and Tracer Units.

Occasionally cheap batteries and chargers are provided with AEGs, but this will vary depending on batch. These batteries can often be of low quality and are considered free gifts and will not last as long or provide as much performance as other batteries and chargers we sell. We recommend that you assume these are not going to be present in the box, and purchase an aftermarket battery and charger and if they are included, keep the free battery and charger as a backup. The correct battery for this AEG is as follows: NUPROL 9.6v 1600mAh Ni-Mh Crane Battery, and NUPROL Compact LiPo / LiFe / NiMh / NiCd Balance Charger

Joule Charts

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.

This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.

In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.

Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
