Description

This electric-powered Airsoft replica is a DMR style rifle based on the SR-16 platform, which is a long-barreled variant of the AR family. The outer barrel assembly, handguard, receiver and various trim aspects are made from a combination of Alloy, Aluminium and Steel for a long lasting finish which provides a realistic weight, feeling extra-incredible when combined with the vicious recoil. Where Polymer has been used (pistol grip and stock) they are a high density Nylon Fiber which is a tough, quality material that feels great to the touch.

The RIF is a rear-wired design, and houses a Mini Tamiya connect at the rear of the stock. Thanks to the M16 style solid stock you have massive amounts of space inside to accommodate pretty much any battery. To access the battery compartment, simply open the door at the rear of the stock by pulling down on the spring loaded release. The handguard and receiver are 20mm railed which allows you to attach all manner of accessories, to build your dream AR platform rifle. The end of the barrel features the typical SR-16/SR-25 thread to accept a proprietary over-barrel suppressor (not included).

The Bolt Recoil Shock System (or BRSS) is the beating heart of what makes these replicas awesome, and provides a heavy, weighted recoil when you pull the trigger. This gives the user a strong recoil effect without having to mess around with gas systems which can be unreliable. The replica features a reinforced Piston which actuates an ERG style recoil mechanism in the rear of the RIF, delivering a strong kick into your shoulder every time the replica cycles. This means you get to enjoy the joy of realistic recoil, with the benefits of high capacity magazines and consistent performance. Unlike traditional 'recoil systems' which simply move the dust cover backwards and forwards, this style of recoil involves a weighted piston moving around at the rear, which brings a whole new level of realism, and feels incredibly satisfying.

Included in the box is a 300rnd High Cap magazine made to a wonderful standard, and a spare Mini Tamiya connector with wiring and extra pins, to help you either replace or extend the current wiring in the RIF.

If you're looking for a DMR-esque rifle which is based on the AR platform design, but offers something slightly different to your run of the mill M4, then the Bolt B4 MK12 MOD-1 Fixed Heavy is a great place start looking.

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.

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.
