Description
This Airsoft Electric Gun is based on the tried and tested M4 platform, and offers a rock solid external build quality, coupled with Bolt's seriously strong recoil system which will rock your world. The outer barrel assembly, handguard, receiver, buffer tube 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. Due to the recoil system taking up most of the buffer tube, your battery space is in the enlarged stock pad, and is best suited to a 7.4v Stick LiPo. To access the battery compartment, simply pull backwards on the stock pad until it comes out, and push it back into place when you are done. 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 a 14mm CCW thread for suppressors, which is accessed by unscrewing the flash hider once you have removed the grub screw from underneath.
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.
Do you want an M4 platform replica which offers incredibly strong recoil, coupled with tough internals to keep up with the best and a rock-solid external build quality that is unrivaled? Look no further than the Bolt B4 CQB B.R.S.S.
