The Adaptive Armament M4 series has finally hit the market to impress those looking for optimum performance from a brand new airsoft gun. The M4 SBR comes with a 10" MLOK hand guard perfect for a smooth platform that you can add rail segments onto for utilizing accessories. There is an ambidextrous fire selector and magazine release perfect for users that need to manipulate the weapon with either hand. Quickly access the hop up chamber once you lock back the imitation bolt.

Adaptive Armament has included a programmable MOSFET with integrated battery protection and adjustable firing modes. This is excellent for protecting your gearbox from locking up and becoming damaged. The adjustable firing modes allow you to control the ROF and burst options on the airsoft gun. Combined with the micro switch trigger, the AA M4 SBR shoots with great response. On top of all that, a 6.03mm tight bore inner is preinstalled to excel in range and accuracy. The reinforced 9mm bearing gearbox hosts the reinforced piston and padded cylinder head to have this ready to handle a LiPo battery. Ease your mind knowing that the low resistance wiring combined with the MOSFET will also protect the airsoft gun from the high current of a LiPo battery. Lastly, a easy change spring system allows you to swap out the spring without the hassle of disassembling the entire gearbox. Overall, the Adaptive Armament M4 series is on point when it comes to satisfaction and performance.

Covid-19 Crisis

Although we are working to strict safety guidelines and on reduced staffing, we are still taking and shipping orders. All orders are shipped by courier and our processing and shipping times are currently on time. Please bear with us if you are sending an email as we cannot guarantee our normal 2-3hr response time at the moment although we are operating an Online Chat system during working hours. 



We will always try to send your order within 24 hours but this isn’t always possible and we ask you to please allow 5 working days from placing your order before getting in touch if you have selected a free service. International orders are generally delivered in 7 to 10 working days although this cannot be guaranteed. If stock is not available we will contact you to let you know a delivery date.



We will do everything we can to ensure your order is shipped on time and on the best possible service. From time to time we are let down by couriers, bad weather and unforeseeable delays. Your order will still have been sent on the fastest service possible and at the relevant cost and so we are unable to refund delivery charges on these occasions.

Our priority service is available for £3.95 which provides a 2-3 working day service and guaranteed next working day delivery is available for £7.95 for all orders placed before 4pm.
