  1. Great gun 5 Star Review

    Posted by Dave on 8th Feb 2024

    Plastic shell gearbox with metal gears.majority of black components are metal except for the gas block, front sight and body which are made from excellent quality polymer. Disappointingly the buffer tube on this rifle is not metal as it is on the by 032 . Rifle has all the manufacturers markings which make it look very realistic and shoots well with excellent rate of fire.

  2. Brilliant 5 Star Review

    Posted by Keith A on 12th Jan 2022

    Just received my D-BOYS Double bell M4. The build is very good and the weight is fine. This is a very accurate gun with lots of space for accessories. The FPS is around 330. I would totally recommend this to any one looking for a decent AEG at a great price. Would suit a novice or an experienced air softer.

  3. Good first electric gun 4 Star Review
