Banggu Seok Gunman goes the reviews an M416 Electric Blowback gel blaster purchased from Temu for a very low price, questioning if this budget product could compare to more expensive, Chinese-made models. He found that while the gun's design looks somewhat stylish and the firing speed is decent, the overall build quality is extremely poor, using cheap plastic that feels decidedly like a toy.
A presentation and review of the Double Bell M416 AEG by UK Airsoft and they have it in stock. Double Bell presents a robust HK416 family replica with metal externals like the SMR type handguard, upper and lower receiver, outer barrel, and buffer tube. The only polymer parts are the pistol grip and adjustable stock. The SMR rail, equipped with three rail sections, allows for customization of accessory placement or weight reduction.
PlaSSo shows his ongoing project of converting an Academy Airsoft M416 (HK416) AEG into an AR-57 AEG. This conversion allows him to use the P90 AEG magazine on this AEG. It is just a project, but if you are interested in one, there are already AR57 AEGs in the market. Where? Just ask your friendly airsoft retailer near you.
