This is a awesome m4 gel blaster with secure packing. It requires batteries to work. My kids like it. So far no complaints from them.


Really good m4a1 gel blaster from zhen. Great range and rate of fire.... fairly accurate. Only issue is that there is no semi automatic. I waited for the package for one month and finally arrived, the quality is excellent. The weapon itself is slightly smaller in scale than the combat model, but also good. I am very pleased with the purchase


Great quality gen 8 and tons of fun. Comes neatly packaged with easy to assemble english instructions.
Not only is this one of the best gel blasters that I have purchased but they also have excellent customer service. They are very pleasant and quick to respond.
Would highly recommend purchasing and getting some friends together for a great time!!


Es ist meiner Meinung nach die beste billige Spielzeugpistole, die per DHL versendet wird und in 2 Tagen wirklich schnell ankommt. Qualität ist super


The m4 Gel Gun it’s self feels right worth the 90usd if you shoot it at someone it will leave a red mark and maybe a welt.


Got the product. Unboxed. Immediately put battery on charger and put supplied balls in water. Waited 5 hours for the balls to be ready. Battery was green. Filled the mag up and went outside. Shot for 2 minutes and no issues.


gen8 has a versatile modding oppurtunity, zhenduo sells it at the lowest price! the industry crusher is worth its name!


Great product!!!….If anybody knows where to get another mag please let me know.


Good accuracy, easy to use and very fun to have some gun wars with


The quality is amazing and is worth every pennie
