Excellent product. Been having a blast with it.

Great product. Very fast delivery. Great print quality. Easy to recharge. Very secure barrel lug attachment. Very secure attachment to picatinny rail. However, with the picatinny mount version do not expect to quickly attach and remove like with a nerf rail. I will be buying more of these.

Amazing product that does its job and does it well. I love AmmoCounter's product and have literally bought every version since V2. Super easy to slap on any blaster and use and the ability to customize various settings on the counter is really awesome. You cant go wrong picking one of these up and their is a reason many veteran Nerfers have on on their blasters

So this is the 4th one of these I have bought from AmmoCounter (v2, 2x v3 and now the V4) and each time the product gets better and better while still maintaining the straight forward and simple function that drew me to these in the first place. His print quality is excellent and the units are a breeze to install and use, and the customer service and support is excellent. I can't imagine running a primary blaster in local wars, competitive foam, or Humans Vs Zombies without one of these units on my blaster. TK-1138 Nerf
