So Far so good

I have not been able to test it thoroughly yet; however, we were able to range accurately to 14,400 yards and tested up against a Halam! Our ranged target was spot on! I will dive into the ballistic engine within the next several weeks, as Applied Ballistics, along with any engine, will require a lot of tweaking to accommodate changes in the arc over ultra-long-range targets beyond 1 to 2 miles. More to come.

Great product!

I was a little skeptical since I’m not a huge fan of having Kydex (hard pouches) on my kit. However, the attachment system is great. Super easy to install and secure. The pouch itself holds the radio really well even with the extended battery.. The design is low profile and does not come off as bulky in anyway. I haven’t tried it, but it appears they have attachment points so that you can rotate the pouch to have different wiring or antenna placement.

Best tactical purchase ive ever made. Much better for training purposes and a lot less neck fatigue.
Saved some money at the same time!

There’s many great compact weapon lights on the market, but this is the only one for me.

Great purchase

I’m extremely happy with my purchase. It is exactly what I was looking and hoping for. Customer service was excellent. Sam did an amazing job. He helped me with my color choice (perfect by the way) and with making sure it was shipped and delivered very quickly. I can’t say enough about the bag and the customer service I received.
