Outstanding kit! Once together, it’s a tight,compact super fun machine!
I got the accessory kit with it as a package: sling, flip up sights, thumb rests and the flashlight. I was able to attach my suppressor to the weapon and have the majority of it internally – inside the kit, which was the main selling point for me.
BE ADVISED- I could NOT get the kit fully together on my gen 5 g19 and here’s why; I had the beavertail backstrap on it prior to getting the kit.
After several frustrating minutes of trying it on my own, I called and had a conversation with an extremely patient Jay F. with customer service. Jay soon had me removing the beavertail blackstrap and it slid right in (giggity). So if your putting a beaver tailed weapon in the kit, remove the beavertail!
I put a cyelee T10 red dot on the picatinny rail and the flip up sights are perfect fit for the co-witness. The sights did arrive a little off center, but that’s an easy fix at the range.
Folded up this fits in a small backpack. Getting it “ready” quickly is not a problem.
After a few hundred rounds with this one, I may do another for a different caliber.
Highly recommend! And another thank you to Jay!

Works and feels amazing! Took it to the range a few days after getting it, and couldn’t be happier with the performance. Everyone thought it was pretty cool, and even let a few people try it out! Will be ordering another soon!
