Great quality

I love the work. Just wish there was more options to choose from so I can build all my calibers. I need to replace all my old parts with juggernaut tactical parts. Sell a do it yourself kit for wrapping. That would be cool.

Awesome product

Excellent craftsmanship and quality. Significantly better than most of the competitors. I’d definitely purchase from them again in the future. Customer service is just as great as the product. Had a couple questions answered within a timely manner.
