Wait time was about 4 months. It took a little longer than estimated. I have waited longer for lesser quality HK clones. The build quality really impressed me. All I had to do was modify my trigger pack to work. First time out it ran 100% in 223. I had a few jams with the 308 but I think that was a bad belt or me not supporting the belt. It's awesome to buy something that actually works out of the box.
