The Modern Hunter and ATRS are in the same boat as NEA when they first started up. Quality issues with parts and design flaws. I use the term design loosely because most of the dimensions for the receivers are standard AR dimensions and all the parts used to assemble the rifles are sourced from other manufactures.
The only difference is ATRS charges 4x the amount for their product while offering the same poor customer service/after sale support. One doesn't have to spend a lot of time searching the internet to find the information to support my statement. Unfortunately in the past anything negative posted about the Modern Hunter here was deleted although it seems something has changed recently.
Hopefully it gets worked out so all those that have purchased one can feel better about the thousands they have spent on their rifle.
WOW!! What a load of crap! The customer service I have recieved has always been stellar.
