I own an MDRX in 308. Here is my take.
The rifle itself works ok but it can be a little finicky. After giving it a little cleaning and lube, I took it to the range and found that the trigger would lock up after every shot. I had to take it apart and re-assemble it several times before I could get it to work reliably. It has to be re-assembled just right to work well. Truevelocity ammo does not work well in this gun due to the ejection system. The plastic cases are too flexible for the ejection cam to work properly. Even with brass cases 2/3s of the case mouths have a dent due to the cam having to push the front of the case into the ejection well. Sometimes this dent will get caught up in the ejection well.
The big issue is customer support. It took about 10 months from payment to delivery. I ordered the Mantis fore end and the torque wrench. The Mantis, torque wrench and barrel came trickling in during the 10 month wait with the chassis finally arriving. The estimated ship date on the web is set at order time but does not get updated. I have had the rifle for about 2 years but the website still shows it yet to be delivered. The on line registration also does not work. No one answers the phone and left messages go unanswered. Email response is spotty and when I did get a delivery update, it was never met. My emails to support on my issues were met with a terse "fill out the warranty repair card and send it back". There was no way I was going to send it back and wait another 10 months. I just fixed the issues myself as best I could.
The Mantis fore end right leg would keep collapsing at every shot. Emails to them on it went unanswered. I noticed that BLK LBL was the manufacturer so I contacted them. Their customer service was great and they sent me a replacement as soon as they received the defective unit. However, since they are in Canada, I had to spend $50 to ship it there USPS. It took Canadian Customs over a month to process it through so that was another 2 months lost.
My plan was to order additional barrel kits for it but after my experience that will not happen. It was unfortunate that I got the urge to want a 308 bullpup when I did. If I had waited a few years, the crop of 308's coming out now would have been a better choice.
Just my opinion.
