Basically a scam - Mars Trigger AK FRT Kit Trigger

From the worst complaint down, installing in a ZPAPM70: 1) the retaining clip is some ~7mm too long, so it will not fit and you cannot install the system. 2) I called MARS customer service and they basically said "yeah, this is a common complaint, we'll add you to our list for when the fix comes out but not sure when that will be; just keep an eye out for our email or phonecall." 3) as a final sale item, you cannot return it, so there went $300 out of your pocket. 4) The trip bar and trigger cam have a very janky fit and they had milling tabs on them I had to clean off so there arent sharp bits of metal that stuck me; they're also free to wobble around in the reciever which leads me to believe that if the retaining clip did fit, the system would only function part of the time. 5) the trigger looks as if it were cast by a 5-year old and there was zero attempt to clean it up. After paying $300 for the few ounces of metal this is, you would expect something that looks far better than a toddlers science fair project. CONCLUSION: this product should be, at most, $45 including shipping; the parts do not all fit so you cannot even install it. You can't return it, and the quality is entirely ka-ka.
