    I bought the conversion kit with 3 mags + 10 extra for $205 plus shipping. Great deal and fast shipping. I am very pleased with my purchase. I would buy it again. The mags will sell for $30 a piece so it was great deal. I have run 500 rounds through it. It has had 1 failure to feed, and 2 failures to extract. That was on the first time out. Last training session no issues

    I've used this quite a bit since I've gotten it. I utilize it with two main purposes, the first is teaching my kids to run an AR style rifle without going through hundreds of dollars of ammo. To this extent it has run almost flawlessly. There have been minor hang ups with the extractor not pulling the used case out, but this could also be due to the quality of the ammo we were using. Either way, it makes for good training on how to clear a malfunction.
