I finishe this a couple of months ago and had problems the first time out. the trigger would not reset and there were problems feeding. it would not feed links. Since .308 is so expensive I decided to convert it to 30-06. I modified a 1919 booster and made a new front cartridge stop. it uses standard 1919 bbls. I rand some dummies through it in links at home and it seemed to work but it would not feed at the range, it took about an hour of tweaking to get it working but once it did it ran good.
