In case you're wondering why this keeps getting asked its because the Tech T works a bit differently then the stock bolt.
It's a common problem for the bolt to not sit back properly and block the feed neck. The Tech T bolt gets this problem fixed by upping the lpr, which in turn puts more pressure on the bolt to hold it backwards. Werd..
Its a pia to adjust but i love mine now that it works!
