| Hi guys ..... I'm new to this self build concept and need a little help. Is it possible to convert an available, dedicated 9mm, stripped, upper receiver for a 223/5.56 build by drilling or machining the missing hole for the gas tube or are there other differences between these two versions of upper receiver? If it is possible to convert the 9mm receiver for normal gas impingement and rifle project is there any guide information or instructions available? |
