[ARCHIVED THREAD] - New Upper Build HELP

Posted: 2/27/2013 12:32:39 PM EDT

I know,I know, this is a really silly question but this is my first attempt at building a .22 upper so I need a bit of guidance. I have a Spikes biohazard reciever, BCG, m4 profile BBL and charging handle so far and am attempting to get all the piece parts in one place before I begin the upper assembly. Here's my question, I know I need a BBL nut is there any other hardware aside from a rail kit, I'll need to assemble the BBL to the reciever? I'd like to purchase all the little hardware pieces from one place to avoid pay a shipping charge for each $10 item. Your patience is most appreciated.

Barrel nut is all you need to get the barrel on the receiver.
After that you will need to install the gas tube and gas block unless it is on the barrel already.

I haven't built a .22 upper either, but that should answer your barrel question.

The .22 is a blow back design, correct, no gas tube etc., should be easier to put together don't have to line up the gas holes and barrel bolt notches.
