I first posted in October, and although I've found time to type and post, it is only recently that I've been able to followup on this project.

I have an A4 upper with a Colt Gov't. A2 barrel needing installation.

I have an M16A1 upper with the proper barrel, also needing installation.  (I'm still short a gas tube, bolt carrier, and charging handle, so I won't be shooting it same day, but can install the tube myself).

I don't have anything to attach my vise to and lack the tools to torque the barrels properly - no vise insert/blocks or wrench.  Never done it before.

I am planning on running out to NRA in Fairfax Saturday AM to run a carbine and 1911; it'd be nice to get my A4 running.

To complicate matters, the A4:

1) Has a MATECH rear sight installed, and

2) I may be short the gas tube roll pin.

Other than that, it's ready to run, and I'm eager to test some Wolf/Prvi Partizan M193; you're welcome to help ;)

I live in Alexandria, work in Fairfax.

Can anyone assist?

I sent you an IM.

Figures Robb would be able to help out. He is the jack of all firearm trades. How did you go about getting such a great  job anyways Robb?

IM received and replied to - thanks!

I'll be back online about 2100 tonight. BT

Many thanks to GotM4 for your willingness to assist.  Nice to have met you!

No problem, it was good to meet and shoot with you as well.
