This is what I'll be ordering today

Midwest Industries T12 Quad Rail
Vltor Mur-1a Upper Receiver
YHM Low Pro Gas-Block w/ set screws
BCM Full Auto BCG
BCM Carbine Gas Tube
BCM Large Charging Handle
Barrel - EDIT - 9/27/11 - I ended up ordering a YHM 14.5" w/ YHM 5C2 FH Pinned and Chrome lined Barrel

Lower - I have 2 lowers available but this is going on my SBR when my forms return.

Do I need screws, bolts or pins? Also I shouldn't have any clearance issues with the MI T12 rail and my YHM low pro gas block?

Flash Rider will probably just be an A2 for now or a Smith Vortex

Gas Tube Roll Pin - Will my YHM Low Pro Gas block come with a roll pin?

Barrel Nut, AFAIK it should be included with my Midwest Industries T12 rail? Can anyone confirm?

Barrel nut wrench - I had a buddy who has all the tools to assemble.

I don't remember offhand but I don't think my YHM low-profile gas block came with a roll pin. what about your lower receiver - parts kit, stock, etc.?

I heard some people have gotten roll pins with their YHM GB's and some haven't. I sent an email to BCM regarding it. I already have a complete lower from another rifle I'll be using.

Only other things I can think of would be the forward assist and ejection port cover assemblies.

Most gas tubes come with the roll pin. Mine from Spikes did.

Both gas tubes I've ordered did not come with a roll pin, neither have the gas blocks. If your tube doesn't come with a roll pin I can drop my extra one into an envelope and send it your way.

Thanks, I'll keep you posted. I got an email back from BCM and they said their gas tubes come with a roll pin, also the MI T12 comes with a barrel nut.

I take it you already have the lower complete?  Otherwise, lower receiver, LPK and stock kit.

I have a Bushmaster lower w/ a Vltor mod stock that I'm SBR'ing. Just waiting for my forms to get approved.

Are you going to use the Midwest T12 rail with the 10.5 SBR?

Yes I am, I wanted to hide some of my YHM suppressor under the rail.

No mention of lower, lower parts (fire control group for your auto BCG, buffer tube, buffer, spring and all lower parts).

Are you buying a fully assembled lower?

I have 2 complete lowers and one is pending for SBR.

I exchanged the barrel for a 16" non pinned barrel. Thanks for the help and all the tips for installation.
