What tools do I really need to assemble a lower?

Well, I've got all my parts ordered to finish out my AR build. BCM complete upper which I'm gonna mate to a DIY lower using an Anderson receiver, Magpul CTR stock kit, and CMMG lpk.

Anyway, what tools do I really need here? I'm not gonna be building a bunch of ARs, so I don't want to waste money on tools. I'm 90 bucks under my budget and at this point only wanna get the truly necessary stuff.

I've got:

• vise
• elec tape and masking tape
• computer/microdevice-sized screwdriver/hexdriver set
• small hammer
• other typical male household tools

Here's the tools it looks like I almost certainly need but dont have:

• roll pin punch set
• anti-sieze compound

Other tools I see mentioned but not sure I need:

• dry lube for the stock/tube?
• lowend block for vise? I heard you can just use elec tape on the sides of the vise (and plenty of masking on the lower), and it'll hold up well enough for a basic lower build.
• armorer's wrench -- is this really necessary or is there a cheaper way? Bass Pro has one for $50 that includes a torque-measuring device, but I see some cheap options Amazon for under 25.
