Buy high quality punches in general I recommend starret for the none roll pin type.

Buy a barrel vise The viper is excellent. http://shop.brownells.com/gunsmith-tools-supplies/general-gunsmith-tools/vises-accessories/barrel-vises/barrel-vise-sku100013367-58959-123515.aspx?cm_mmc=PPC-_-Itwine-_-Google-_-100-013-367&gclid=CjwKEAiAjIbBBRCitNvJ1o257WESJADpoUt0SFb6lBg-x3fdGfsdwZDF0XGfx8AMg43bfFV-DRafuhoCBhjw_wcB

Never hold a weapon by anything other than the barrel when applying 60+ foot pounds of torque if you can help it.
That all off the top of my head for now.

High quality punches make all the difference. Must be high quality tool steel. Grace USA - Steel Roll Spring Punch Set - RS7 - https://www.amazon.com/dp/B007WADKN0/ref=cm_sw_r_cp_apa_1Bf5yb210M8D0 get a cheap set of starter punches also. Quality on these is a non issue really.

First buy some pin punches, like Grace or Tekton (avoid going cheap, they always break).

Then of course a proper hammer

Then some starter punches

Then some finishing punches (I know they say starter but they're better for finishing)

Yes, it costs money, but they pay for themselves. Also you don't have to dick around with taping things off as much if you have proper tools. The brass punches and the pin capturing starter punches help IMMENSELY in this area.

I used these long roll pin punches:

and this bench block so I had room to punch the pins the whole way.

Wheeler stuff is okay for one or two builds, but if you plan on tools lasting I would buy them separately. I bought wheeler initially and now have 8 ar's and have re-purchased all tools because the wheeler stuff doesn't last. I like the tapco intrafuse wrench because it has the necessary bottle opener, roll pin punches, plastic/metal hammer, allen keys, PRI upper block, pro mag lower block and if you have a free float handguard I use this spanner.



Edit: On my armalite ar-10t, the FF handguard requires a strap wrench so keep that in mind if you plan to deal with those.

I'd recommend spending the money on a set of Grace USA punches. Bought mine from Amazon and I absolutely love them. I bought these. I also bought this set of Grace roll spring holders. Very useful for starting roll pins. A decent hammer (I have a dedicated brass mallet and a dedicated nylon mallet), and a [bench block]https://www.amazon.com/Wheeler-60981-Universal-Bench-Block/dp/B0047WKF84) if you like things to be easy.

I also have a needle file set (don't remember the brand, but they were like $20 for 6-8 of them). For sanding on the internals I generally just use wet/dry sandpaper. Usually start with around 200-grit, and end with 800-grit. For polishing, Mothers Mag and Aluminum Polish and a white t-shirt. With enough time, it will give a nice mirror finish and be as smooth as ice.
