I'm wanting to do a build ( and on limited budget) I'm looking at getting one of these http://faxonfirearms.com/16-gunner-big-bore-450-bushmaster-nitride/
and swapping it into a upper I have a 24" WOA barrel in now.

I know I'll need a bolt and some mags and a flash hider ( which everyone seems to be out of stock on) anything else I'm missing?

Also we need some 450 info in the variants sticky

Ejection port modification, too.

Let us know how it shoots!

Just assembled my 450 the other day. 18” Tromix ultra lite barrel with Saturn Big Bore Upper.  Need to get an optic in the 1-6x range and muzzle break.  It took a lot of sale watching, backorder wait lists and a little luck to gather all my parts over 6 months, but I’ve got $600 in it so far, including the lower.

I like the Ruger 450 brake, it’s about $100.

As other have said you will need to enlarge the ejection port, or buy a upper with this work already done. I think Anderson Arms makes the cheapest big bore upper. I used a Aero Precision for mine. I would skip the flash hider, and look at a muzzle brake.
