You will need a m4 cut upper for your build with a noveke bbl. it uses a basic bolt and carrier, you can just buy a new bolt since you already have a carrier and just switch them out. i usually set headspace with a case trimmed to the correct oal, you can get and use go nogo gagues tho. i suggest these parts as this is what i am build ing and all can be had from brownells

you will need to get a forward assist and dust cover assembley unless you dont want a dust cover. dpms offers a kit through brownells for their a2 upper which will work for around 50 bux. it comes with the rear sight assy also but you wont need it and can sell it or keep it if you have a a2 upper already, also comes with a charging handle :D

i am goning to use a yhm handguard/ff tube and you can get them for around 125 or so. that is the cheapest m4 upper i have found fyi. oh and you will pefer a rifle leagth ff tube if shooting off a bipod. yhm makes a adapter for that too

New upper recievers with M4 feedramps are available at BravoCompany for $96.

New bolts and carriers are also available from the above company. Shopping around helps. I've found BCM prices to be better than Brownells on some items, and Brownells better on others.

If you can use .223 brass for .300 Whisper does that mean you use a standard AR-15 .223 bolt?

Yes - that's one of the nice things about this caliber. You can use all standard AR15/M16 parts except the barrel.
