Answer 1

If you have a 400$ budget you should just buy a new gun. Here are my suggestions.

Western Arms Gas M4: http://www.redwolfairsoft.com/redwolf/ai...

Bit over your suggested price, but great power and its gas!

G&P M16A3 M203: http://www.redwolfairsoft.com/redwolf/ai...

Very cool. Great deal. Great price.

If you want something besides an M16, I'll suggest these:

G&G L85A2: p://www.redwolfairsoft.com/redwolf/airso...

Classic Army AKS 74: http://www.redwolfairsoft.com/redwolf/ai...

STAR G36K: http://www.redwolfairsoft.com/redwolf/ai...

Its always fun to help  people with big budgets. You should also look for heavy machine guns like the M249 or M60. Check www.redwolfairsoft.com  

Answer 2

according to my husband.....You need to replace most of  the internals specifically the ones  stated  on your list. and get an 11.1 v battery for better ROF.
