need help picking parts for a 28" build

[mel]

im going to build a 28 inch barreled upper here soon but not sure on what handguard and upper reciver to get

what i do know is i want a side charging upper and atleast a 19 inch handguard
ive been finding extended and 19.25 handguards but they seem really cheap anyone have any suggestions on any decent ones that wont break the bank

and as far as side charging uppers i know bear creek has a few resonably priced ones along with bolt carriers but should i even bother with them
