Easier, cheaper, better, etc to build your own with pieces rather than buy one?

Perhaps easier for guys on a budget, as the expense can be portioned out over time by grabbing a part here and there when on sale.

For similar quality parts, buying or building are similar costs.

Pro with building is you get exactly what you want; Con is, it's re-sale value is generally not as high as a built upper, by a recognized company/builder, unless you get a buyer that is knowledgeable & you haven't screwed anything up.

I have put together my own lower and i have changed my oil and brakes and spark plugs. Lol is it more complex than those?

No, as long as you know all that you understand about doing it. LOL

Uppers are easier to put together than lowers. Make sure you have a torque wrench for the barrel nut and a receiver rod or something similar to hold the barrel in place as you torque it down.

Gas block and tube...? Those seem more complicated. I hear guys talking overgassed and undergassed etc

Assembling a AR15/10 upper is no more mechanically complex than assembling a lower for the same. You WILL need the proper wrench for the barrel nut, a decent sized bench vice, and a receiver block to keep from damaging/twisting the upper receiver in the vice, while torquing the barrel nut down.

@auk1124; many thanx for the Nosler chart, valuable info.

Mine are really screwed up, kicks them out between 7:30 and 8:00

Ya gotta quit holding that gun upside down

You are welcome!

I have the tools to do both an upper and lower. Both are easy peasy.
