Rookie question but need help -- :) "Buffer, tube, and spring not included."

hi guys,

building my first complete ar15. just ordered the long awaited magpul ACS and know that the buffer, tube, and spring are not included.

my quick q’s are:

i plan to get spike’s ST-T2 heavy buffer
Q1 - [any recommended mil-spec tube?]
Q2 - [where can you get just the stock spring?]

thanks guys!

bravocompanyusa.com or gandrtactical.com will have what you need.

Why go with such a heavy buffer? Save your money and get an H buffer from G&R or Bravocompanyusa.

Remember that you’ll need a castle nut and endplate as well.
