What buffer tube do I need for AR-10?
Carbine buffers or buffers with weights that fall under the H2 or H3 category are most commonly what AR-10 owners should be using along with carbine length butt stocks. Rifle buffers are really only used with the A1/A2 style buttstocks due to the rifle buffer tube being longer.

Do I need a H2 buffer?
H2 Buffer (4.6-4.7 oz) These heavy buffers can be too heavy for some carbine applications, though they are often used. An H2 is likely too heavy for many mid-length systems, but this is not where they are most often desired. With the advent of AR-Pistols in recent years, shooters need heavy buffers to compensate.
Do I need a heavier buffer spring?
The Golden Rule. You should run the heaviest buffer that still allows your rifle to cycle completely and reliably, with the ammo of your choice. Have too little weight, and recoil will feel punchy. You’ll also wear out your receivers, buffer, and BCG quicker.
