What is the standard buffer weight for an AR-15?

AR-15 buffers comes in a few different weights and lengths. A standard carbine buffer should weigh 2.9 ounces. Moving up in weight, an H buffer, or Heavy Buffer, is nearly a full ounce heavier at 3.8 ounces. The H2 buffer has a slight variance depending on the manufacturer, but should be 4.6 to 4.7 ounces.

What does a heavy buffer spring do?

If you get a buffer/spring combination that is too heavy the rifle won’t be able to push the spring back and pick up a fresh round. If you get a buffer/spring combination that is too light, the bolt carrier might move too fast and out run the next round coming up from the mag.

How heavy should a 9mm buffer be?

What does a heavier buffer weight do?

H1 Buffer Weight | ~3.8 ounces The Heavy buffer weight, or simply “H”, is commonly referred to as the diagnostic buffer. It’s the buffer weight many shooters turn to if their rifle is over-gassed, felt recoil is too sharp, or the bolt unlocks too soon because the buffer’s too light.

Do I need a heavier buffer?

If it’s a service gun, leave it alone. If it’s over-gassed, and you don’t have an adjustable gas block, adding a heavier buffer can noticeably reduce felt recoil. If you do have an adjustable gas system, reducing buffer weight can do wonderful things.

Is H2 buffer too heavy?

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. A standard carbine buffer is far too light and will likely result in violent cycling of the action.

What happens if AR buffer is too heavy?

The heavier the buffer the longer it takes to move. It will also slow down quicker and smooth out the recoil. Going with too heavy a buffer though can cause the rifle to short stroke (i.e not fully cycle, which will lead to inconsistent extraction and ejection).
