Anything heavier than an H3 carbine buffer?

[Clint]

Just for completeness, there are also the stainless body A5 buffers.

Weights for the Stainless A5 buffers

A5SH0: 6.35oz
A5SH1: 7.19oz
A5SH2: 7.97oz
A5SH3: 8.81oz
A5SH4: 9.60oz

These are most useful for blowback PCC applications and generally way too heavy for normal DI uses.


An over sized gas port or a high restriction suppressor can add enough gas drive to over power any reasonable heavy buffer.

As mentioned before, if a carbine is way over gassed, that should be addressed first before changing buffers.

If you need a buffer that heavy, you gun is overgassed.
I make all my guns run on a H buffer.
There are several products on the market that can enable you to acheive that.
Putting in a heavier buffer is not the answer.

This right here.

Also, quality barrels with proper gas ports run great with H1 buffers.

Why on God's earth would you want this? An H3 is already miserable. And screw heavybuffers.com. Those dolts make solid buffers that bounce like ping pongs. Anyone that clueless shouldn't be in the gun biz!

9mm blow-back, for one.

9mm blow-back, for one.

Lord. I'd forgotten about those nightmares. Twice the recoil with a fraction of the muzzle energy. I remember those Cav Arms plastic lowers used to break when goobers converted them to 9mm.

Doesn't cmmg have something like an 8oz with their 10mm?
