|I received the second and third generation
blackjack buffers in a unmarked manila envelope. Which
is always a good thing because it keeps nosey mailmen
from knowing you own some kind of firearm. The buffers
were well packed in bubble wrap preventing the buffers
from being damaged in the mail.
Once removed from the bubble wrap the buffer comes
in its own sealed baggy with instructions for installation.
Luckily these things are so easy to install any Joe
who can take the rifle apart can do it. It took my less
then a minute to install.
The first set I received was a series of 2nd Generation
green colored buffers that were considered "medium"
duty. A balance between durability and "shock"
absorption between parts. These buffers are designed
to protect from unnecessary wear caused by the extreme
force of the recoiling parts in your rifle.
I put over 2,500 rounds on them, 800 of which were
bumped (mostly at the Calvert shoot)...they show little
wear and definitely felt like they reduced vibration.
Unlike most buffers, these did not cause any short cycling
in my rifle.
The next set of buffers I received were the generation
3 buffers, according to Randy these have been fully
refined into two distinct types. A green version, which
is the "medium" duty version and is the same
as the black ones I have testing. And a black "extreme
duty" version that is really hard. This black version
sacrifices vibration reduction for reliability and protection.
I have only put 400 rounds on this buffer but it looks
like it will stand up to at least 5,000 rounds our more
of full auto fire. With the Green and Black buffers
the only ones being produced now you have to choices.
Basically the choice is based on how/what you shoot:
For example, each type of buffer has a trade off:
Medium Duty Buffer:
Less felt vibrations/noise/ from recoil
Absorbs some stress (energy) associated with the recoil
Lifetime is estimated at 7,000-10,000 rounds
Some vibrations/noise/ from recoil still felt
Absorbs most stress (energy) associated with the recoil
Lifetime is estimated at 12,000+
As you can determine from the above information, the
softer medium buffer absorbs more of the
felt vibrations and noise from the recoil then the harder
one. This is because the medium buffer absorbs more
of the energy as a result from the recoil operation.
So why would you want to go with a hard buffer over
one that absorbs more energy?
Well it is the lifetime of the buffer; since the medium
buffer is softer it starts to deteriorate sooner then
the harder one. Depending on how much, and how often
you shoot, should influence your decision between a
medium or hard buffer. For example if you are one of
the lucky few who own a Class III AK, or one whom expends
500 rounds or more weekly in you AK, then the hard buffer
would probably be a better choice because of the increased
frequency of stress placed on the buffer. Not to mention
the increased amount of ammo that can be cycled through
in a day at the range, thus the lifetime of the buffer
becomes a concern.
