What is a Buffer?
The buffer is a small piece that is located inside the buffer tube of numerous rifles. Along with the buffer itself is the buffer spring that supports it and gives it the capability to shift around. The buffer tube is attached to stocks. However, in the case of a 9mm AR-15, most of these buffer tubes will be devoid of a stock since AR-15 pistols do not need them.
The purpose of the buffer is to make the firing aptitude of your pistol more effective. Without it, it’s just another single shot machine that is chunky and not as effective. The buffer does its part in absorbing a good deal of recoil that can allow for better resistance on your end.
Without this buffer, the energy will be a bit too much to handle for the spring located inside and can break apart and hence making BGC cycling much more difficult.
The Criteria: What Makes a Great 9mm AR Buffer?
There are some things that will make a buffer stand out a lot better when pitted against those that are useless and crappy in quality. Knowing what makes a great buffer can help you make that discrepancy between which is better than the other. Here are a few things on what to look for while searching for a 9mm AR buffer:
Most of the 9mm buffers will be created from rubber. This material will quite likely be your best bet if you wish to absorb and resist a great amount of recoil impulse and the shock that comes with the 9mm carbine buffer. This will also help make the 9mm buffer spring take on a lot more while still being able to shift. If you are looking for a 9mm buffer spring, steel may be your best options here since it is a much tougher metal material for situations like a bolt catch pistol caliber buffer 9mm carbine which require heavier buffer.
If you are a budget shopper, the price tag will obviously be a lot more important for you. Especially when you are looking for the best 9mm buffer weight that you can afford and is made of stainless steel. As soon as you find something that’s high in quality and fits your budget, odds are, you may have found a 9mm winner. As a rule: never settle for low-priced 9mm AR buffers made of stainless steel. A cheap price tag can sometimes mean poor 9mm quality.
Will it Fit Your 9mm Buffer Tube?
Not all 9mm AR buffers will be created equal. That being said, it is important to get a solid idea of whether or not it will fit your 9mm stainless steel buffer tube in particular. Consider measuring the buffer tube itself while you are looking for a suitable replacement 9mm buffer. If you do not have one, you may want to consider getting yourself a stainless steel buffer tube along with the assembly itself. It should also be noted that some stainless steel 9mm AR 15 buffer tubes will come with an assembly with it.
Know Your Gas System
You will either have a carbine gas system or a pistol gas system. No buffers are created equal. Some of them are made for pistol length gas systems, but cannot take on anything as powerful as a carbine. At the same time, a 9mm AR 15 buffer made for a carbine or stainless steel will not work effectively with ARs that are equipped with a pistol length gas system.
Make Sure You Have All The Right Parts
This is important. A 9mm buffer AR 15 tube made of stainless steel will not be the same without a 9mm buffer AR 15 and the spring. The 9mm buffer AR 15 will not work if it’s in the confines of a 9mm buffer tube. In summary, make sure that you have the right parts that can be accumulated and put together in the rifle itself.
