My go-to
by Jordan Krassenstein
I remember thinking like a week before these were released why no one makes a 7075 buffer body, like wouldn’t you want the stronger material taking the impact of the steel bcg? Then boom, Primary/Expo arms comes out with them and cheaper than most others’ presumably 6061 buffers. Bought 5 so far, and adding a couple more. Also, of note is that they’re easier to identify because the gold/tan color from clear anodizing the 7075 (a la Arisaka mounts), and also engraved. Just get them, but wait until I buy a couple more. :)
Good quality

My son built me my first AR using this buffer. He is a stickler for details, and said that this was the buffer I needed for my particular build. He said the buffer ad great fitment, and would work great. Haven't fired the weapon yet, but anticipate it functioning perfectly.
Well it is a buffer.

Well made and weight is just what it is to be so. Great!
End of the day it is a buffer.
