Most Helpful Positive Review PCC AR Buffer
I was building a 9mm AR and wanted to use the correct heavy buffer to make it last. I found this one at Optics Planet. Ordering was super easy, and it arrived in just a few days. Thanks for having such good customer service. I’ve ordered other various items from Optics Planet and have never been disappointed.

Binds when spring is fully compressed.

by Necrowpharaoh, Verified Owner from OR, United States Written on January 20, 2022
Spring gets bound in the buffer tube. I could have just gotten a bad one, but I'll stick with aeroprecision in the future, I think. The locking nut is wider then any of my others as well and doesn't spin quite as smoothly. I matched it with a luth-ar stock on a 9mm carbine and the stock is about the same quality. Sometimes functional with heavy faults.
Pros:
  • Cost effective if you get a good set
Cons:
  • Spring binds in buffer tube
Best Used for:
  • Budget build that won't be relied on
Would recommend: No

Great 9mm buffer!

by Jeff, Verified Owner from NH, United States Written on February 21, 2021
Ordered and ran this buffer in my PCC all last season and it kept up with all the expensive carbines! Flawless in my Spikes lower with PSA upper. It absolute fire paired with a Hiperfire eclipse trigger!
