Is this buffer good for frt trigger

A
Answered by Roge, member, from NC, United States, on March 07, 2025

If your barrel is under 14” I’d definitely go with a H3, I have a 10.5” upper and my H2 will actually run, but they guys at Delta Team Tactical specifically told me they’d recommend a H3 buffer. I’m also going to try out a springco “enhanced” power buffer spring to help as well.

Q
Jonathan Vargas, guest, from FL, United States, asked on January 07, 2022

Would this work with a 8in 300 blackout pistol build?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on January 13, 2022

Yes. The Aero Precision AR15 Buffer I would recommend is the H3. MPN: APRH100953C
For 300 blackout, especially with a short barrel, you want to go heavier on your buffer to help minimize and control the recoil.

What weight would you recommend for a 224 valkyrie

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on January 13, 2022

The Aero Precision AR15 Buffer I would recommend is an H2 buffer MPN:APRH100284C
H1 and H2 buffers are typically used in 5.56 builds and seem to be the most reliable buffers to help the firearm function correctly. It similar with 224 Valkyrie. If you have a barrel length above 11.5 inches I would say to use the H2. If it is smaller that 11.5 inches, then go with the H3.
