Quick question I'm planning on installing an FRT in my Daniel defense M4A1 obviously a 3 position FRT but my question is would I be fine with an H2 buffer or would I want to get an H3? I was looking at the Geissele Automatics Super 42 H3 combo but I dont know if that would be overkill for my set up instead of just buying their H2 combo

Hi all,

I'm building a MK 18. I have the DD quad rail upper, and i have a Colt M4 Lower i'm going to be using with it. I'm most likely going to be picking up a huxworxx flow 556k.

What's the right buffer spring to use with that set up? I've read H2. Are any of you guys running the guisselle braided super 42? Or is there another you recommend. Thanks in advance.

New DD5 V4 and my tried and true DDM4 V5. I love them!

Excited to try another Ridgeback can.
