| I have a QC Colt lower inbound to change things up on an older CMMG 9mm that I own. I'm looking at changing to either a 5" or 7" barrel in the near future to most likely run suppressed, Blitzkrieg offers two buffer/spring combo's, the "Blitzkrieg 9mm Hydraulic Buffer/Spring Combo - Pistol/SBR " and the " AR-15 9mm AKTIVE Buffer/Spring Combo - PISTOL/SBR". I plan on giving one of the two a try and just from casual reading on their site I'm leaning toward the Hydraulic version, is there a preference on either one especially with a suppressor? |
| I have both Aktive & Blitz Hydro, I love them both, butt the nod goes to the Hydro, smoothest 9mm buffer I've ever used , cuts recoil impulse to nada, Also MGI has a mechanical buffer that works great as well. I run the active and Blitz with 308 Sprinco carbine springs(orange marked) one with 16" barrel pre ban colt, the other my own build with 11" barrel. I shoot 95gr-158gr loads including +p and +p+. No failures and no need to change springs for different loads. |

Thanks for the response, nice to get input from someone that has experience with both. Time to drop some coin and I can always play with the springs if needed. Running suppressed you may need to I'm not sure since I don't have a suppressor yet, but so far those set-ups have worked with everything I've used even HP's. good luck with it. |
