So excited. My Sons of Liberty pistol lower is due tomorrow and will be paired with my 11.5" Craddock Precision upper. No more Shockwave/generic lower after this weekend. This will be running suppressed 95% of the time with a Dead Air Sandman-S.

I will be able to test fire it next weekend but want to order additional parts to have them on hand to test in real time. Ammo used will be IMI 556 55g, 69g, and 77g, FGMM 69g and 77g, Frontier 55g, 69g, and 75g and possibly Wolf Gold. But most likely sticking with 556 ammo for the time being.

Do you recommend I pick up Vltor A5H3 and A5H4 buffers and test those first before the H2? I will be tuning the gas by loading one round and rotating the gas key 1/2 rotation a time until the bolt doesn't lock back.

Also, do you suggest an LMT E Carrier with the Sionics bolt?

Upper:

  • 11.5" 1:8 Bartlein barrel with a carbine +1 length gas sytem and a .67 gas port
  • Vltor MUR
  • Superlative Arms AGB
  • SLR 10.7" Solo Lite handguard
  • Sionics NP3 BCG
  • Dead Air brake and Sandman-S


Lower:

  • SBA3 Brace
  • Vltor A5 RE with A5 H2
  • Geissele SD-E


I will post pics and report back on what ammo and buffers worked out best.

Thanks for all the help.
