I am selling my "Franken" build.
Lower is a Spikes color fill punisher lower with a Palmetto parts kit, UTG stock and tube, Spikes heavyweight buffer with normal spring.
Upper is Radical Firearms receiver, RF 1&8 twist barrel, RF BCG, RF adjustable gas block with pistol length gas tube, UTG Pro super slim rifle length hand guard, and comes with SWFA 30mm mount.
It has had about 300 hand loads through it both sub and super. I was getting MOA grouping, but I will admit I am not that great of shot. You could definitely tighten it up. Never have time to load 300blk and running out of room in the safe. $600 obo no trades at this time. Meet at Fort Worth cabelas or Grapevine Basspro. Must be legally able to buy firearm... LTC preferred.
