Thanks to John @ Retro Arms Works amazing pin and weld service and lightning fast turnaround, my modern day take on the XM177 in a dedicated 9mm caliber came out pretty amazing utilizing Spike's Tactical upper and lower components and RRA 10.5" chrome lined barrel.

Looks like fun OP.

JT is the man. I'm thinking of having him chop the bbl on my new (to me) Colt 9mm carbine.

I ended up turning my 9mm pistol into a XM-177 9mm clone a while back.

  • CMMG dedicated lower
  • Fulton Armory 604 type upper
  • Rock River 10.5" 9mm barrel
  • KAK fake XM177 moderator for 9mm
  • left over 6 position carbine stock

Here it is as originally built as a pistol
