BNIB 223/556 calx barrel conversion kit for Sig Sauer Rattler

[mjpgolf1]

Attachment 67762Up for sale is a brand new in the box never opened factory Sig Sauer .556 calx conversion kit for the Sig Sauer MCX Rattler. This is the 5.5” barrel and piston assembly that easily swaps out with pulling the front pivot pin, unscrewing 2 t25 torx screws and pulling the factory 300blk barrel assembly out and replacing with this. It’s now been discontinued by Sig so who knows how the availability will be on these moving forward. Allows you to shoot the less expensive 223/556 while using the same platform. Awesome setup. I haven’t opened the box so no pics to post as it’s just a brown cardboard plain box that these come in. Please let me know if you have any questions. I ship within 2 business days of receiving payment. I accept PayPal or Venmo only. Feel free to reach me directly at 330-201-0199….cell, mjpbmwe46@yahoo.com, or just thru PM here.
