Up for sale is a Sig Sauer MCX Rattler 5.5" 300 Black Out complete upper. 626 flawless rounds downrange, just moving in a different direction. Comes with the original muzzle device (not currently installed, but I can install it or just include it if you plan to run it suppressed). Buyer's choice for handguards. You can select the original Sig Sauer short handguard or a Midwest Industries 10" Suppressor compatible MLOK handguard. For $125 extra you can have both. Some normal marks from mounting accessories on the Midwest Industries rail as that is the one I utilized.
$1600 $1500 $1400
$1300 shipped to the continental USA for this complete upper with (1) rail or
$1725 $1625 $1525
$1425 for this complete upper with both rails. Also, I added the forward assist as these Rattlers don't come with that. If you want it without I can remove the forward assist and replace with the shell deflector that has no forward assist. A little dirty, I will wipe it down, but don't plan to clean it to new condition (new owner can do that). This is a nice compact package. I will include the owner's manual and Sig Duo match trigger as well. If this listing is up, I still have it. It is cross listed. PayPal FF (no comments of anything firearm related), Venmo, or USPS money order. Email from this website is the best, as I don't get notifications of IM's. Thanks.
