Description

OBO
Sig MCX rattler upper receiver with the trip bar already installed so it’s ready to rock with FRTs has a small scratch on the handguard you can see in 1st pic other than that it’s clean.
This was a solid backpack gun for a while but looking to switch it up to 300blk.
5.5” barrel 556. These are pretty hard to get your hands on now

Would consider straight trade for 300 blk spear lt upper
Or M&P 2.0 spec series 6
Nothing else so please don’t ask
