Extra Items are Included
Firstly, love them or hate them, it’s a nice Sig. There seems to be some confusion on how this conversion kit works, as well as exactly which items are included in this kit.

Poor condition
I received this upper today. The upper is dirty from use with scuffs, wear.

The best short 300 blackout Upper
Short and and MCX...what's not to like? Extremely reliable, awesome suppressor host, don't settle with a 9mm PCC when you can have a 300AAC in your backpack.

Best 300blk upper
This kit comes with everything you need to convert your lower and attach this upper.
Kit comes with a match grade trigger that is guaranteed to work with the upper. Some triggers are finicky with sigs internal buffer system.
This also comes with 2 different knuckle folders. one for a standard brace and one for a buffer tube. Overall its a great package for the price. Cant wait to strap a suppressor to it and go!
shipped quick and was well packaged.
OH ONE LAST THING, NO USELESS FORWARD ASSIST!

Rattler Upper
I picked up the 5" upper to set up my MCX as a Rattler. It has run flawlessly. I've run my suppressor on it without issue as well. I did switch the gas setting for subsonics when using my OSS can. Super happy with my purchase.
Pros:
- great gun
- cheaper than buying whole gun
Cons:
- still an expensive modification
Would recommend: Yes
