Capt Forest's Review of SIG SAUER Sig MCX Upper Receiver Assemebly, M-LOK
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!
