I waited a year for this. Its finally hear to reside with my AR15 collection. I did a lot of reading up on it, so my hopes were high and my expectations were low. SIG always manages to generate controversy and roll out products that are............not quite ready. This is their 3rd generation of the MCX, so I was hoping they had it figured out. Then I read about hand guard shift and barrel movement. It had me a little worried, and it was the first thing I checked. I was very relieved to find mine was tight and straight. These are just some initial observations. I will try to update with a range report.
Complaints:
Plastic Forward assist/shell deflector housing.
Trigger kinda sucks. Has the same rolling feel that my 556 has.
Off side bolt release is a tiny lever. It does not exude confidance. It may be robust, but does not feel like it.
Factory skeleton stock is wayyyyy to short. First thing I replaced.
Tapered barrel at threads. SIG sells a taper cap to use standard muzzle devices. $12.00 plus shipping.
On line owners manual. That will come in real handy if im shooting in an area with no cell service. Which is often. Yes, I read them occasionally.
Compliments:
Handguard is solid and comfortable
Folding stock.
Top rail length
Gas piston
Uses AR15 triggers, Stocks, Grips
I ordered the Collapsible stock from SIG. They sure are proud of them, but it looks and works great. Also added MBUS gen 3 back up sights and a Trijicon MRO. The little handstop is from Arisaka. As soon as I have time to modify my BEVBLOCK to fit the barrel extension, I have a Hypertap muzzle break for the end of the barrel.
