About SIG Sauer MCX
Unlike every other firearm on the market, the SIG MCX was built for optimum performance with the 300BLK cartridge and a suppressor. The outcome is a firearm with superior suppression capability and enhanced reliability with both supersonic and subsonic loads A two-position gas block makes the transition from subsonic to supersonic as fast as flipping the lever. Changing between 300BLK and 5.56 NATO is as simple as swapping barrels and magazines in a matter of minutes. Converting to 7.62x39mm simply requires barrel, magazine, as well as an additional bolt change. Each SIG MCX features an aluminum KeyMod handguard, AR-style lower controls and utilizes polymer magazines. A revolutionary recoil system does not require a buffer tube, allowing for side-folding stocks. A picatinny top rail allows for the mounting of lights or optics. The aluminum forend allows for rail sections to be added where they are needed, permitting the attachment of accessories. The lower receiver offers familiar AR-style controls. Completely ambidextrous controls include the safety, magazine release and charging handle. Specifications: Aluminum KeyMod handguard Carbon Steel Barrel Ambidextrous Controls Folding and Collapsing 3-Position Stock: To make the package as compact as possible, the MCX PATROL is equipped with a folding and collapsible 3-position stock.

I have 300 rounds using many different brands and grains of supersonic & subsonic 300 Blackout AAC. This firearm is only happy with a sound suppression attached. With that said: Supersonic or subsonic.....I have found that using a holographic EoTech 300 B

So far in the 500 rounds I've put through it, it's been quite a wonderful rifle to shoot. I slapped some irons on her and put a little hoppes on the inside and let it rip. It was all in the span of a couple hours that put those rounds through it and I'm g

The MCX is a wonderful well thought through rifle. I find the gun very accurate when fitted with sig optics and so far feeds well with no failure to feeds after a couple of hundred rounds with different brands on ammunition. I like the internal piston des

I bought the MCX with the 300 barrel and the 556. The only thing I should point out is that the bolt carrier is coated in nickel boron which is great but before I even fired the rifle the coating was chipping off. I called Sig and they told me to send it

I imagine these are good. I don't see any reviews yet and older models are out of stock. I can't see Buds selling guns that have an active recall on them either. But only way to confirm is if serial# ends in 25000 or higher. Buds are the only ones that ca
