These seem like the hot guns right now but I'm struggling to understand why? They're basically a piston AR and a 9mm AR. Am I the only one who is not impressed especially for the $1500+ price tag?

Anyone can set-up an AR to do 5.56/300blk or 9mm and have a floated barrel for half the price.
 
I've kinda wondered that myself. I've heard the price quoted at $2200 for a decked out factory 9mm pistol.
Maybe worthwhile if it was select fire.

I would assume if your looking at 9mm PCC's. 556/300blk isnt on your checklist.
The price doesnt seem out of line for the other 9mm PCC's out there.
 
The MPX is priced in the MP5 "clone" range, and personally I don't find any complaints for having more options which is what both the MCX and MPX provide. Those who want something different will find the price worthwhile.
 
SIG is the new "HK." They have been able to position themselves on the market well. Their product line has depth, and the models come in a lengthy variety of sub models.

There is also the New! factor, and SIG does have the provenance of being military issue in more than one first tier government, including ours. Those departments and shooters who aren't saddled with the Beretta M9 can elect to carry SIG's and they do every time.

If you want to have something "better" than another boring run of the mill AR, you look elsewhere in the current marketplace, and SIG delivers to that buyer with US production based pricing. Poor HK has to get a permit from the German government to do anything these days and still suffers from the exchange rate. SIG didn't miss the boat by having the American plant independent of the Euro market. They are at the beginning of what appears to be their heyday. HK is however in serious decline and it's not going well. That has a lot to do with it from the perspective of their shared demographic buyer.

We aren't talking commodity guns in this market segment.
 
The MCX is innovative as its one of the only AR -ish platform guns that can be fired reliably with the stock folded . That and it allows for quick barrel/caliber changes 300/.223 . There is also a much improved lockup to their thread on silencers which I have one of and it is a most excellent unit.

Ive been trying to get a MCX SBR for going on a year with no word on when SIG is going to actually release them. They tend to announce a lot of stuff at shot shows then drag their feet on actually releasing items for sale.

9mm AR's arent in the same league as the MPX. The MPX features a delayed bolt lockup that greatly reduces the "bark" coming out of the ejection port when used with a silencer and reduces felt recoil. Ive had some 9mm AR's that sounded like total hell when fired with a silencer. Big difference in how a delayed release semi works and how a direct blowback gun works. The direct blowback AR-15 might as well be a high point carbine. The MPX does everything an MP5 does without destroying the brass. Its a good gun.

The SIG is actually purpose built as a PCC, not adapted with a crude blowback design like the AR using Uzi or pistol mags. I wish they were closer to $1000 but I do plan on picking one up. Or the Scorpion.
 
SIG makes a good pistol, but I don't trust their US production rifles with as many of them as they've managed to screw up, such as the 556R and 556xi.
 
The Sig MPX is a military grade MP5 alternative specifically designed with low recoil and suppressor use in mind.

Most 9mm AR's are cobbled together blowback plinkers. If you compare it to a Colt 6450 or 6951, or to the Turkish/Pakistani licensed MP5 copies, it's not unreasonable.

Piston AR15's are old hat. Piston AR15's done well are a different story. The MCX is a reasonable alternative to the HK416, which is saying a lot.
