The CMMG MK 57 is an AR pistol shooting 5.7×28 the same caliber as the FN P90 bullpup and Five Seven pistol. The result is a low recoil Pistol Caliber carbine (pcc) that is fun to shoot. In today’s video we are going to do a pistol caliber carbine competition between the MK 57 and the p-90.

Perpendicular…..
god he has so much ammo
Regarding the extra weight: ps90 has a 5 inch longer Barrel, longer 50-round magazine, heavy dinosaur site. All that into consideration it's not too bad.
Regarding ps90 pistol possibilities: I've wondered for years why no one makes it a pistol configuration. Theoretically it's easier to shoot one-handed like a pistol then any of the other AR conversions out there.
Theoretically all they would have to do is slide in a different trigger group cover that was not contoured to the shoulder and then they could put a 10 inch barrel in it and call it a pistol.
It would be that simple and I don't understand why no one has done it.
I wonder why that P90 choked up so much, every thing else I’ve seen of them show reliability. Probably the upkeep is not good on it.
How did you get the “restricted law enforcement” markings on the CMMG lower?
You forgot to mention the trigger. Who has the better trigger?
So I looked up those m16 full auto rifles and there 50k. How much was that cmmg MK57 pistol lower with full auto? How much was that p90 in full auto? Ballpark me? Do you have a import license? I would love to have that capability. Great video one of a kind actually.
The P90 is definitely a slicker package for actual PDW purposes (assuming it was reliable)
The AR definitely wins in ergos.
Full automatic p90 amazing! What state is this?
I’ll take the banshee
The factory sight might not be the best on the P90 but any other optic looks stupid and out of place.
Too many ads
If your using American Eagle 5.7 I think it lacks the case coating that FN puts on their ammo. It’s the only stuff that’s caused my ps90 to choke.
Hmmmm…. 50 rounds vs.20. No debate.
Also, do you really think all P90’s choke? Think about it.
Omg all that 57 ammo fuuuuuuu lol it's so hard to find and so expensive!!
I’ve had one of the mk 57s since they came out. I love that gun. The p90 is just to awkward.
Was/were the P90 mags old or worn out? They looked like they worked ok until nearing the end of the mags. I’ve never seen one in person so I’m no fanboy of them. The design is just cool.
What is your opinion as to why guns like the PS90,FS200,SCAR,MCX,ACR, ….ETC sales dont compete with the AR platform rifles? I have my opinion, but I want to know what you/your followers think. Price? repair cost? Commonality? adaptability? Stupidity? Im an engineer and seek innovation in firearms tech, but it seems nothing has been able to trump the AR platform for any caliber.
Owning a PS90 and an AR-15 set up with a 605 upper, the PS90 is a deceptively chonky boi. It is balanced and fits nicely in your hands, but there is no denying that there is a lot of weight in that small package.
I wish they would make a 9mm P90.
That Banshee looks so good. Rip stock is ba as well
That's a $1.05 a round there buddy, an that's the cheap shit too lol
Thank you
Over 2 years ago I started building AR’s and I found you guys and have not missed a show!!! Love it👍👍👍👍👍
7:54 was super cringey. Also I'm guessing no one ever cared to clean the chamber of the P90 out…
The P90 makes me think of GoldenEye for the N64 every time
Whatd you guys do to change the rate of fire??? Buffer/springs????
P90 all the way too much of a stargate sg1 fan to choose the other
This is the first time that I've heard of any reliability problems with the P90. I've rented several over the years too.
Unrelated question, what’s up with your beard? Did you fuck up when trimming it, or did something else happen?
CMMG needs to develop piston driven PCCs now that this arm brace nonsense is going on. That would put them on top off the PCC market
Due to overall effective barrel length, you really can’t compare intelligently.
My PS90 has been my goto coyote gun for years, and has taken well over 100 of them at ranges from 25-200yds
Wife's PS90 chokes on American Eagle 5.7×28 no issues with the blue tip FN stuff.
I can't speak for the full auto version of course but I have 3,000 ish rounds though my PS90 and have had no malfunctions or reliability issues. Just in case anyone was trying to decide between the two.
This video was not cheap to make. 5.7 ammo is expensive and hard to find!!!
We should all be able to buy both of these babies. Fuck the ATF.
