    Used this upper to make a 22lr pistol via cmmg conversion kit. It’s a fairly standard budget upper but the handguard and the muzzle device are the cat’s meow in zombie fighting gear. Coolness factor is definitely there.
    I’ll likely apply some zombie gunskins wrap to take the coolness factor to critical mass.

    I bought this over a year ago.. and I must say THIS is an awesome product! Nice solid sturdy build. I put this on several lowers and fitment was not an issue.. 1.5 years, 850 rounds down range, and a pandemic later STILL no problems… wish I would have gotten more

    I stumbled onto this website during my search for a pistol upper. I found this cool little upper and decided to give it a go. Shipping was lightning quick and the quality of the upper rivaled much more expensive options. I put a quick magazine through it to check function and it went off without a hitch. I’d highly recommend this upper and this company and I look forward to using then in the future. Great job KM team.

    Thx, Mike

    Great looking and functioning, the only minus is that the flash suppressor comes in gloss black. A little sanding and rustoleum BBQ high temp spray matches perfect, but K&M should know and do this already !

    Upper Came In 3 Days Way Quicker Than I Expected . It Came With A Full Quad Rail Instead Of The Rail Slots Shown In The Picture. No Biggie! Added It To A Psa Lower With An Binary Trigger Ran Flawless. Next Im Getting The 300blkout To Have Twins 👍🏽

    I was on the waiting list when these came back. I ordered thursday morning and was lucky enough to receive it 30 minutes before I went to the range. I expected this to be high fun level for a few minutes, then enjoy shooting other stuff after having that man moment. Turns out, I enjoy shooting this more than my 11 inch barrel, and probably most else. For those worried about gas in the face, dont. My 11 inch with a regular brake is much worse, and it’s not too bad.
    As far as this company, thank you. Everything was ahead of schedule, from wait time for production up to delivery. It should be fairly simple, yet so many get it wrong. These guys are 5 star across the board in my book.

    Just plain fun. It does what it is meant to do, destroy stuff at close range. Be aware that this is a FAT upper, not slim and beautiful but gets the job done.
    Ordered one afternoon and shipped the next morning, arrived promptly.
    Thanks for the great service.

    Upper arrived early, and in reasonably discreet packaging. My woman noticed that the packing tape used was from “Jeffree Star Cosmetics” ???? Either way, upper looks tight, shoots nice and is a welcome addition to the collection.
