I'm looking for a side cocking upper for my M10/45 and my M11/9. I've seen the ones listed at us machine guns is there anyone else hurt you recommend. Also looking for a KMP grip for the M10.

MPA makes them but they are always out of stock and I don't know if they take back orders.

A board member here had the process for getting one.
Was pretty straight forward.

I'd like to pick up a pair for my two guns one day also.

Not trying to rip on usmachinegun uppers but they are all but out of spec. We have had three come in for repair and had to be tried and squared. Just to get the bolt to slide in and out? Imho. Mpa does NOT make usmachineguns M10 uppers, I don't know who does? But yes call Lisa Foss at Mpa. Sure she could hook you up. Good luck.

Mine was missing the bearing and the charging handle
Flipped around from day 1
Also jammed up a lot

I sent it to Sam practical solutions and he added a spring and found they used a Mac 9 part in my Mac 10 upper

Bottom line. Buy one from Sam. I paid hundreds more for him to fix mine from the other guy

I also recommend Sam's products. I have the .380 Side Cocking Upper Receiver and it did not disappoint. No modifications needed and excellent performance. Coupled with the In Lead We Trust Shorty .380 barrel and later the ILWT 3-Lug .380 barrel, there were no malfunctions (used a tuned ZMAG). I thought there would be a period of breaking in, but the combination worked perfectly right out of the box.

For your M10:

https://macmachineguns.com/?product=m10-side-cocking-upper-receiver-with-barrel

For your M11/9:

https://macmachineguns.com/?product=m119-side-cocking-upper-receiver-2

Based on the craftsmanship and design, I'm very glad that I bought one.

My USMG M11/9 upper works great, once I adjusted the feed ramp a touch. He's got a ton of other stuff on his site too so I'm glad he's around as a vendor. I've also got his vertical foregrip, speed cube, and buffers. I've had questions via email and he replied. Not much more I can say except I've had a good buying experience and his stuff works well for me.
