Thanks for the feedback...t

Hi All, we've been asked repeatedly by customers if we would convert their full auto Uzi sear to a semi auto sear. We've been turning them away because we've just been too busy with other projects - because it's kind of a PIA to set up the machine to do 1 sear. But I have good news, I've...

Micro stocks: These have been pushed to the back of the line because we've just been swamped with other projects - the PSW bolts for the M11's and the .22 kit for the M10's specifically. Now that the PSW bolts are in the hands of their owners and we have a better handle on the .22 kits, we'll...

We set the bolt up to use the easiest to get and cheapest charging handle which is the hockey puck for the M11/NINE and we sell it on our website if anyone needs one. We were trying to make these bolts as inexpensively as possible to keep the cost down. If we had made with the provision for...

The bolts finally shipped to us. They will be here Monday and we'll start assembling and reshipping to those who bought one next week. Thanks to everyone for your patience. t

They've been delayed by the manufacturer again. I am working with them on the final inspection of parts. I am hopeful they will be shipping to us next week. We are sorry for the delay and we appreciate everyone's patience. t

We've worked with a new local firearms manufacturer to design an inexpensive yet effective .22 suppressor that has enough back pressure to reliably run our .22 kits. They are for sale now and they are $199.99 plus shipping to your dealer. Here's the link for more info...

Sam and I aren't sure how many Tom made, but we *think* he did 2 runs of the M11/NINE size bolts and 3 runs of the 380 size bolts - there are probably others here with more accurate details. We don't know how many in each of these runs. For PS-W bolts, you are correct with the 2 prototypes...

For those who've bought into this round of PSW bolts, I wanted to give an update. The bolts are a bit delayed from the fabricator. They told us they'd have half of the order ready at the end of December and the balance ready mid January. I told them to hold the entire order until they are all...

As promised here's the test run of the PS-W bolt in a large mag well 380 gun shooting 115 grain 9mm ammo. The shot meter registered 988. I hope everyone has a great holiday week. See video here t

For those following the progress of our PS-W bolt run, I have an update. Earlier this week we received the sample bolt from the new fabricator. It is a thing of beauty. We installed the extractor and rods/spring and took it out to test fire and it ran perfectly - see 1st video. Then the next...

Scott, Thank you for your kind words. We try to do our best and we try to be of value to the MAC community.

If you know you are going to want to run lower powered ammo, I'd suggest buying an additional 1-2 recoil springs to experiment with. I would also recommend you get you kit set up and running on the recommended 40 grain ammo first. Then once you know it's working well on your gun, start to...

Thank you! This is our 5th!!! We are blessed for sure. t

The consensus in the shop is that you more than likely have a brass caught in the upper. There are 2 places it might be caught. 1. Between the bolt carrier and the trunnion in the upper or underneath the trip in the lower receiver. Have you taken it apart (including removing the bolt from...

Here's a video of your kit running during the second and final test fire before shipping. Be sure to read the manual and watch the videos. Also, be sure to use recommended ammo. If you continue to have problems, please contact us and we'll help walk you through. If you need us to set it up...

Practical Solutions should be able to fix these for you if you don't find what you are looking for. Email me pictures and I can tell you for sure if we can do it and pricing. I'm at: tina@macmachineguns.com. Good luck. t

Correct. t

I'd be happy to answer any questions just send me an email at: tina@macmachineguns.com. Right now, the numbers on the wait list are not too accurate because I've been keeping all the names on one list regardless of grip/gun style. When people emailed me to be placed on the list, some of them...
