New Product Release: MAX-31C and MAX-10/31k 5/05/2021

The highly requested shortened Suomi Drum Uppers for the M-11/9 and M-10 will be finished soon!
At approximately 2-1/2" shorter than the original drum Uppers, they make a great host for use with a suppressor. The M-11/9 version is called the MAX-31C and the M-10 version is called the MAX-10/31k. A waiting list is being formed for both Uppers.

Status update on the MAX-10/15 and MAX-11A1/15 upper receivers. 03/11/21

Regarding the status of the MAX-10/15 and MAX-11A1/15 upper receivers we submitted to BATFE Firearms and Technology Division, we still have not received a determination letter from BATFE. We will not go into production until we hear back. As soon as we have an update we will post it here and on our social media accounts. has been revised to a more current format! 08/12/20

We experienced an attack on our website in June that caused alot of dysfunction with our website. While we had attempted to restore functionality, it seemed best to just redo the whole website. This new format should be easier for you to navigate and use. We hope you like it!

Status update on the MAX-10/15 and MAX-11A1/15 upper receivers. 08/12/20

Regarding the status of the MAX-10/15 and MAX-11A1/15 upper receivers we submitted to BATFE Firearms and Technology Division, we called to leave a message the other day and their system will not let you leave a message anymore. The old system used to be that you would call, leave a message and an agent would call you back within 24 hours. We called and left a message about 6 months ago and they never returned it. Instead of reaching voicemail, you hear a recording of their mail in address. We will write a letter, but it's probably pointless. There might be agents working from home due to Covid, but I doubt it. Our best guess is that we will hear something early next year.

MAX-11/15 IRM versus AR Buffer system 06/16/2018:

There have been alot of questions about which recoil system a customer might want for their MAX-11/15 so here is some more information.

I am not going to go into the details of the IRM (Internal Recoil Mechanism) while we are going through the patent process for the upper. When we have Patent Pending status, I'll show details, pix and video. We will have Patent Pending before the first unit is sold.

All I can say is that the upper with the IRM assembles on the the lower receiver with no modification to the lower receiver. There is a step you need to do before removing the upper to make it easier to re-install the upper once it is removed. If you forget this step, you will have to do a different step before you re-install the upper again. No screws involved. Not a bunch of complex parts to deal with. You will have to trust me that it is simple and convenient to use.

For the AR Buffer version, you do have to drill a hole in the lower receiver and install the AR Stock Assembly (AR Stock Adapter with AR Stock, Buffer Tube, Buffer and Spring). To change stocks, all you have to do is remove the one screw that secures the AR Stock Assembly to the Lower Receiver and install the stock you prefer.

With the IRM, you can use any stock you want, including an AR stock. You can also use a Folding or Collapsible stock which is something you cannot do with the AR Buffer version.

With the AR Buffer version you have to use a stock system with an AR Buffer Tube, Buffer and Spring. With this system, you can experiment with different buffers and springs to tweak the system, if necessary, for different calibers.

So far, .223 Remington, 5.5x45mm and .300 BLK has been tested in both systems and they both work equally well in both systems. We know that some customers are going to want to try different calibers and the ability to tweak the buffer system may help with that.

In order to maximize production and get MAX-11/15s in customer's hands as soon as possible, we will be offering only one configuration- 5.56x45mm caliber and a 10-1/2" barrel.

BATFE Tech Branch has approved both versions of the MAX-11/15 06/13/2018:

We have received our determination letter from the BATFE and they have approved both versions of the MAX-11/15! We will start production right away and hope to have the first 20 ready in a few months. After the first run we will increase the quantity of each run with the goal of doing a minimum of 50 per 4-6 weeks. Since both versions were approved you will be contacted a month or two prior to the run that you are going to be in and we will ask you which version you would like (AR Recoil System or Internal Recoil Mechanism). There will be no price difference between the two options. The price for the MAX-11/15 will be finalized when the first production run is completed but it is estimated to be $2,995. We estimate to reach the end of the current list in approximately 18 months. We will continue to post updates of the status on our website.

MAX-11/15 Project Status Update 05/23/18

We submitted the original prototype that was provided by MAK91 to BATFE Tech Branch and received an "Approval Letter". Yes, in theory, we could produce and sell that version right now. The letter specifically stated that if there were any changes in dimensions and/or materials, we would have to re-submit the design. We redesigned the upper and also came up with a "non-drilled" version. These versions have been at BATFE Tech branch for a while now and based on the latest conversation with the agent who it was assigned to, the determination should be finished in a couple of weeks. This is the same agent who made the original determination. He is familiar with the design and all of our past products and letters. The conversation was a positive one.

The Beta testers are continuing to test the Beta Units and at least two of them have well over 12,000 rounds through them. When we get "Approval" of the design, we will have the Beta testers return the Beta Units and Shooting Logs for inspection. After that, we will start production. All tooling is already manufactured, so production will start fairly quickly.

Spots on Waiting Lists are No Longer Transferable

Effective as of 04/11/2018: In order to maintain integrity of our waiting list and ordering process, product must be paid for and shipped to the customer on the list. Your spot on the list is not transferable under any circumstances. If you had contacted us in the past to transfer your spot to someone else and we updated our list to change it to their name, we will honor the change.

First production run of MAX-10/31 Upper Receivers are finished

We have just finished the first production run of MAX-10/31's and will be notifying customers on the waiting list on Monday, 08/01/17. The next batch will be finished in about a month.

Maintenance of your Zytel Magazines:

If you are using Zytel magazines with your MAX-11, you will need to keep them clean for optimal performance. Any carbon fouling or grit will cause problems with the plastic follower against plastic magazine body.

I typically clean my Zytel magazines before every subgun match; once or twice a month. Also, keep in mind that using a suppressor with the MAX-11 will accelerate fouling of the magazines.

Here is the cleaning procedure I use:

1) Use mineral spirits and a bottle brush to clean the inside of the magazine.
2) Blow them out with compressed air.
3) Clean the springs and follower with mineral spirits and a brush and blow dry.
4) Squirt dry graphite powder (the type used for locks) into both ends of the magazine body and shake it around inside the magazine until it is consistently dusted inside. Shake out any excess graphite.
5) Re-assemble the magazine and squirt a little graphite on top of the magazine follower.
Some customers prefer to use a spray silicone lubricant instead of powdered graphite.
