New MAX-11/15 Videos

I can hear the chant for a video of the irm, anybody else hear that haha

remember its open bolt, so it will run cooler than a M16

on one hand he has guys asking over and over about pricing on the other hand he has guys asking for extra's that add expense...and in the end he needs to come up with 1 setup and people can customize their own off of that...

i think Mr. Lage just kept himself busy for many, many years to come with this upper and all the other potential spin offs from it (shotgun, AK, etc)

Yeah I think features should be very basic, keeping the price down and letting people customize themselves. Although a heavy barrel is probably something everyone can get behind and add little or no expense. In fact I think heavy barrels are sometimes cheaper because there is less material to remove in the machining process.

 

[bac0nfat]

Also, doesn't the fact that it's open bolt only mean that it cools between bursts? If you are doing mag dumps I think it would be the same as an M16.

i just remember the finish that melted off my m16 suppressor after 3 mags of fast firing with limited rest.....lots of mac owners used to subguns are going to be surprised how hot a .223 barrel can get quickly....i let my .223 FA's rest 5 mins now in between mags....my Ruger gets as much as 10 minutes as it has that nice pencil barrel

i personally vote for making this thing as heavy duty as possible...spare no expense....but others would disagree and could be priced out of the upper...

AR mods are cheap and often can be done on a work bench w/ no gunsmith costs...so swapping out a barrel shouldnt be a big deal

We had a chance to shoot two Pre-Beta Test Unit MAX-11/15's today at an informal desert shoot. Everything went very well.

Nice. How many rounds do you estimate you put through the two test units on Saturday? All I heard the whole time was mag dump after mag dump after mag dump after mag dump... someone shooting singles... someone shooting doubles and triples... then mag dump after mag dump after mag dump.

Reliability is off the charts!

I know its a long way off, but it would be nice to get one in 5.45x39 since F/A in that caliber is on the rarer side

Personally, I don't think there would be a significant temperature difference in the barrel. Yes, open bolt will help a little to cool the barrel if there is time between bursts. It is my understanding that the vast majority of the heat in a barrel is from the friction of the bullet and the surface of the bore. I predict the biggest determining factor with be the mechanism. DI is cheaper than long stroke or short stroke piston designs. I've melted a couple of DI gas tubes in my time. Using Beta C mags, usually a carbine gas tube will fail somewhere between 200-300 rounds. One failed at around 220 and the other two were 260-270. With a 7.5" barrel the gas tube burst at 180 rounds.

Piston systems can pound Beta mag after Beta mag. To me the gas tube acts like a shear pin. It breaks before that is any real damage done to the barrel. With a piston system the barrel can be destroyed. I have heard of barrels getting so hot that the barrel droops when red hot and the bullets could got through the side of the barrel. I have never done this as that seems very dangerous to me. That is the real advantage to the M16. Push two pins and install a fresh upper. I hear there are quick change barrels systems for the AR. I would think the Lage system could benefit from this. But that is a personal preference thing for each owner to decide.

I personally think the spring could be housed inside the upper would be approved, as long as one end is held by the inside of the M11/9 receiver, just like the original design spring. But the magwell would need to be pushed forward to use standard AR buffers. There are a couple of PDW style buffer systems. But with limited length comes limited mass. Shorter barrels tend to need heavier buffers or there is bolt bounce issues. YMMV.

The guy in the third video is super sexy! If I could look like him I will defiantly be buying one! Oh that is me.

 

[bbrown]

Any plans to make a version for the M11a1?

Since you have 1st hand experience with it, what do you think about it in comparison to an M16? Recoil, balance, etc.

Balances well, it is light, around 7.5lbs. Shoots smoother than a standard, short barrel M16 to me. Easy to pull singles. With IMI ammo ROF was 720.
IDK how many rounds were shot through the uppers that day, I know I shot 2 betas and about 10, 30rd mags.

 

[Scott C.]

Smooth. It shot very smooth. I shoot my m-16 mostly as a light machine gun from a table or on the ground. I think because of the extra long leangth and open bolt setup there was no choppiness. Very smooth!

 

[Mackjack]

I noticed in the videos the m11\9 reciever appeared to be in the white. I imagine you use post samples to test with? Have you ever had anything in testing actually hurt a lower to the point of it being a problem? Just curious what type of risks are involved, specifically with a 223 upper. Not sure what the risks would be, perhaps hole egging, or bending the reciever like incorrectly attempting to run 9mm luger in a m11a1?

Just curious. I'm as excited as everyone else. But.... If I break my m11/9 somehow I'll be sad. Sorry if I'm being a worry wart guys

Yes, the guns in the videos are posties. To give you a reference point for "wear and tear", I tested the MAX-11/15 using a plastic (Delrin-Black Acetate) retaining pin and it did not break or dent it.

Most wear or deformation of the retaining pin hole is going to come from movement of the upper relative to the lower receiver. It bounces back and forth when firing. The MAX-11/15 includes a stock adapter for the stock and buffer system. We will be including an adjustable stock block that tightens up this play.

I like the plastic pin test. That is very reassuring and is a pretty straight forward and simple way to prove the forces.

What about the sear axis pin hole egging? Like as seen with the old stony creek armory uppers? I would imagine that is more of a result of the reciprocating mass with the bolt group.

If I remember right, that was because on the SCA upper the sear catch on the bolt was positioned poorly and the bolt would get a running start at the sear. This is not the case with the MAX11/15

wonder if the loss of 2" in the back of the upper makes the IBS not an option?

 

[LawBob]

I doubt it. There’s 7” of space between the trunion and the rear.

Loss of 2" in the back my cause ibs.... But Idk How it'll affect the IRM

I think it is the opposite. High temperature gas is the main cause of barrel heating. But the main advantage to open bolt isn't so much that it cools faster, it keeps the next round from heating.

The brass case has very little friction comparatively and will burn you badly right after firing.

Gas port erosion, hottest areas of the barrel closest to the chamber all point to the high temperature gas.
