Options on slowing down the M11-9

[Brockak47]

So as some of you may know, I have an M11-9 on transfer to me. What are my options when it comes to slowing this thing down. I would hope for around 700 RPM or under, but any reduction is good.

Are my only options the Lage slowfire upper and a TASK style conversion?

Are there cheap options?

Thats pretty much it, you could go custom and try to find someone to do tungsten inserts on the bolt or try and find a gunparts/autowerkes rate reducer. Neither of which is going to work as well as the lage or TASK.

If you want to bother to try and track down a heavy bolt, this guy posted about having on another forum:

Get the Lage. Worth every penny transforms the gun.

Get the Max 11 upper, grip and fixed stock. You won't ever want to go back.

YMMV but years later it hasn't gotten old.

Couldn't agree with this more. In retrospect, I wish I'd have opted for the speedbolt from the outset, but just the standard Max-11 is a monster improvement. With the Lage upper, molded grip, collapsible stock, and extended safety, it is truly a pleasure to shoot. Also, it sounds like a woodpecker on heroin from a couple hundred yards away

Not the only options, but by far the most common. Any other slow-fire mods I've seen were either one-offs, low production, or less than effective. For cheap, the TASK method is tough to beat. You can do it yourself for the cost of an AR15 stock setup and a mounting bracket.

I remember reading in an old issue of Small Arms Review where Monty Mendenhall noted that he and Jim Weaver came up with the TASK system, to give competitors an effective, low-cost competition gun, without having to fork over $3500 for an MP5. :shocked (yeah - those were the days).

If you're not so sure about working on your gun yourself, you can get the basic conversion done by Jim Weaver for about half the cost of a Lage upper. http://cncgunsparts.com/task_slowfire_conversions

IMO, the TASK conversion is the more versatile of the two systems. It also seems smoother to me. The Lage seems a little more choppy - not unlike shooting an Uzi. But still very controllable.

You can see I've got multiple options for playing with buffer weights and styles, as well as spring weights and lengths. Anything from high-speed to stupid slow, and everything in between.

Having said that, how often are you really going to want to adjust your ROF by 50 RPM? If you're like me, you want one or two speeds and you're good to go. Others have said it, and I tend to agree that if Lage had introduced his upper early enough, the TASK system would never have been invented. There would have been no need. Had I started with a Lage upper, I wouldn't have bothered to do the TASK conversion.

If you don't like the rates of fire of the standard Lage bolt offerings, take a heavy bolt weight and start hacking until you get the ROF you want. I made my own Tac bolt with nothing but a dremil cutoff tool and a file.

Having both systems, I'd be hard pressed to say which I like the best. They both do very well. Actually, I currently run the TASK upper in Open / Optics category at subgun matches, and switch to the Lage upper for the Iron Sight category.

Here's a comparison of the two. I think this is with the standard (heavy) bolt weight on the MAX-11. The one I'm running now is a little faster.

What appeals to me about the TASK is the relative cheap price and the ability to do it myself also it seems to keep it compact where as the Max makes it a bit longer. The only thing that concerns me, does the hole in the rear of the receiver I have to drill would that lower the value of the gun or keep me from running it stock (or otherwise limit me from what I can do with a stock M11/9?), would I always have to have the AR adapter on?

If / when the S.A.B.R.E. .223 upper is released, I see a lot more M11/9s getting the back plate drilled. What I don't know yet is if the hole is in the same place for both conversions.

As for the TASK conversion being more compact - not so much. While the Lage upper is longer, you have the option there of using a folding stock. With the TASK conversion, you are stuck with an M4 stock as your shortest option. (I prefer the A1 stock, as it allows heavier buffers).

The hole won't keep you from being able to run a stock or Lage upper. The back plate that holds the recoil rod and ejector covers the hole. It runs fine with the hole there.

As you can see, my back plate had been rewelded some time in the past anyway. So I wasn't really worried about loosing any "value" by poking a hole in it. Worst case, I just cut the back plate off and weld a new one on.

Does Task lower the price? Short answer it depends. Personally I would have (and did not) buy one. Also didn't want a sten conversion. So me yes, guy wanting a shooter maybe not.

And yes you can still run it stock just have a hole staring back at you.

That being said I may very well drill mine to get the AA .223 upper. But that is just because I have to. My opinion is the Lage is the best for slowing down in 9mm.

As to length. Search Max 11k.

If you want to slow it down shot it in semi........

AH! duh, I was thinking you could put a ace style folder on it, but then where would the buffer go. Facepalm.
so the Lage is the more compact, while the TASK is cheaper?
On the hole in the receiver, I did not know the SABRE upper also needs a hole drilled which I plan on buying if they release, as I am on the waiting list. So maybe task may work better for me. Unless I want the same money invested in uppers as the gun itself,lol.




thanks for all the input guys

There are other things about the TASK conversion you may need to address too, depending on how far you want to push it.

Side cocking upper?
Foregrip?
Optic?

It's quite possible that you'll get up to $350 when you're all done. Don't get me wrong, I did the TASK conversion to mine and you will learn a lot about how these little subguns work, but I found myself always trying to get it "just right." Then I went Lage... of course I modified my MAX-11 upper to get it "just right" too.
