CW

You can buy frames (including internals), and they are a lot less than compete pistols.

However, if you don't have a G21, and want one, buying a complete G21 would be the way to go. As far as "dedicated carbine" goes, they're so easy to switch (no more difficult than a field strip), you could have the best of both worlds.

I don't have the actual velocities yet (will on Sunday), but everything indicates you are about right on with what I'm seeing (hearing). A gong report at 150 yds is noticeably faster with the .40 carbine, than a factory power 10mm round from the G20 with a 5.2" barrel. Also 180 gr. cast for both.

MichiGun, dm and modglock,

I didn't even realize we were talking about a .40SW MechTech... lol... but the same still applies I guess.

Well, I know they're talking about .40 but I'm talking about MechTech in general and 10mm.

See, with the .40, they're doing 1,600fps. With the lame 10mm dose, we'd be seeing the neighborhood of that speed.

My reluctance to go Mechtech thus far, is the hot 10mm rounds: if it goes 1,500fps (135gr HOT) with a 6" barrel,

1. would it burst the MechTech burst ???????

2. would I need to reload "lame" 10mm just for the MechTech??? Then we're not exactly talking about the same ammo for my G20 and a future MechTech.

3. Look at it another way, I am looking for Underwood to say something about NOT using their ammo in a MechTech.

4. I go cheap, with plated bullets. They have a max speed before they tumble, roughly 1,200fps. You can see the picture... Forget accuracy! So we are really talking about a different ammo and reloading for a 10mm MechTech.

Am I making sense ?

With the .40 ammo, it is a good route!

[Cwlongshot]

I haven't read anything about it not handling all 10mm loadings. Mine will likely never see a factory load!

The 21 is something I would like and it's also something I would not use allot. Which is biggest reason I don't have one.

I will need to send some emails to mech tech and see what the consensus is about the barrels. I hope they are atleast as supported as a stick GLOCK is. Hoping it has better support like my KKM or LW barrels do.

Of coarse you don't "need" these top performing loads cause your gonna get at least a couple hundred additional FPS simply from a longer 16" barrel

BUT a bit more or wanting all you can get is American as apple pie and leamonade and Sunday dinner....

Also been reading allot about the funny/funky noise upon firing. I'm assuming most of you have shot a AR rifle... The spring in the butt doesn't sound funny to you??? Along these lines it's my guess the butt you choose will have everything to do with this noise.
I'm going to run a solid but with a foam top. Do not know the actual name.

Another question I've been wanting to know. I see these in AR fore des and like the look funtionality. It looks like a "v" with the open top mounted to the tube allowing you to hook this on something. Or and at the same time pull the rifle into your shoulder. What is this and where can I get it? I'll try to find a pic if no one can figure out what I am describing.

CW,

I thought the guy from MTech recommend dropping bathtub silicon on the recoil spring to keep it from zinging.

[Cwlongshot]

Thanks man I had not herd that..

OK I did some searhing and the forend piece I like is this:



The butts I am thinking of is this:



BUT I just saw and like this one too. This one will allow it to colapse too...

Yep. Basically, the spring acts like a tuning fork. So you damp it out by putting a chunk of bathtub silicone on it.

Here's another example of a huge tuning fork that didn't turn out well.

Lol Mod I know exactly what you mean regarding your list a few posts back.

And LOL about the bridge video. I remember watching that in physics in high school ... Vibration and oscillation lesson. :-)

CW - yes! Ask MT about the 10mm / blowback issue....

I just brought up the .40 as an example, wasn't trying to change the subject. Just pointing out what the 10mm Mechtech should do, based on my experience with .40.

[dixietoo]

I am waiting on my G20 to get here. Soon I want to get the MT for it. Do you think an M4 stock with a cheek riser would be good? And that fore end, better than one that is perpendicular?

[blackgun556]

here is a pic of the chamber support in the mt. I have a lw and a storm lake barrel and the support looks just as good. I have loaded pretty hot not to the full and have never had any bulges in new cases

I was NEVER referring to the Mech Tech in .40sw, other than when i said i got the wife one for her glock. If you hear anything about the Mech Tech from me it WILL BE in 10mm! I have no worries of hot loaded 10mm rounds in mine. After many many many rounds through mine it is perfectly fine. If you read your manual or even call Mech Tech Systems they will advise you to run the warmer ammo.

1600 fps with a 180gr XTP using Longshot is not hard to get with the 10mm Mech Tech. I know because this is what i shoot. Although i would be very surprised if one could do that with a .40sw using a 180gr bullet. I can tell you that i will never try that using a 40sw. The .40sw in no way can SAFELY equal the 10mm in ANY firearm. Like saying a .38 special can equal a .357 mag. Thats my story and im sticking to it!!!

No one suggested matching a .40 to 10mm. My comment was regarding a comparison of the MT .40 and a 10mm pistol, at that time, while shooting both side by side. Nothing more.

My .38 Spl is way more powerful than your .357 Mag.

My post was in no way aimed at you dm1906 or anything you wrote. In fact i read your comparison of the .40 MT & 10mm pistol clear as could be. But, I did read in this topic where someone had posted 1500, maybe 1600+ using a 180gr bullet from there experiences using a .40 with a 16" barrel. Maybe i read that out of context. You are right, there is no comparison between the two. 10mm always wins!!!!

Would love to hear about this .38 spl you have that is way more powerful than a .357 mag though. Thats something i have never seen or heard of before.

THANK YOU for the pic BG!!!

[nickE10mm]

Yes, thank you for the pic, BG! A little closer would be even better...

And no, a .40SW will never safely equal a 10mm with full loadings... ever...

And yes, I would like a MechTech unit for my G20sf ... badly. :-/

With the .40 ammo, it is a good route!

The mass of the chamber and bolt appears to be quite capable of handling any (otherwise) safe load. Chamber support appears to be as good as any aftermarket barrel.

"Bursting" the Mech Tech isn't the concern. Bursting the case is. "Blow back" action is never "locked" into battery. Only spring tension holds the bolt/breach to the chamber. Spring weight/rate and bolt mass determines the extraction event and bolt velocity. If the powder is too slow for the conditions, pressure will still be rising during extraction, which can allow the case to be unsupported. This is bad. The spring weight/rate can be increased to compensate for heavier/slower loads, but it may prevent lighter loads from cycling properly. It's probably no big deal with the .40, as a 10mm spring can be substituted. The problem with the 10mm, if it becomes an issue, is it's already the heaviest of the options. A custom spring may be the solution. Perhaps a spring shim, or adding bolt mass, if the mechanics allow that. I dunno, it may be a non-issue. Just thinking ahead, based on past experience. I do know what 9mm +P does to a Sten, and it ain't pretty. .380 will balloon cases if the powder is too slow, even at very modest pressures.

I wouldn't consider the "common" plated bullet options (Berry's, Ranier, Frontier). I can vaporize these at will. Perhaps one of the "heavy plated" options, like Hornady TMJ. Berry's off the shelf .40 bullets are a no-go, even at modest 10mm loading. Their .41M bullets do fine at very high velocities. A resized Berry's .41M bullet does very well in the 10mm, and as fast as I can push them with .38-40 (scary fast), but way too long for use in a .40 S&W.

[Any Cal.]

So is the recoil considerably heavier than expected, due to the mass of the bolt? Some of the 9mm carbines (Uzi, Ruger) are really slow even with light loads due to the time the bolt spends riding back and forth. Is the Mech-Tech similar, due to the straight blow-back action?

I know that even locked breech stuff recoils w/ pistol calibers, but it doesn't seem to move around so long. Any thoughts from somebody who has experience with any of these?

I think you just misunderstood my post. It was intended more like "If the .40 can do this, then the 10mm can do that". I've pushed a 180gr cast bullet to 1500fps out of a .40 S&W blowback carbine (not Mechtech), although that load was a bit too hot. Based on that, I was saying the 10mm Mechtech should do 1500 or 1600 fps with the same bullet.

No drama intended here; I think we all know the difference between .40 and 10mm.

[mscott]

I have 3 of these things and got to say they are very fun. I use them for 3 gun matches since we don't have anything over 100 yards on most of the matches here. I got tired of moving things around and now have 2 dedicated frames for them. Here's a 9mm version somewhat customized.



I've also been working on the bolt. I decided to flute one in an effort to shave weight and reduce friction inside the unit and maybe allow the use of lighter ammo.

Chiming in here on pistol versus barrel length velocities (in reference to the MechTech 10). Recommend checking out this YouTube posting by
drsjr1969 10mm ammo Ultimate test Glock 20 and Mech-tech


https://www.youtube.com/watch?v=GUyQ-E9aEnI

In short, using a Shooting Chrony, he does a very nice job of comparing several factory loads from the standard 4.6" G20 to the Lone Wolf 6" to the MechTech 16" carbine...the results of which are very revealing for the high performance enthusiast! In short, plays out like this:

Video shows testing of Glock G20 with 6" Lone Wolf barrel and the MechTech 16" Carbine using the following ammo:
1. Underwood 135gr HP
2. Georgia Arms 155gr HP
3. Underwood 165gr HP
4. Buffalo Bore 180gr HP

Also shows velocity of the standard 4.6" Glock barrel as well:

• 135gr Underwood
4.6" Barrel: 1558fps
6" Barrel: 1735fps (+175fps)
16" Barrel: 2020fps (+462fps)
• 155gr GA Arms
4.6" Barrel: 1329fps
6" Barrel: 1470fps (+140fps)
16" Barrel: 1650fps (+321fps)
• 165gr Underwood
4.6" Barrel: 1361fps
6" Barrel: 1485fps (+125fps)
16" Barrel: 1695fps (+334fps)
• 180gr BuffaloBore
4.6" Barrel: 1327fps
6" Barrel: 1452fps (+125fps)
16" Barrel: 1565fps (+238fps)

Now those are some very worthwhile numbers detailing a substantial improvement over the OE barrel. And yes, the MechTech uppers are hell-for-stout strong!

If you've interest in a 10mm carbine, the MechTech is an excellent path to a very versatile multi-platform weapon system.

Hey, thanks for posting about my info and linking my video.

I wish more people would get the 10mm info out there to get people to see what there missing.

Most under rated cartridge out there.
