I haven't seen them mentioned anywhere around here. I was wondering if anyone had any personal experience with them. How reliable/ accurate/ well built are they? I would like to put together a basic 1911 frame and put one of these on it.



This is what I am talking about.

I have a Mech-Tech carbine in 10mm and it works great.
I also have a Colt Delta Elite and I bought a new Rock Island Armory G.I. 45 just for the lower frame to use in the Mech-Tech so that I could carry both at the same time.
The Rock Island Armory .45 was so good that I use it a lot.

10mm, when you care enough to send the very best.

The dark side of these uppers is that they permanently convert the legal status of your pistol frame into a rifle frame.  If you attach the Mech Tech to your 1911 pistol frame, then you cannot legally revert that frame back to pistol form unless you first register it as a Short Barrel Rifle via ATF Form 1.

He is correct. Once you use the Lower(pistol frame) on a barreled rifle upper, It is forever considered a "rifle". Revert it to its sub 16inch pistol form, you have illegally made an SBR. The first letter from the ATF in the link covers it, even though it pertains to an AR pistol.

Unfortunately, most Mech Tech owners are not aware of this and Mech Tech is not exactly clear about what their product does to customers' host firearms, legally speaking.

There are no "If" about it unfortunately, as much as I wish there were. Most of us who collect SBRs among other Title II weapons have been dealing with this very issues when we assemble our rifles. Truthfully, the ATF may never know of someone doing what you described in you post. However, we do have many discussions in the Class 3 section regarding Constructive Possession, which is just having the part available to build an SBR, which without paperwork is illegal. For instance, taking both your stock pistol slide and barrel with to the range while firing the lower attached to the Mech Tec could be considered constructive possession. In the eyes of the ATF, it seems just having the parts to assemble an illegal weapon is the same thing as having one.

I wonder what ATF's stance would be if MechTech were to get these uppers classified as firearms (serialized and all). If the upper/kit was the firearm, would the 1911 frame still become a rifle once assembled?
Link Posted: 6/17/2011 12:34:39 PM EDT

It would still be the same. Once it has a butt stock attached and has a rifled barrel 16 inches or more, it's a rifle forever. It's sad that such rules even exist, and that an otherwise lawful person could make an honest mistake that could land them in prison.

Thompson Contender won a court case involving this very same issue. While that case only applies to the TC  pistol/carbine kits, it does provide precedent for any court cases against a Mech Tech owner.

And as mentioned already. The ATF has no way of knowing if you are swapping back and forth. Don't take both the upper and the slide to public ranges at the same time and if you are really worried about the ATF having remote viewing capablities, don't store them together either.

I don't advocate breaking the law but I do advocate using common sense and not having irrational fear of the ATF. The only case I'm aware of someone getting convicted of possession under the "constructive possession" argument involved full auto parts, who's only function was to make a full auto gun, and it was one of many secondary charges to the primary charge in the case.

There are a number of companies selling 1911 and Glock (aliuminum) lowers. Just get a frame assembly kit from Brownells or elsewhere and have a dedicated carbine frame.

Holy crap!  My buddy has had one of these for years.  I talked him into buying it because I was really interested but didn't have a 1911 at the time.  

We've shot the hell out of this thing.  He uses a Kimber Pro Carry, which is his only handgun.  With this set up, he has a handgun and a carbine, just switches the frame out for whatever he wants to do at the time.  He'll shoot the carbine, pop the frame off, and head over to the pistol range.

I never even considered this.  I advised him quite some time ago to just pick up a cheap frame for the carbine and leave it set up.  He isn't a "gun guy", so he just never got around to it.

OP, to answer your question, he has had this thing for several years and we both shoot it regularly.  No idea what the round count would be.  Never had any problem whatsoever.  He's got a cheap red dot mounted and we shoot it out to 100 yards.  Accuracy and reliability have never been a problem.

Holy crap!  Thanks guys, I need to make a phone call...

I sent a letter to the ATF asking about this very issue (going back and forth from Mech Tech Carbine to pistol), before I bought one.  I waited a month and a half, thinking that they'd just lost or thrown away my letter.  Apparently, they were just taking their time.

Today, I got their response:

http://i78.photobucket.com/albums/j85/koimprobable/guns/atfmechtech002.jpg <–– Page2
(pictures edited to remove my personal info, only)

If the lower has never been assembled as a pistol, you put a Mech Tech upper on it, and then turn it into a pistol, then, and only then, are you making an NFA item.

That said, I'm still going to keep this letter in a safe place so that if some ATF agent has a different interpretation, I have something to defend myself with in court.

It seems that the logic of the ruling is thus:

Putting the MT Upper on your Glock or 1911 makes it into a rifle.
Reassembled as a pistol, the frame becomes a firearm again because it is under 26" OAL and 16" barrel, and was made from a rifle.

I think there's a logical step not explicit in the letter where the item in question doesn't fall into any NFA categories (despite our belief that it is an SBR).  If anything, I guess it isn't an SBR because it's not shot form the shoulder.

So can we take the butt stocks off of our AR receivers, and install barrels shorter than 16" now?

True dat, but ATF would have a hard time in court saying persons in identical situations should be charged differently.  Equal protection and all that.

Anyone know of any cases where they did prosecute differently?

Thanks for posting this.

This letter along with the T/C letter (and others I'm sure) both just confirm what the regulations say :

Pistol - A weapon originally designed, made, and intended...when held in one hand...

Configuring a pistol as a rifle does not magically change it's original legal status of being a pistol just as configuring a rifle (>16" and >26") as a pistol (<16" and no stock) does not magically change it's original legal status of being a rifle.

Types of firearms are what they were ORIGINNALY configured as. Just as most Title 1 firearms that have been used to make Title 2 firearms are no longer considered Title 2 firearms when returned to Title 1 configuration.

I am going to go out on a limb and predict that this type of determination, based on the definition of 'pistol', could also be used to prove that adding a forward grip to a handgun does NOT turn it into an AOW. Contrary to current opinion. Only time will tell.

Hardshell,

I wholeheartedly agree with your suggestions. What I am saying is that these couple opinions support what the regulations say. Not that the regulations need any supporting because they still mean what they say even though some employees of the atf have poor reading comprehension skills.

The letter you posted above presumes that some magical transformation of the receiver has taken place and a rifle is the result of adding a buttstock and >16" barrel to a handgun (not in that order). What you have is a pistol receiver with a long barrel and a buttstock - a Mech Tech conversion.  Nothing more nothing less. A similar issue arrises when a person submits a Form 1 to 'make' an NFA firearm.

Using atf reasoning, adding a spoiler and racing slicks to my 4x4 truck would magically transform it into a race car. Or adding mud tires to my car would magically transform it into a monster truck.

While the atf is not usually known for using logic in their decisions, the links to the original posted above prove that there is at least one person there with the capability of fundamental reading comprehension and the proper application thereof.

Do I want to be the test case? NO!

But it will be interesting to follow these opinion letters from atf in the future.

Yep, that ruling (published as a ruling instead of a letter to an individual) is HUGE!

It still makes it clear that one cannot make a pistol from something that started as a rifle, but it finally (and sensibly IMO) states definitively that adding a carbine kit to a pistol does not render it forever more as a rifle... which, ironically, is directly contrary to years' worth of their own opinions and letters on the subject.

I strongly suspect the recent availbilty of the Beretta NEOS carbine kits, added to the MechTechs and other conversions already on the market, prompted this. It's neat to see a BATFE ruling that actually makes sense. (And I bet the folks at MechTech are doing a happy dance. )

I know that this means I will definitely be getting a MT for my G21s, and I might even revisit the NEOS again...





ETA:  This is also an incentive for AR hobbyists to build most/all of their stripped ARs into a pistol configuration first, before ever putting them in rifle configuration, so that they can also be put back in pistol configuration if the future if desired.







Just an FYI - installing the buttstock the very last thing would technically suffice to make it considered a pistol since that would satify the held and fired with one hand without a buttstock requirement.

Yep, that's probably sufficient... but, me being one who errs on the side of caution WRT gun laws (some would even call me paranoid, and that's okay), I'll probably completely assemble them with a pistol tube and upper first (and take pics) just the same.

Just for clairification: I want to make sure I have this right...

On the 4473 the Stripped lower will still be transfered as "other" becasue it doesnt meet the definition of a rifle or pistol.  

Build Stripped lower as a pistol with no buttstock and barrel less then 16".  Take photos, test fire and enjoy.

We can "upgrade" the pistol to a rifle.  Buttstock and barrel Greater then 16". Take photos, test fire and enjoy.

Then we can revert it back with no reprocussions because it was built as a pistol first? .

I think this matter has been cleared up. You can make a carbine from a pistol and then change it back. But, as has been pointed out, if it started life as a rifle it is always a rifle. Having a kit to convert back and forth is NOT a crime as some would have us believe. The courts have made it clear. The ATF got bitch-slapped on that one. But, they will keep trying to screw us over. Look at who Obama-man wants to appoint to head the ATF.

Also, if you don't currently have a pistol length upper, test fire the upper with any length barreled upper and you still have a pistol. Being a pistol isn't contingent upon a certain barrel length––-just the absence of a stock on the gun.

You could always do this, this is just like the forward grip on a pistol. The ruling is just something the ATF made up. You can not be convicted of this and magistrates or judges should never issue a warrant for this because it simply does not meet the code section.

If you ever get arrested for this contact a lawyer. After the case gets thrown out file a 1983 claim (they will know what that means.) The money you get for your rights being violated will more than make up for any problems. I also urge anyone charged with a TSA violation to do the same thing.

This is hashed out all the time in the Class 3 section - once you put your SBR into a non-SBR configuration, it's no longer an SBR. Search over in Class 3 legal, you'll see dozens of threads on this.
