maxfaxdude Posted January 20 Report Share Posted January 20 I had heard of a fully transferable PKM with registered trigger but never seen one until this just popped up on Gunbroker: https://www.gunbroker.com/item/1085298002 Does anyone have more info on these transferable triggers?

1gewehr Posted January 20 Report Share Posted January 20 "The fully transferable part of this gun is the M11 .380 trigger" This sounds suspiciously like the people that took registered MAC10 receivers and transferred the serial numbers on to more valuable parts kits, making a new machine gun with a 'registered' serial number. I'd be VERY careful! 1 Link to comment Share on other sites More sharing options...
tricky9914 Posted January 20 Report Share Posted January 20 As stated, years ago someone removed serial numbers from MAC 10s and placed them into M60 receivers. Those were determined to be a "no-go" with the ATF. Also, I recall someone doing something similar with M249 kits which also lead to much debate (one of those M249s showed up on Sturmgewehr 4-5 years ago and the debate was heated). I would also be very very careful with this one. Link to comment Share on other sites More sharing options...
villafuego Posted January 20 Report Share Posted January 20 Those Broadhead Armory MAC triggers were purpose built, pre-86 conversion devices ......for the MAC family of firearms ......they dropped in to a semi open bolt MAC, and converted the gun to FA-only with no modification to the host firearm. The real issue would be, would their use be allowed in a completely different type of firearm? ........ You can't even use a reg. FNC sear in a SCAR....... 2nd question would be, remove that trigger and what do you have left? Is it a PKM capable of accepting an open bolt firing mechanism ? The registered trigger is the least "sketchy" aspect of this whole thing Link to comment Share on other sites More sharing options...

I would also be very very careful with this one. This is not remotely close to the MAC fiasco which utilized serial numbers and pieces from a registered receiver implanted on a new receiver. These broadhead items are solely conversion parts and not firearms. The M249 product is however very similar. I was probably involved in the debate, which really wasn't much of a debate. The atf letter posted with this GB auction pretty much sums up my position on the 249 issue. If you read your forms correctly there is no stipulation as to what firearm a conversion device is used in. All of those "opinions" have been pure speculation and opinion, yet the letter in this auction makes it clear there are no firearms specified for conversion devices, but once removed the firearm can't be in an illegal configuration, thus it could not be an open bolt MG among other things. Much like pulling an HK sear out of and HK94 that the barrel had been chopped down below 16"...... a no go without secondary SBR registration. Broadhead and others made a number of "not well known" gadgets. DLO did a lot of the same thing as did others back in the day. "Sketchy" is also how most trap shooters refer to MG owners, but that doesn't make it so? Were it not for the crazy price I'd probably be interested?

maxfaxdude Posted January 21 Author Report Share Posted January 21 The picture of ATF letter supplied by the seller in the GB auction makes it seem (al least to me) that these devices are legit. But...it does make me wary. And $150,000 is an awfully steep price! Link to comment Share on other sites More sharing options...

WJP Posted February 1 Report Share Posted February 1 (edited) Personally you wouldn't catch me owning it. You would need illegal parts to get them to run the way the Wiselite designed them. Pretty much like having a closed bolt semi uzi and a registered trigger group. You would need to cut a slot in a factory open bolt to work with the registered trigger group. They have denials for the bolt, carrier, and the firing pin. If you pulled that trigger out and just dropped in the converted bolt and carrier it should just run away. Same as pulling out most open bolt guns triggers and racking the bolt. I'm not going to say it's illegal since I don't know the full conversion. However would you slot an uzi bolt to work with that trigger? Edited February 2 by WJP Link to comment Share on other sites More sharing options...
BRMCII Posted February 2 Report Share Posted February 2 If the seller is serious about ATF authorization of his legal use of the registered trigger, he would send a registered trigger and a semi-auto PK to Tech Branch for an evaluation of the potential use of the device for an approval for it's use in the PK application. If he sends the trigger and semi- PK he won't get in trouble for having created a post-May sample which they might not return. Let Tech look at it and decide what alterations are required, if any, and if the conversion would meet their legal requirements. They might ask for a converted example to evaluate which is riskier but the reward is substantial. His letter is an only a generic approval of the use of registered conversion devices in semi-autos and the legal requirements to do so, but it is NOT specifically for the PK. That is a huge leap of faith. I have a postie PK and have repaired a few so they are familiar but I don't have a semi so can't say anything about the trigger's use in one. My $.02......

WJP Posted Monday at 12:24 AM Report Share Posted Monday at 12:24 AM (edited) I just looked at the auction again and a semi in person. It almost appears that the lower denial was pulled out of that receiver. I would definitely ask what method was used and for pictures of the entire inside of the receiver without the carrier installed. Of course the listing says the denials are in place. Just seems a little off to me. Edited Monday at 12:34 AM by WJP Link to comment Share on other sites More sharing options...
