Back from the dead. Can we have some one weld the magazine to the lower or we would have to weld it ourselves?

You have to weld it yourself or find someone with a manufacturers FFL according to HPD, if I remember the conversation I had with the sarge correctly. That was almost two years ago.

Can it be welded or it can be silver soldered on? I might have to try and go to HPD before I start building one.

No, it must be welded.

Try and be slick with silver solder and they will confiscate your firearm; possibly detain you if they are in a bad mood.

HPD IS USING STANDARDS SET BY THE ATF for permanently attaching extensions on barrels.







Silver solder is absorbed by the surrounding metal, resulting in a joint that is actually stronger than the metal being joined.
Silver solder melts at 1145-1300  as compared to  Aluminum which melts at 1200.


Ill need time to find it. There is a written letter from the Tech Branch that specifies a variety of ways to make it 'permanent', to include.

1100 deg silver solder.
4 equidistant tack welds
a continous weld of half the circumferance.
blind pin with the end of the pin welded over.

my personnel letter from ATF for use of Silver Solder!!

I doubt that the state laws, which are enforced by county law enforcement, are required to conform to theses promulgations by the BATFE.  the way i see it, the state can choose to follow the guidance provided by a federal agency, but ultimately they can require stricter procedures, which is what HPD seems to be requiring in this case.

therefore, although it may be federally okay to silver solder mags into magwells, i think that the state can choose to require a more permanent form of attachment.

Has anyone even seen silver solder?
That thing is strong, in fact it holds up better than or exceeds welding.

It's as if , you told someone in the 70s that carbon fibers are stronger than steel. People are misguided by the word solder. In fact the aluminum reciever may melt before the silver even puddles.

The State does not have a law nor any regulations about this matter. It's all an HPD internal decision with no legal bearings to any laws.

I was planning on ordering some alloy 5 solder. But I might have to speak with someone from HPD before I start on this AR pistol build. Cause I can't weld for shit. Lol unless someone can teach me. I'll pay for supplies and time.

I have no issues with your claims as to the strength of the silver solder.  rather, it seems that we keep coming back to the same topic, which is HPD's enforcement of the law based on HPD's interpretation of the law.  there's almost no point in arguing about how the world should or shouldn't be.  the fact of the matter is, until something mandates HPD to do it differently, HPD determines compliance.

Just a theory..

1. Buy a bullet button and install
2. Wrap tape around mag ( upper half of mag, so when inserted into mag well it doesn't jiggle) OR can apply a thin layer of epoxy putty/ steel stick (at 900 psi, I doubt it'll break from recoil) to fill in gap between mag well and mag. Or both!!!
3. Use epoxy or other strong GLUE on bullet button, the center part. (this should help keep the actual release mechanism from moving since glue can seep in between where the spring is and/or mate the moving part and non moving part of the bullet button )
4. use a tig or mig or 1100+ degree silver solder on bullet button where a "special tool" is needed to release a mag.
    ( I assume that filling in that hole WILL prevent the user of releasing the mag with or without any tools.)

Just my 2 cents...

Don't know if HPD will fail it or not, as others have stated, anything is possible with tools. to drill out a bullet button is not considered "readily" ... Right?

I do like the wrap around magazine and mag well part but seems a bit weird looking like those side charging 1911 and  glock pistols .

I had made sort of that suggestion previous, I suggested the mag release be welded and ground, which would, in all practicality, permanently disable a detachable magazine, and ruin the receiver if mag was attempted to be removed.  Someone, who talked to HPD firearms section, said that is not acceptable.  They stated the magazine must be obviously welded, full 360, don't know, but at least the long sides I'd wager.

2014 ... unacceptable

Made a spacer from aluminum, got rid of the spring, made mag release button from stainless steel and plug welded to mag release stud. There is no way the mag release could be depressed but HPD would not accept as non detachable magazine.

Woweeee!! Sorry for my bad input lol!!

Good luck on your pistol lower build!

Hope everything works out for ya!

Good job on that spacer though!! Looks top notch workmanship!! I was also thinking that but I would prob need a bench grinder and a drill press to come even close to yours. my earlier suggestion had items that were readily available to me lol!
