How to legally build a Glock compatible pistol using a Polymer80 frame in Michigan

I wrote about this also in my post about starting a Polymer80 build but thought I would break it out for people who just need to find out about this one thing – how to legally build a Glock compatible pistol using a Polymer80 frame in the state of Michigan.

For those of us in Michigan, we know we have some additional laws on pistols that other states do not. To be honest, before I started this project I wasn’t really sure that I could even do this legally so I started researching.

Before I go further, I’d better give the legal disclaimer: I am not a lawyer and this is not legal advice. The procedure I am going to outline is for a non concealed carry permit holders. I do not have a Concealed Pistol License (CPL) and my understanding is that the process is different and easier if you do have a CPL. Making registrations easier is yet another reason that I want to get my CPL this year.

Let’s Get Into The Details

To do this legally in the state of Michigan is actually pretty straightforward. First, you need to go to your local Sheriff and get a pistol purchase permit. I called first to make sure I understood where to go, what I needed to bring and so forth. All they wanted was my drivers license at this point and they did not want me to bring in any thing having to do with the pistol and definitely not the pistol itself.  This is not like the old days when you had to take your pistol in for inspection – you are just picking up forms after they run a background check on you.

The lady I talked to on the phone at the sheriff’s department was very helpful but she wasn’t sure what to do until I told her I was building from an 80% lower. When I asked her what I should do in regards to the manufacturer, model and serial number she recommended that I contact the Michigan State Police firearm records division and for your reference, their number is 517-241-1917

The folks I talked to there on two separate occasions, instructed me to complete the purchase permit form with the maker as “SELF-ASSEMBLED”, model as “NONE” and serial number as “NONE”. I filled out the rest of the information in regards to the caliber, number of shots, barrel length, overall length and whatnot same as always. I then mailed the forms in to the address at the bottom of the form.

My local Sheriff’s department was very helpful and recommended that I wait until I was done with the build because the purchase permit was only valid for 30 days. I confirmed this with the Michigan State Police Firearms Records division and they too were very happy to help.

I wrote this post to get rid of the fear uncertainty and doubt that some people seem to have. You can do this. To be safe, I would urge someone from Michigan to do their homework and confirm my findings so you can legally enjoy your resulting pistols just like I plan to.

ATF letter stating that the Magpul AFG is legal for use on AR pistols

Folks, here is an ATF letter saying that an angled foregrip (AFG), such as Magpul’s models, can be used on an AR pistol.  This is the first time someone shared a definitive letter with me vs. hearsay.

12/14/2014 Update:  Here are scanned images of two different ATF letters saying AFGs can be used on AR pistols because they are not considered vertical grips:

atf-afg

This is a second letter wherein they answer a number of good questions about AR pistols in general.  On page three is another comment that the AFG is allowed:

AR_Pistol_1 AR_Pistol_2 AR_Pistol_3

The reason this matters is that a vertical foregrip is not legal without first registering the pistol as an “any other weapon” or AOW.  I recommend people print and keep copies of letters just in case they need to show someone that some aspect of a weapon was “approved” by the ATF at some point.  Just bear in mind that ATF letters are not absolutes but it helps to have them handy if asked.  A state or local government may have their own more restrictive regulations as well so this may not mean AFGs are legal for everyone everywhere.
