AR lowers WITHOUT caliber designation?

Mgderf
I recently saw for sale, some AR lowers being offered by a relatively new manufacturer (of lowers anyway).

This is a well established machining business, who has started turning out lowers in an attempt to keep the workers and machinery working. Most of their business to date has been for the automotive industry.

Anyway, they have turned out some AR15 lower receivers that have NO caliber designation on them.

FFL dealer says he contacted the ATF and they told him that as long as the caliber was denoted SOMEWHERE on the gun, you would remain legal>

I was under the impression that the receiver had to be marked with a caliber.

These are BEAUTIFUL receivers, with a great looking finish, but no markings has me wondering.

Can anyone shed some light on this subject?

Thank you!

    How can you mark a caliber on something that does not have a caliber? Since you can build the standard AR-15 lower into at least 50 reasonably common calibers what caliber would you like it marked?

    So what if you have a lower marked .223 and yet have a different caliber upper on it? What would happen if someone decided to put the caliber listed on the side of the gun vs what caliber the gun is actually in?

    Many companies are now marking lowers as "mulit-cal" or similar.

    I knew I was forgetting something simple (tired tonight). That is exactly right, there is no caliber requirement nor could there really be.

    I've seen the lowers marked "Multi" and I've also seen them marked with a double designation .223/5.56, but this is the first time I've seen one WITHOUT a marking.

    It needs to be stamped with a serial number and the firm that manufactured it. Caliber is not in the regulations because in the case of a bare receiver, the caliber cannot be determined until a barrel is installed.

    Actually I saw them at the 1500 gun show in Indianapolis , In. a couple of weeks ago.

    The company is called Delaware Machinery in Muncie, In.

    If you'd like, pm me and I'll get you the contact info.

    IIRC, the caliber is marked on the BARREL of most of my rifles and shotguns- and revolvers.

    Here is a bright light for you. Look at the T/C recivers. Do they have a caliber on them? No they don't. So where ever your getting the info about lowers for AR's needing a caliber is full of caca.

    Interesting. I have 2 Rock River lowers both marked 223/556. One has a RRA 223/556 upper with no markings at all. The other one I have a Tactical Solutions 22 LR upper that is clearly marked. It is a little un-nerving that RRA doesn't mark their uppers.

    True, Mauser's either for that matter. And, it should be the same with AR's. The caliber should be marked on the barrel. If you marked it on the upper then it would have to be wiped off/struck out and re-marked with new caliber. Better to do it on the barrel just like all the rest.

    As someone said you can put all kinds of calibers into one nowadays and someone will lose a face if the wrong round can chamber.
