Hi, all! I've been scouring this site, google and even all of the sponsored links on the home page of AR-15.com in the hopes of not asking a redundant question. I've been wanting a CQB rifle and considered a 9mm carbine to keep simplicity a priority as far as ammo purchases go, considering my pistol is 9mm. I decided to go with what I WANT; a suppressed SBR in .300 Blk. It'll be a slow build considering my minuscule budget.

From my scouring, I know that I must have engraved on my rifle, my name, location and caliber. I thought  it may be a good idea to put the engraving on the upper to ease the difficulty of shipping a firearm (the lower) to get it engraved. I haven't seen any like that, and Orion's engraving service has set locations on the lower to choose from.

I settled on trying to find a company that sells striped lowers, engraved with .300Blk, that can engrave my sbr info as well before shipping. Are there any that offer this that are affordable? It's my understanding that multi is not acceptable as a caliber. True? I found this company that fully customizes lowers, which sounds intriguing, until you see the $250 price tag on a striped, forged lower. http://www.shadowopsweaponry.com/products/246-ar-15-stripped-lower-receiver-shdw-15-m4-in-stock-223-556-ar-15-lower-for-sale.aspx

Any help would be appreciated.

P.S. My slow build plan is AR pistol ( starting out engraved), to sbr, to suppressed. I'll be out for a few days, so any comments that go unanswered beyond tonight are not being ignored. I'll get back when I can. Thanks in advance and thanks for a great resource.

I would check the NFA section/Class 3. As far as the engraving I think it can be done on any lower, have you received your stamp yet? That would be my first priority as the ATF seems slow on returns right now. You can always build it as a pistol for now while you wait for the stamp.

I haven't read the actual regs. on the engraving. I have on other sections and read debates on this forum on the interpretation. All very confusing. I'll check that out, but am somewhat sure you have to have the intended caliber engraved on the lower (it will have a .300 barrel). Maybe I'm confused. I'll not go for the stamp until I've got the AR pistol eventually built. That way, I'll first have a functioning firearm, then save up for the stamp. By that time the only thing the stamp will be good for is to install a stock. Then the long clime to a suppressor and corresponding tax stamp. Thanks for the reply.

The upper can not be engraved. it has to be the lower with your name, or trusts name, and location. Never heard of needing to engrave the caliber before. My understanding, but it could have changed, is the form 1 had to say the specific caliber you were making. Such as a lower with "multi" engraved on it. On the form 1 you had to put 1 caliber.

But like the first guy said, check in the NFA section for the most up to date info.

It seems I was correct on all counts http://www.atf.gov/search/site/Sbr%20engraving?page=1  Caliber must be engraved, and all info can be on frame, receiver, barrel, or slide. Your choice. The only requirement for the lower is the serial number.

I don't know why more mfg. don't offer their lowers in more than just 5.56 or multi.

Link didn't work. I'm new to this. https://www.atf.gov/search/site/Sbr%20engraving?page=1

Third link down.

Perhaps having "multi" AND .300 is acceptable? Just found this one, I'll just have to find a local(ish) engraver for NFA requirements. If y'all find any other good options, please send a heads up. Thanks.  http://www.tacticalmachining.com/300-blackout-lower-receiver.html

Thank you! I've actually read this in my research. Again, this limits my selection in lowers as most are engraved with multi or 5.56. I did find an inexpensive lower marked in .300, but it'd be nice to have more choices in logos and to have it engraved with other info before shipping. You know, one stop shopping.

There are 100s of 300 Blackout SBRs posted on this site. I have yet to see one that was engraved with "300 Blackout" . If it bothers you that much,  buy a multi-marked lower and have an extra line added stating "300 BLK".














































 

Free if you know how to get and use Quicken Willmaker. No fingerprints.  No LEO sign-off.  Faster to process.

 











 

Thank you very much! Wisdom speaks volumes! One more question; when you get your sbr engraved, does it not destroy the anodized coating? What do you do about that?

Aluma-black

 

Ah, very cool. Thanks again. Very helpful!

So putting a .22 upper on an SBR lower marked .300 blk isn't an issue?

Nope, use whatever upper you want on your lower...

 

I wish you the best of luck.

As I'm going through this right now. The lower does not need any additional info engraved on it pertaining to caliber. Just your name ( or trust) city and state. You do have to give a single one on the form 1. Once submitted and approved, you may swap uppers as you please but the rifle should be able to return to the caliber you specified. If you'd like to change it, you may submitt an updated caliber/ barrel length change to the ATF. (Obviously you'd keep it another short barrel as you paid the tax.
