I had mostly forgotten I'd even applied. Submission date was 2016-7-8. Just got my notice today.

Now I need to find a good SBR upper.

Definitely the way to do it, submit and forget! I'm assuming this is for an AR - any thoughts on barrel length? I currently have 10.5, 11.5, and 14.5 - with the 11.5" Colt my favorite with my M4SD-II from Griffin. 10.5" is LMT and has run flawlessly for years.

I'm thinking 10.5. Maybe DD MK18 or LMT. I have 2 LMT MRP rifles and they have been great.

Did you get a stamp? or did you get a completed and approved form 1?

I have been super happy with my BCM 11.5" KMR, its slick and super light.

I guess I'm not sure of the difference. They sent me an email notifying me that my submission status was changed to APPROVED and included a PDF attachment of my application with a $200 stamp affixed to it.

If you have the patience or the tools, building it yourself has always been the way to go. However, with how soft the AR market is right now, the world is certainly your oyster. would love to see some pics when it's completed!

What barrel length did you specify in your application?
I believe you have to build and retain that configuration before you can build anything else. I was told that you can have an unlimited number of different setups as long as, on demand, you can return it to the configuration that ATF approved.

Any more experienced people want to weigh in?

Agreed. I added a suppressor to mine as well.

I specified 10.3" in the application. I must have had a particular upper in mind when I put that in there, but by now I have certainly forgotten.

10.3" would probably mean a DD Mk18.

I am glad go hear your stamp has been approved! I sent my application in 3 days after you. I will be one of the last of the pre- 41f apps to be approved. My app went "pending research" for 3 weeks while they figured out the serial number.

IANAL, but my understanding is that you can have any number of uppers, so long as they are the same length or longer as what is specified on the form. My understanding is that specifying a 10" sbr and then affixing a 4" 9mm barrel to it is a no-no. But again, IANAL.

Ive always heard you can put any length upper ( or caliber) on it as long as you can put it back to original.

This is correct.

I love my 8" 300 blackout.

Congrats on the stamp approval! Mine was approved in February and I just last night finished my SBR upper build!

Now I just have to get it signed in. Unfortunately I most likely won't be able to get to it for two weeks.

The upper build is a Faxon 10.5" pencil weight barrel, Superlative Arms adjustable bleed off gas block, Geisselle dessert dirt ambi charging handle, V7 Weapons System titanium barrel nut, Yankee Hill Manufacturing Phantom QD suppressor mount flash hider, BCM 9" KMR Alpha rail, PSA premium BCG, Anderson manufacturering upper with MagPul MOE FDE BUIS and a Primary Arms 2.5X ACSS reticle prismatic scope.

I have to say one thing about the scope, it is crystal clear! It was $199.95 and I believe it is quite the bargain.

I'm hoping that the barrel preforms as good as it looks. The finish on it is outstanding. I looked it over real good before installing it and I couldn't find a flaw.

The whole package is lightweight and solid. I can't wait to get out and shoot it, zero the BUIS and scope and get the gas block adjusted. I want to see how this thing runs!

To to OP, have fun with your new SBR. Also you can put any length upper on it as long as you are able to configure it back to the original form of whatever is on the paperwork.

This is correct.

so if I have a stamp for a 10.5" .556 build, I can put aN 8" .330 BO upper on it as long as I have the original upper (or a length/caliber the same) that'll bring it back to its original configuration?
