Yes I have one of those in 5.56/.223, but I also have a 10.5" & 14" not pinned barrels for SBR in 300 BLK and yes I have the stamp of approval from the BATF along with the lower engravings as required. I also have a suppressor for the 300 BLK with the stamp. The suppressor is removal, and not pinned.

I'm looking into a SBR and Suppressor myself.

Yep that's what I did also. Makes it easy to pass to another with it too.

New addition to my semi finished AR build.

Phase 5 Tactical BAD Lever, It replaces the bolt release unlike the one's Magpul has out. Which tend to work loose after heavy use.

[Roverron]

Nice! I have Magpul and Troy BAD levers on a some of mine. But the phase 5 looks very nice

You can also run shorter barrels ... ~12" with mid-length gas, ~10 with carbine gas, or ~8 with pistol gas ... just by setting up a lower with a pistol buffer.

Here's my 12" Wilson Combat in 6.8SPC:

If it was going to be a 308 build, I'd be interested. I've seen several online videos even one from Brownells. The shared experience might add something however.

I'm a qualified "in".

Ive never considered a pistol but this was from a friend who had sent a letter to BATF:

This refers to your letter of xxxxxxxxxx, in which you inquire
about the legality of manufacturing a handgun which utilizes a rifle
type receiver.

26 U.S.C. Chapter 53 # 5845(a)(4), the National Firearms Act (NFA),
defines the term "firearm" to include a weapon made from a rifle if
such weapon as modified has an overall length of less than 26 inches
or a barrel or barrels of less than 16 inches in length.

Utilizing the receiver of an existing rifle for the purposes of
manufacturing a handgun would constitute the making of a firearm as
defined above. Individuals desiring to make such a firearm must first
submit an ATF Form 1, Application To Make And Register a Firearm and
pay the applicable $200 making tax.

If an individual were to obtain a rifle type receiver that had not
previously been utilized in the assembly of a rifle, a handgun could be
made and not be subject to the provisions of the NFA. Verification
must be obtained from the manufacturer of the receiver to establish
its authenticity.

We trust the foregoing has been responsive to your inquiry. If we may
be of any further assistance, please contact us.

Sincerely your,
(signed)
M. Owen, Jr.
Chief, Firearms Technology Branch

and there's this letter I've seen:

-------------------------------------------
So, from this Im assuming if the lower was registered originally as a Rifle, then Form 1 and $$$ is required to have it re-registered as a pistol lower. Does it require engraving on the lower to show as a pistol or ?? However, if you originally purchased the lower as a Pistol lower, then a Form 1 is Not required.

Is that correct? I might have to check into building one. cool looking pistol!

AR receivers are not recorded on forms 4473 as "rifles", they are simply "receivers".

You can build your receiver as a rifle or a pistol. Technically speaking, once it has been built into a rifle with a buttstock and upper attached it is only and forever a rifle unless you go the form 1 route to convert it to a pistol.

The exception is as your second ATF letter states ... if you buy a complete lower receiver with a buttstock attached you are allowed to remove the buttstock and replace it with a pistol buffer ... but once that complete lower is assembled with an upper it is forever a rifle (except form 1, yada, yada).
