Thanks, DeRico, but I'm looking for info on SBRs.

^ This right here and what JG stated above!

No worries, SBR’s are great too. I own one and don’t use it for home defense.

I had one in .300blk suppressed and I tell you that I’d choose my pistol first rather than my SBR.

Enough ranting, I’d recommend 8”-10.5”, 5.56mm 62gr green tip or 77gr OTM(for the 10.5”). I know it’s expensive but the Surefire RC3 would be the best option for suppressor, next in line would be the Dead Air Sierra 5. Both are lightweight.

Personally I'd trust a light, short, carbine with good terminal ballistics like a 5.56 or 300blk SBR over something that I'm likely to short shuck in the heat of the moment. And also, since I'm accountable for every bullet that leaves the gun, I'm not keen on wide spread, low cap, high recoiling shotguns.

The 5.56 will blow through your walls and possibly into your neighbors. With a center fire rifle cartridge you have to be precise in your aim. Shotgun, not so much plus you get the knock down punch factor.

If you live in a city with other houses nearby, I would be concerned about 300 Hammering a baby in another house. Sheetrock won’t do much to stop hog blaster SBR’s most folks have. If you live in the country, disregard.

1. What is the typical drywall penetration of a 12ga 00 - #4 buckshot vs 5.56?
2. Do you think you don't have to aim with a shotgun? What happens to pellets that don't hit your target? I think your answer might change after you read about #1.

Again, I must stress, you are responsible for every bullet that leaves your gun. A wide spread is not something your neighbors would appreciate.

If it helps: 12ga flitecontrol at 6:20, AR starts at 7:20. As always ammunition choice matters a lot, but 5.56 tends to yaw and break apart after a couple layers of drywall. Pay attention to the VMAX and 77gr loads especially.

1. YouTube video...take that with a grain of salt.
2. I never said you don't have to aim with a shotgun, just don't have be a precise as I would have to be with a 5.56 rifle. How many times do you have to fire the 5.56 to stop the the threat? Shotgun is probably going to knock the perp on his arse after the first "well placed" shot.

I've done two now, and am happy with both. The first is a 12" barrel 5.56mm, no suppressor, using Palmetto State parts. That's just plain fun to shoot and makes a damn good truck gun.

The second is an 8" barrel, 45acp (because I like 45acp . . . a LOT), built on CMMG parts. Uses Glock magazines. Waiting on my Rugged Obsidian suppressor to get approved for it. This is intended as a home defense gun, as I'm not worried about 45 going through the brick walls into neighbors homes.

Not to derail the thread, and i didn't want to ask this question here, but there is so much convoluted info on the internet now, i figured i may as well.

Do you have to have a Tax Stamp to own a SBR?

Short answer: in most cases, yes

Under what circumstances is a tax stamp not needed for an SBR?

there are none that I know of.

I have built 4 sbrs, 5.56/7.62x39/.300 bo/.17hmr, they all have a purpose and were built to carry in a sxs here at the ranch.

if it will be a bedside home defense gun then just buy a complete upper (I use the side charging) from psa or bear creek, mine are all 10.5" except the 7.62x39 is an 11".

all are or will be suppressed, waiting on the last can to be approved now (I screwed up and did the trust thing).

these are the 7.62 and .300 bo, saving for a thermal for the 7.62 to finish it off.




this is the 5.56 I used

Thanks for the replies fella's.

One more question, and I'm out, i guess it's to say that I should go buy a complete SBR upper and do the Tax Stamp all at once?

A short barreled upper is not restricted as it can also be used in a pistol configuration.

The Tax Stamp is for the lower receiver (serial numbered part), however when you submit your application for it, you have to list a caliber, barrel length and overall length.

Once approved though, you can use that lower with any upper.

^ nothing wrong with that approach. Just don’t store the lower with the upper (constructive intent).

If its transferred to you tax free on a form 5.

that is what I had to do for my .17hmr and .300bo, neither were on the list when I filled out the info so just put them down as 7.62x39.

pick your favorite lower you don't ever intend to sell and use it for the stamp, I bought full uppers since it was cheaper and easier overall than building them (mine are built to haul around in a sxs mainly).
