Why No Integrally Suppressed 300 Blackout Bullpups?

[Gary H]

The obvious answer is that there isn’t a market for this combination.

I like bullpups and I don’t like the hassle of a SBR. Some of the problems associated with silenced bullpups might best be addressed with an integral design. A bullpup’s issue with blowback of gas when silenced and problems with reliable function while shooting subsonic ammunition could be addressed with an integral design and a suppressor tax stamp is an easier and likely faster turnaround vs getting an SBR and Silencer.

That said, bullpups aren’t popular. Other than an inferior trigger when compared to a good AR trigger, I am in the minority and like bullpups. Does anybody else see a home defense advantage to an integrally suppressed 300 Blackout bullpup? I assume that we still have the limitation of moving from state to state with an NFA item.

The inherent assumption is that ATF will cooperate with the "integral design and suppressor tax stamp" thingy. I think it would likely be pushed to an agency only product line that would limit what is already a small market. That would greatly increase the price demanded since the small market would have to absorb all of the development expense.

So, the financial risk far exceeds benefit. Makes sense.

And when you think about it, why don't we see more integrally suppressed bullpups or rifles in general in other calibers? It isn't just a .300 BO thing.

One of the main hassles is that it isn't just your silencer that is Form 4, but the whole rifle because it is integrally suppressed. If you are able to just able an upper, then you have an entire upper that is Form 4, which is less of a hassle.

One problem you're gonna have is you might need a gas mask to deal with the gas to the face. Although you may be able to deal with that some by shielding the action and sending the brass out the front like a Styer AUG.
However some of the justification you are using is suspect.
If you send in multiple form 4s to buy a SBR and a suppressor at the same time, they'll come back about the same time if not the same day.
If you form 4 the suppressor and form 1 a lower receiver to assemble your SBR the form 1 will typically come back in 30 to 90 days form 4s take 6 months or more.
As for traveling with NFA items it's not as big of hassle as folks make it out to be for the suppressor you just need to make sure that they're legal to possess in the state your heading to.
SBRs require a form be filled out to notify the ATF but the form is good for a year and you can just fill one out for several states.

If your using 300 BO primarily as a suppressed subsonic gun then you don't really need the longer barrel to get the common heavy subsonic bullets to the usual ~1050 fps. This reduces the advantage of the bull-pup design in this application.

Also bull-pups are ugly as sin and should be avoided at all times, but I digress...

I am not real sure there are integrally suppressed Bullpups in any caliber..

The only advantage of a bullpup is in close quarters, and in this instance, being able to avoid the SBR process. The main thing that is ugly about bullpups is their triggers. The primary challenge would be a reduction of gas with the silencer and perhaps convincing the ATF to allow sales with a suppressor stamp. If successful, a maneuverable, suppressed, subsonic rifle for home defense would be functionally attractive, but expensive.

Just how much are you willing to spend to avoid the $200 stamp for a SBR lower.
And mind you now you're stuck with one caliber in one configuration.
With my SBR lower I can put an 8" 300 BO upper or my 12.5" 5.56 on it and I can even use the same suppressor if I want, I can even run my dedicated 9" 22LR upper or for that matter I can run a 20" precision upper on it.

Not an issue plenty of integrals out there, you could probably get Ecco machine to make an integrated barrel for a Tavor or AUG.

Have you given any thought to where you're placing your other hand? That handguard is gonna get hot pretty fast with the suppressor tucked
