School me on barrels with integrated suppressors, 9mm

danb · Aug 17, 2018

For various reasons mostly to do with Maryland I'm not really interested in SBR-ing my 9 mm AR then attaching suppressor. Although an 8" barrel is plenty for 9mm since velocity maxes out about 9", I dont want to deal with douchey MD rules. I have a 9mm pistol with brace, not going that route either. 23" of barrel plus supressor is a bit ... long... for a 9mm.

So, been contemplating a 9mm barrel (really: upper) with dedicated supressor. So school me. My first thought- 9mm is really dirty. Or so it seems. Arent these a PITA to clean? My second question is obviously- can I hunt chupacabra in Montgomery County with this? First things first tho.

First world problems, I know.

They work very well depending on weather you are looking for like a SD type where the barrel is ported to drop the velocity of a super sonic round, To subsonic. I find if you go with a 124 bullet weight or higher they for the most part are extremely quiet. Yes they do run dirty. But invest in 2 things. 1 a ultrasonic cleaner. 2 take and modify a battery post cleaner and mount it in a tube. Use it to clean the OD of ur barrel. Works like a charm! Are they deadly? Yes and extremely quiet. It isn't hateful to do a AR15 9mm that mimics the mp5 SD.

I have an ultrasonic cleaner. I assume you mean for the baffles, since the whole integrated barrel/ upper would not fit?

Well on the 1 I have I kept it a pistol with a brace. And have a removable suppressor. So the suppressor goes in the ultrasonic cleaner. The tool I talked about I use to clean the OD of the barrel. My barrel is about 6 1/2 " long.

If you take a look at the NFA picture thread, I believe, you'll see one member who has the Spikes Brown Recluse integral 9mm upper. Would be a good one to ask. Think his name is SCARCQB or similar

If I were going to replace my barrel and go the integrated/perma-attach route, this is what I'd start with:

My pre-ban 9mm SBR is due for a refresh, and I'll have a spare 9mm suppressor, so I might give this a try in a year or two.

I use a an upper with a 5" barrel with 3/4-10 threads. I screw a CAC 9 can onto it and a round free float guard. SD pdw brace and all is well. Barrel made by TROS. Can also fits my MAC. Just as good as an SBR and one stamp.

I went a similar rout, instead opting for a 5" ADCO bbl with 13.5x1LH (European) thread. My Surefire Ryder 9 Ti came available with that piston. It tends to keep the can screwed on better.

SB PDW brace on a QC-10 MP-5 AR lower.

Hornady makes one big enough for needs I think:

That is a short barrel. Are you getting subsonic out of standard 115gr ammo out of that?

Not with the +P stuff, but with bulk ammo, probably:

I think it would be marginal once you tacked the suppressor on there. But you'd be running it as short as it would go, which is something.

School me on barrels with integrated suppressors, 9mm
