Varies by department. Mostly 16" carbines or 10-11" SBRs. Mostly if not always 556. Rarely select fire surprisingly. Seen a lot of them do qualifications on 16-18" semi autos.Curious, what length do the Leo's carry in their vehicles nowadays? I know they're using an AR variant, I'm just curious to the types and lengths that are being used as opposed to the traditional guns that were used in the past. I know sub guns primarily are swat and other units and shotguns were wayback when but…
My 9 inches burn if she's really tight.My experience has been 8" works just fine. And the .300blk achieves complete burn at 9" and was designed for such length barrel.
Edited, my info may be wrong.
Are you referring to the one I built the upper for? That was a BA premium SS 7.5" Hansen profile.. a rare barrel. they don't make anymore. I really liked that build..had a cool fortis rail if I remember correctly. the only reason to shoot subs is if you're running suppressed anyway, and with a can it probably would have had enough back pressure to run just fine. Did you get rid of it?I used to keep one under my bed. Great HD setup with SD ammo. It cycled everything but subs reliably but I already knew that before I built it. Only thing that has pushed me away from .300blk is ammo price and availability.
I vote YES! on .300 Blackout pistolsI have heard lots of good things about these type of pistols and some bad. Anywhere to reliability to upcoming possible legal constraints, I have a chance to get a real nice one but I am on the fence as to whether I should. I already have a PDW set up for home defense (9mm) but I thought it would be better to have something with a little more ooomph.
What are your thoughts guys?
Thanks
Please see above, selling stuff here can be hard…Shooting my blackout pistols reminds me of when I was 12 or 13, with my 10-22 and a pocket full of cci mini mags. Fun. If you don't reload, you should, 300 blk is cheap to reload. And it's really fun to unload. My mindset is to get whatever I'm interested in and if I don't like it, I'll sell it. Just bought another safe, evidently I'm not good at selling.
That was my understanding as well. A 9" barrel was supposed to be it.Well even still I edited my previous post. I swear I have read and heard many times that .300blk was DESIGNED to function and perform optimally in short barrels such as pistols. But when I'm wrong, I'm the first to admit it. Luckily it happens very rarely.
Wow that would certainly be a small barrel for that caliber..This thread has me looking at this little guy again! Currently oos however! Some day I'll do it!

Just a wee bit shorter than the Sig Rattler at 5.5". KAK used to make a 6" barrel with the 1/5 twist. If they still had that, I'd prefer that one. This with the 5" can I'd put on it would still be quite short. It would be subsonic only if I did do.Wow that would certainly be a small barrel for that caliber..
A 9" barrel definitely is it if you want it for short range, especially suppressed. For the most flexibility, AAC (the developer of the 300 AAC/300 BLK cartridge) designed a 14.5" SBR. It's tuned to run everything from 110 gr to 220 gr without adjustment. I've shot one a lot and it's fantastic. It runs everything fine with or without a suppressor. 14.5 is the length where the returns on increased barrel length start to diminish rapidly. This why it is "optimal" for both subsonic and supersonic. For just subsonic, 8 to 10 inches should be fine. If you go any shorter than 8, you may need to tune it carefully and it may shorten the life of some suppressors. But to be clear, a 9" barrel can be a very good choice.That was my understanding as well. A 9" barrel was supposed to be it.
All of my 14.5" are 5.56 and I don't see that changing, the only reason I'd do a .300 BO is for the 9" barrel. If I were to seek more horsepower that a 5.56 out of a 14.5-16" barrel it would not be .300 BO.A 9" barrel definitely is it if you want it for short range, especially suppressed.

Since the other choice I have is 12.5 then I guess that would end up being the best overall one to get?A 9" barrel definitely is it if you want it for short range, especially suppressed.
