Anyone know of a pencil profile 12.5 barrel in 5.56? Trying to piece together a light weight build, but can’t find any pencil 12.5’s.

Faxon’s Gunner barrel is supposed to be a hybrid that might fit your needs.

You might have to go the 11.5 pin and weld route if you're dead set on a pencil barrel. Our dumb state is the only one with a hard on for 12.5 barrels.

I think you are right, or have a 14.5 cut down. I have an 11.5 upper that I replaced with a 9” 300bo upper on my pistol that needs to be p/w, but I really want to see how light I can go on a 12.5 with out spending big money.

A Kineti-Tec muzzle device/blast director combo with the underlying muzzle device pin/welded to a 10.5" barrel will bring the barrel length up to 12.25". So if you want as light as possible find a 10.5" pencil and do that.

Isn't it just over 12", not 12.5"?  I would think that since a 14.5 with a permanent A2X flash hider is 16.1", then a 10.5" with an A2X is going to be 12.1"

Some 11.5 barrels might actually be lighter than 10.5's though.

Triarc's Track 2.0 barrel is probably as close as you can get:
https://triarcsystems.com/product/12-5-track-2-0-barrel/

Be advised it is a midlength and not carbine gas.

the triarc 12.5 is 1.45lbs.
criterion ultralight 12.5 is 1.4
criterion CORE 12.5 is 1.45
centurion 12.5 is 1.34 (thats out of stock at the moment)

i ordered the criterion core 12.5 and it arrives tomorrow. i fed into the claims about it and it looks like it makes sense, the reputation is great, and its chrome lined.

Im leaning towards triarc or criterion.

I appreciate everyone who suggested going 10.5 and pinning, but I don’t want to pin anything to this upper because I don’t have a dedicated can for it yet.

I thought most light/pencil barrels were not for silencer use...I've been told that they move a lot more and the chance of a baffle strike is greater plus a degradation in accuracy.  Is that bad info?

Eh, greater chance of POI deflection due to weight on the end. But if the POI change is repeatable, the accuracy is relative. Baffle strike risk is moreso due to non-concentric threads or mount system

Frankly, though I could be wrong, I would expect a pencil barrel with a can to be more "accurate" due to the change in harmonics. That said it's pretty hard to shoot farther than 100yrds in this state. I don't really lose sleep over it.

I was posting to clarify this. So TWELVE inch us DEFINITELY a no-go.
The minimum barrel must be 12.5 INCHES.

I this correct?

Or are we just using 12.5" as a bogey to ENSURE that we are well over the 12" minimum?

Can someone please clarify (or welcoming opinions).

12 is fine. 12.5 is the “safe zone” most manufacturers go with.

12” barrel, 26” overall length.

12 is fine (as it’s not “less than 12 inches” CT Statute). As long as it’s measured per the ATF guidelines. It’s not quite as easy as putting a tape measure on the outside of the barrel.

Less than 12 and it’s NOT an other it’s an illegal pistol and falls under the CT AWB.

12.5 is just an industry standard. 10.3/5, 11.5, 12.5, 13.7, 14.5, 14.7 and 16 are just a lot of what’s available.

I’ve seen one 12.0 inch barrel in 300BO, and I’d be hesitant until I measured it myself, for what the actual length is down the bore. Could be over, could be under. Could be 12.0 exactly.

Thank you for the quick reply.  I didn't even consider that option.  So pistol configuration is barrel less than 12" and pistol brace?

Any barrel length without a foregrip, and with an arm brace. It has the benefit of easier interstate transit if that's something you care about.

Incorrect, unless the piston design uses some sort of captured buffer system in the upper and a non-traditonal BCG they require a standard AR buffer system. I personally have a Taiwanese T91 12.5" upper on a pre-ban pistol lower. In order to have a no buffer tube and normal functionality you'd need something like a MCX upper and pic rail stock/brace adapter ($$$$$ but very nice), or if you want a shorter buffer tube, there are kits from the likes of Deadfoot (also $$$$) but I don't see the allure there.

I did something a little unique and hard to notice. I used the LWRC UCIW compact buffer system and modified the SBa3 to fit (cut it shorter) the tube. Took about an inch off compared to a regular carbine setup.

There are some specific piston driven uppers (Sig MCX and Brownells BRN-180)  that don't require buffer tubes, but most other piston uppers do require them.  If you're under 26" you need an AOW stamp, which you can get e-filing a form 1.  If you put a folding brace on your overall length is measured with it folded not extended.

AOW stamp is only needed if the firearm is <26" AND has a vertical grip

Also, if you are Form 1ing an AOW, the stamp cost is $200, not $5 like when you buy an AOW direct from an FFL/SOT
