11.5" reduced gas barrel recommendations?

I know this has been discussed plenty in the past, but things change. Looking to build a 11.5 suppressor host upper. Specifically using my old Specwar K.

My knee jerk would be a Sionics RGP or something from Clint. Would like at least “rack grade” accuracy, but better would be preferred. Just sayin. Not expecting a foot long precision rifle.

So chime in. What’s new and exciting in the market. Should I just stick with tried and true? Open to suggestions, but I am in Tucson for a bit longer, and Sionics is just across town.

I’d recommend Sionics. I went with the suppressor dedicated barrel and I’ve been very happy with it. Pairing it with a LMT E-carrier and the newer BCM CH has been a phenomenal set-up. Accuracy has always been solid from my Sionics barrels, the 11.5 has maintained that experience.

This. I don’t see a reason not to buy Sionics, especially since they are local to you. My 16” Sionics upper is my favorite hands down and is perfectly gassed and I run it suppressed and unsuppressed.

I’m here temporarily for a job. Next up Nevada, then Missouri.

I’ve been in Tucson for a bit but haven’t made the time to see if I can get over there. I honestly don’t even know if Sionics has a public storefront. I know he wasn’t an owner, but Sionics kinda equals Will to me. It might be a little depressing to go in.

Sionics has been the default recommendation for a smaller gas port for the ten years I’ve visited this forum. If suppressed only, the ERGP.

I got a BRT suppressed only barrel with a EXtended Carbine gas port. A little longer than Carbine and shorter than Midlength. I like it.

The reality is that a lot of manufacturers have followed the smaller gas port trend in the last five years.

You could also get something like a Colt SOCOM barrel and cut it down. I use a 13” Colt pencil barrel like that. No adjustment to gas port size = lean. Suppressed, ejection was at 3:00 with a rifle buffer and 3-4:00 with an A5H2.

Any barrel with a brt tube will work too. I have one on a bcm 11.5 and it made a huge difference.

My Sionics 11.5 RGP doesn’t pass the 5.55mm bore gauge. I don’t have any smaller pin gauges to see how tight it is, and it’s never given me issues.

All my Colts pass the gauge. (i.e. the 5.55mm pin passes through the bore completely)

If you have a favorite barrel already, the BRT tube is worth the investment.
