Carbon Fiber TL3 prefit question

[blksno]

I'm putting together an ultralight hunting system and I'm looking for an 18-20" carbon fiber pipe to use with my BigHorn TL3 and Q SideChick chassis.

The one hang up I'm coming across is that the side chick will only accept a 1.200 shank...and most carbon fiber prefit a I'm coming across are 1.230-1.250 shank.

I'm open to caliber really, but I'd prefer an 18" shouldered prefit and I'm drawing a blank.

Thoughts??

Proof research sendero’s are 1.200 at the shank. And the have tl3 prefits. My question is how did you get the side chick rail to mount on the tl3?

I haven't been able to track down an 18" Proof CF prefit. My understanding was 22"+ only...or perhaps 20" 6.5 Creed. I'd prefer an 18

And here's the post regarding my top rail...
It's a wicked little set up.

Gunsmithing - BIGHORN TL3 in a SideChick Chassis

I'm working on getting a custom rail made to bridge the Q Side Chick hand guard, to the Bighorn TL3 action. I've talked with Q and got them to release the CAD file, but understandably they don't have the machine time to make me a one-off. I got the folks at Bighorn to modify the CAD file for...

Just do a custom prefit, buy a proof carbon fiber blank in the length you’d like and have someone chamber it for the TL3. I’ve use LRI in the past, great work and fast then around 2-3 weeks.

If you want a one stop shop online ordering use someone like PVA or straight jacket.

Get a blank and have a smith spin one for you if you really want an 18" 6.5CM versus say 22" 6.5PRC

Awfully pricey option for 2" of barrel which only weighs 1oz more (22" versus 20")

I would save some money and grab a 20in 6.5 creedmoor prefit.

If you are set on 18", a thinner profile SS barrel will weigh nearly the same. My Bartlein 2b 18" is very very close in weight and shoots as good as any of my proof carbon barrels (I have 8 carbons). The true weight savings happens from 20in and longer. I even talked to a guy at proof trying to verify and he said weight difference is negligible.
Not as cool as a carbon, but accuracy and balance won't be a huge difference.

But can a 2b use a brake/suppressor

Yes. Was taking prairie dogs out to 350yds regularly with a dakota 3.0 varminter can.
