They’re not fully carbon fibre. The inner core of the barrel is steel, but it’s relatively thin. The layers of carbon fibre are then wrapped around it to get the compressive strength you’d need a lot of steel to achieve. So you get the same or better accuracy at a lower weight.
The tradeoff is the barrel loses a ton of thermal mass which means they heat up very quickly. Not so good for a combat rifle.
"On 23 June 1967, Rolls-Royce offered Lockheed the RB211-06 for the L-1011. The new engine was to be rated at 33,260 lbf (147,900 N) thrust and combined features of several engines then under development: the large high-power, high-bypass design from the RB207 and the triple-spool design of the RB203.[8] To this was added one new piece of technology, a fan stage built of a new carbon fibre material called Hyfil developed at the RAE Farnborough. "
They don’t make engines. In any case, carbon fiber is everywhere and your shockingly ignorant take on the material is impressively stupid in the age of instant information access.
It takes a lot to impress me, and you, sir and/or madam, have done so.
They’re getting pretty common. It’s a steel barrel sleeved in a cf wrap. They’re lightweight and strong and the cf insulates the barrel. It’s more common for hunting rifles where the barrel itself is exposed and more likely to burn the shooter through handling than an AR which will have a handguard.
My immersion is ruined by the mention of the material that cracks if someone sneezes too hard nearby.

Hm, better not fly in any airplane made in the last 60 years…

Thanks, I’ll avoid flying with Lockheed Martin.
