Pro/Carbine barrel threads

[ZZ rai]

do the P/C have the same thread as A-5, prolite, and F-4?

[PBKorin]

Yes.

Any barrel with those threads will fit any of those markers.

[Caleb98]

do the P/C have the same thread as A-5, prolite, and F-4?
yes they all have the same threads.....BUT...when using an F4 barrel you must use the larger bore barrels because you remember that in the carbines the front bolt actually travels into the barrel, and small bore F4 barrels like the JJ ceramic will cause the front bolt to lodge in the barrel, but the aci zero gravity works perfect. GO AHEAD ASK ME HOW I KNOW......DOH!!!!:rolleyes:
