Who builds custom chambered AR-15 barrels?

[Togeneral99]

Looking to build a 16 or 18" AR-15 in a medium contour weight with a 7mm TCU chambering, but I'm having difficulty finding a barrel manufacturer that advertises either this chambering or a custom chambering.

Do you guys know of any?

Thanks in advance

Krieger might; it will be a loooonnnngggg wait though if they do.

Not a barrel maker, but Compass Lake may be able to take care of you. I've talked to them about a couple custom calibers and they seemed willing.

I suspect that part of the difficulty in find an AR-15 barrel in 7 TCU is that the mag constraint of 2.260" as max OAL is too short.
Most bullets will be seated such that ogive is at or below neck/shoulder.

Would pretty much be a single shot, which limits appeal for an AR pretty heavily.

From what I've seen so far with 120 gr bullets you are right, although SSK industries offers an entire upper, but I have no idea what other modifications they may have made. Also the 7-30 waters bullets would work very well for overall length due to their flat nose for safety reasons in a tubular mag.
