What is the CMMG - PS90 10.4 Barrel 4150CMV CL 1:9 5.7x28?

One of the iconic platforms chambered in the 5.7x28mm FN cartridge is the FN P90, and the company offers a non-NFA, semi-automatic variant for commercial sale in the US. However, this long-barreled model just doesn't look right, which makes this platform a candidate for an NFA-regulated SBR build. Enter CMMG and its PS90 barrel. The CMMG PS90 barrel is the correct length for a PS90 SBR, measuring in at 10.4 inches. The barrel is machined from 4140 chrome-moly steel and features a salt-bath nitride finish that protects it from wear and corrosion. The barrel features a 1:9-inch twist rate and is threaded at the muzzle with M12X1.0 LH threads. Now all that's needed to finish up your build is a PS90 flash hider or thread adapter!

Threaded Barrel Restriction: 
Threaded Barrels have restricted shipping to CA.

Excellent Quality
All I can say is I wish I had done this sooner. The CMMG barrel is excellent quality and there were no issues at all with the installation. A+

Misleading Title. Not 4150 chrome lined.
Thanks for the false advertisement in the title. The title says 4150 chrome lined. The description says 4140. I didn't read the description so I guess it's my fault, but that's bs that you have a title you know is misleading and downright untrue. The barrel is great, but not what I was expecting. Fix the title so others don't make the same mistake.
Would you recommend this? Yes, I would recommend to a friend
