Still planning on picking up one of Clint's SPR barrels and a SOLGW NOX, but I've also been thinking the MPR might be worth swapping into one of my other rifles.
Will some of these models be produced for some time?

Here are some OPTIMUM Chrono results to share:
Ammo was slightly older batch IMI M193 55gr FMJ that has shown proper velocities in the past.
Temp was 38F
16" MPR - 3084 fps - This is similar to or slightly better than other 16" barrels we've tested.
11.5" CQB - 2778 fps - Check.
9.0" PDW - 2546 fps - This is a seriously useful velocity from the very compact barrel. This upper cycles very nicely, just like the larger 11.5 CQB.

Just saw that you’re using a 5/8x24 threaded muzzle. Awesome. I’ll be giving one of these a try.

I’ve been using ARP barrels and wanting to pick up a couple extras but he seems to be moving away from the 5/8x24 threaded muzzles and moving to more light weight profiles in 5.56/223wylde. The larger muzzle size does seem to help with accuracy for lighter weight bullets with less bearing surface.

Thought about adding NP3 to the barrel extensions?
