The .45 JR Carbine function modifications are going really well.
The bolt spring is functioning much better. The 27 round mags even work without jamming or other failures.
I have to say that I like the RONI carbine better, even though it cost more.While the JR is better out at 100 yards, I like the compact, more reliable, carbine better.
