If i didn't already have a NULA i would really consider the Knight Ultra Light. Mine is actually a 26" barrel and has a slightly heavier contour than the standard Melvin spec build. You cant really compare the two since Melvin will build them to your specs including LOP and the other options like a Jewell trigger.

Im still in the market for a faster twist 45 that weighs close to my NULA. My Savage Pacnor 45 is a heavy beast but it convinced me a 1-22 twist works great. Its just a terrible platform for a Ultra Light build.

BTW i love that scope base. I think ive seen it somewhere before.
