Impact NBK Thoughts

[FNG1001]

Looking to see if anyone has an NBK & 737 to compare and get their user review on the differences.
I've built a short action lightweight gun. Using a 737r right now on it (works great) but curious what other users' review have been when running an NBK.
Weight difference, lighter bolt, etc. Thanks.

It’s a few ounces lighter, that’s the only difference you’ll notice. Other than that it’s just a 737 with the top cut open to reduce weight.
