Proof SS 6.5 Creedmoor Barrel by Aaron, December 19, 2022
Quality is what I've come to expect from proof. Feed ramps were clean and the chamber looked great. The extension was a little loose for my liking (most likely the upper) so I shimmed it with 0.001 shim stock and everything went together tight.

Awesome barrel by Scotty, December 29, 2017
Quality is very obvious. Groups started shrinking from 1.5 to sub moa at around 100 rounds. I suspect it will get to half moa. Zero malfunctions with an adjustable gas block. Be prepared for the weight, it’s a boat anchor but is worth it.

Proof SS 6.5 Creedmoor Barrel by Aaron, December 28, 2022
Proof consistently puts out quality product. Chamber and throat look good, along with the feed ramps. Haven't shot it yet, but anticipate an accurate barrel. At the price point I don't think you can really go wrong with the proof.
