2 of 5 Review before received? June 8, 2024
Reviewer: Steven Sabath from Magalia, CA United States  
Still awaiting delivery (which can be verified with tracking information you provided).
Can't speak of quality as of yet. Purchased because of others reviews. Applied for the Veterans discount, never heard back. I couldn't be very specific due to types of jobs held in the military, could of provided a copy of my VA disability determination letter,  but there was no where to upload or send it. Might update review once I've tried the barrel.
