Self proclaimed "redneck welder from Kentucky" Otter Creek Labs appears to have released the best 556 can to date, according to the Pew Science review released this morning and a glowing review from Alabama Arsenal on YouTube. I will be in the market for a 5.56 dedicated can soon and would much rather support a small shop like this vs a Surefire. Interested to see how they are able to handle the huge demand increase they're likely about to see.
