Buddy has one in jail for his 308, the number are very good on the dbs, remember the reading are taken at the ear level and not down range, there are so many good things about these can,, we finished my build a couple months ago so when i get ready to order it's going to be with OSS.
It is also my understanding that the owner also has to have the paperwork on the can in his possession at the range or where ever the can is being used
YEAH,,,finally got my Form 4 back after 8 months and picked up my ARC22AL today, also got my Form 1 back 2 weeks ago for my SBR for the Scorpion,,,,GREAT MONTH
This month has been great-- got back Form 4 for Dead Air HQ and a Form 1 for the SBR on the Scorpion,, still waiting for Form 4 on my 22AL, should be in at the end of NOV.
