After reading through the hearing loss with electronic muffs thread, I'm considering getting a can for my gun sooner rather than later. While I'd really like to get a TBAC 30P-1, with my meager wage of $20 a week (I'm a high school student, so I can only work part time), I won't be able to get it any time soon. So what's the best can for the money. I'm looking for least accuracy impact, repeatability, and then sound suppression. I don't need it to be QD, just direct thread 5/8-24 UNEF 3B for the can.
