I have a TBAC-22TD and love it. Baffles clean right up in the sonic cleaner. No high power TBAC cans.
I've been in the queue for the AAC since late August. They were out about a year at one point, but the queue is shrinking with more output and slightly less demand. Then again, since the resurface of AAC at PSA and their "no warrantee" statements, I have feeling more will be jumping on conversions and/or recores. I don't recall if ECCO can jailbreak an AAC, perhaps. If he can recore, he should be able to jailbreak one.
I was thinking about picking up my adapters and muzzle devices a week or so ago thinking I surely must be coming up soon and left them all sitting in a cart. Got a heads up today they would be calling the next batch starting Monday and went to checkout and some were OOS. They're plentiful elsewhere, just had to pay a little more.
I'll be putting all my AAC muzzle devices up on the popular local gun board soon. I have one local guy already in the queue for some. The ECCO conversion is only $200 but replacing all the muzzle devices can be a bit of an expense. I could buy another rifle can.
I'll be hand delivering them as they're local to me and he's also going to swap a flash hider that needs a pin/weld on my 14.5 Noveske Recce I never bothered to SBR.
