Swivel macro fitting
Only weakness is that it's hard to take apart without a trap wrench
I got this for my ICD Freestyle V8. The stock regulator would have me shooting anywhere from 255-270fps over a chronograph.. the FIRST time i shot my AKA Sidewinder was over a chronograph, and immediately (WITH ZERO ADJUSTMENT AT ALL) i was getting 266-271. What a huge difference in performance, and the reg isn't even broken in yet.
As long as you've got a strap wrench you'll have an easy time lubing this thing up. it's internals are very simple.
The swivel macro fitting also allows you to screw the reg in all the way without worring which way the macro port will face.
Totally worth the money.
I live in Canada, and AKA shipped it out 3 hours after i ordered it, and they even used USPS so i woulnd't have to pay border fees. GREAT company and they make great products.
