Gotcha. I think my scorpion is the primary fun gun, but will be nice to be able to switch the suppressor around and take ad antshe of the trilug setup.I had an 8.3" barrel in my AR9. It was long enough that some of the 140gr-147gr would go super. Federal 150gr Syntac ammo is a little more expensive, but stays sub.
Isn't the syntec ammo coated? No concerns there in a suppressor? Seems like I recently saw a thread where folks said it was fine, and I'm guessing it's been OK for you?
