I have a Brakeout Compensator from AAC for sale. It is new and has the Rockset and shims. I really don't know how much these are going for but lets say $70 shipped and I may adjust if there are no takers.
The rules say that I can't link any other sites but I do have an Ebay account(01grander) with 100% feedback. Just so you know that I am not going to rip you off. I'll get it shipped off within a day of payment.
First person that posts on this thread not IM. I don't care how you contact me but just post on this page for "dibs".
Sorry for the sideways pic...
The BRAKEOUT™ combines the main features of our industry-leading BLACKOUT™ Flash Suppressors and Muzzle Brakes into a jack-of-all trades option for shooters looking for the widest range of benefits. It combines a rear muzzle brake chamber with the 3-prong front end of our BLACKOUT™ flash suppressors. The open top and closed bottom of the design minimize muzzle rise and environmental disturbance.
*NOT FOR USE ON SCAR 17
Comes with BRAKEOUT™, Rocksett, and shims for installation.
