    Excellent engineering. Fits my ACC perfectly.

    Good so far

    I've had mine since shortly after this model was release, and run it with a SDN-6. Everything seems to work fine. No baffle strikes or end cap strikes. That being said, BattleComp said they wouldn't fix the can if it was damaged by use with the 51.0, and AAC said they wouldn't fix the can if damaged during use of the 51.0. FYI. Well built though, and I like it.

    I haven't shot yet but mounted on barrel and test fit my AAC SDN-6. Fits perfect.
